What is a larynx model?
A larynx model is an indispensable tool for anyone who wants to understand the human larynx. A larynx model reproduces the anatomy of the larynx and is especially used in teaching and training. The model makes it possible to see and touch the structures one reads about in books. For example, a larynx model helps medical students, educators, and healthcare professionals visualize complex details that might otherwise be difficult to imagine. The larynx model differs from other anatomical models like the ear or eye by focusing on both voice production and airways. In 2025, the larynx model has become even more central due to new teaching methods and increased digitalization.

Definition and purpose
A larynx model is a precise, physical replica of the human larynx. The purpose of a larynx model is to enable the user to learn about the structure, function, and relation of the larynx to other structures. The model is particularly useful for medical students, educators, and healthcare professionals who need a tangible understanding. Compared to other models, such as those showing the ear, a larynx model offers unique insight into voice production and airway protection. In 2025, the larynx model has become even more relevant as modern teaching methods demand more interactive learning.
Historical development and technological advances
The development of larynx models has accelerated in recent years. Previously, models were often simple and made from formaldehyde-containing materials that could cause allergic reactions. Today, most larynx models are made from synthetic, safe materials that pose no health risk. With 3D printing, it is now possible to produce detailed, layered models that can be disassembled and reassembled. Statistics show that the use of 3D-printed larynx models in education has increased significantly. For example, eAnatomi has developed 3D dissection models without risk of infection, which is an advantage for both pregnant students and allergy sufferers.
Types of larynx models
There are several types of larynx models, each with its own advantages. The most commonly used are fixed models, movable models, enlarged models, and microscopic models. An enlarged, five-part larynx model provides detailed insight, while a movable model with vocal cords is suitable for demonstrating functions. The disadvantage of fixed models is that they cannot always be disassembled, while movable models offer more practical training. Statistics from Denmark show that enlarged models are particularly popular at universities, while simple models are often used in high schools.
Typical materials and quality
The choice of material for a larynx model is crucial for both durability and learning outcomes. The most common materials are plastic, resin, silicone, and 3D-printed composites. A quality larynx model is easy to clean and can withstand repeated use. Color-coding of tissues and structures helps to facilitate learning; for example, blue is used for cartilage, brown for muscles, and red or yellow for vessels and nerves. Teaching models place high demands on precision and detail so that the user gets the most out of their larynx model.
Advantages of using larynx models
The advantages of using a larynx model in teaching and training are numerous. First and foremost, it significantly improves the understanding of anatomical relationships. A larynx model allows for practical, risk-free training and makes it easier to visualize complex structures. The model supports both individual and group instruction, which increases engagement and learning outcomes. A larynx model is therefore a valuable tool for anyone working with anatomy in 2025.
Larynx Anatomy: The Most Important Parts Explained
The anatomy of the larynx is central to understanding how the voice is formed and how the airways are protected. A detailed review of the most important parts helps both students and healthcare professionals get the most out of any larynx model. Each structure has its own function, and their interaction can best be experienced through a thorough, visual model.
Overview of the main structures of the larynx
The larynx, also called the voice box, is located between the pharynx and the trachea. It functions both as a vocal organ and as a protector of the airways against foreign bodies. A larynx model clearly shows how these functions are realized through division into several sections.
The model also illustrates the relationship to nearby organs, for example, the placement of the thyroid gland just in front of the larynx. By using a larynx model, one can easily visualize how the larynx is divided into different anatomical layers, which significantly strengthens understanding.
Cartilaginous structures and joints
The most important cartilages in the larynx are the thyroid, cricoid, arytenoid, and epiglottis cartilages. In a larynx model, these are often color-coded, so cartilage appears blue. The joints, cricothyroid and cricoarytenoid articulations, allow for movement and adjustment of the vocal cords.
The table below provides a quick overview:
| Cartilage | Function |
|---|---|
| Thyroid | Protects vocal cords |
| Cricoid | Supports larynx |
| Arytenoid | Movement of vocal cords |
| Epiglottis | Closes off airways |
The larynx model particularly helps students avoid typical misconceptions about the placement and mobility of the cartilages.
Muscles and mobility
Laryngeal muscles such as the thyrohyoid and cricothyroid muscles are crucial for voice quality and airway patency. A larynx model with removable muscles allows examination of how the muscles work together to open and close the vocal cords.
Movable models provide additional value in clinical training, as they mimic the physiological movements encountered in practice. By working with a larynx model, the user gains a more concrete understanding of the role of the muscles and their interplay.
Vessels and nerves
The blood supply to the larynx primarily comes from arteries, which are often marked in red on a larynx model. Nerves, typically yellow, are crucial for both motor and sensory function in the larynx. The model makes it easy to follow the course of nerves and vessels, which is essential in a surgical context.
Knowledge of vessels and nerves in relation to the larynx is important for understanding how diseases and interventions can affect the voice or airways. The larynx model provides an opportunity to practice these aspects safely and clearly.
Related structures: Thyroid gland, parathyroid, and trachea
The larynx model also shows related structures, such as the thyroid gland in front of the larynx and the parathyroid glands, of which there are normally four, but often only two are visible on the model. The trachea consists of horseshoe-shaped cartilaginous rings that continue below the larynx, and the hyoid bone forms the upper boundary.
For educators who wish to integrate larynx models into teaching, useful resources can be found on Information for educators, where guidance and tips for optimal use are available. A larynx model that includes these related structures provides a complete picture and strengthens the understanding of anatomical relationships.
How to use a larynx model in teaching and training
Using a larynx model in teaching opens up a deeper understanding of both anatomy and function. With a larynx model, complex structures can be visualized, which strengthens both theoretical and practical learning. Below, the most important applications and considerations are reviewed.
Practical applications in teaching
A larynx model is used in anatomy education at both high school and university levels. The model makes it possible to demonstrate voice production and the structure of the airways in a concrete way. Students often work in groups where they can disassemble the model, examine the parts, and compare them with anatomical illustrations.
Examples of exercises:
- Demonstration of vocal cord movement
- Identification of vessels and nerves
- Laryngoscopy practice on the model
Statistics show that the use of larynx models in medical studies has increased significantly in recent years. This is due to the model's ability to make teaching both more interactive and understandable.
Clinical scenarios and understanding of diseases
Larynx models also play a central role in clinical education. The model helps students and healthcare professionals understand conditions such as epiglottitis, polyps, goiter, laryngeal edema, and cancer. Through physical visualization, it is easier to see how diseases affect the structures.
Typical applications:
- Training in examination methods
- Simulation of surgical procedures
- Discussion of treatment options
A larynx model makes it possible to demonstrate the consequences of, for example, laryngeal cancer, which strengthens understanding and prepares students for clinical situations.
Advantages of physical models vs. digital solutions
Physical models offer tactile learning, where parts can be disassembled and examined from all angles. This provides a spatial understanding that digital solutions cannot always match. Many students prefer a physical larynx model over VR or AR, especially in group exercises.
Comparison table:
| Physical model | Digital solution |
|---|---|
| Tactile sensation | Virtual visualization |
| Can be disassembled | Limited interactions |
| Requires storage | Available online |

Choosing the right model for the purpose
The choice of larynx model depends on the target group and the purpose of the teaching. For detailed understanding, an enlarged model is recommended, while a movable model is suitable for demonstrating functions. Price and quality should be weighed against the need, especially if the model is to be used for clinical training or exam preparation.
Considerations when choosing:
- Fixed vs. movable model
- Degree of detail and size
- Price, durability, and area of application
Universities often choose advanced models, while high schools prefer simpler versions. A good larynx model ensures that both theoretical and practical learning are strengthened for all users.
Step-by-step: How to understand the structure of a larynx model
Mastering a larynx model requires a structured approach. With this step-by-step guide, you will get a clear overview of how to work systematically with the model to gain the maximum benefit from both anatomy and practical understanding.
1. Start with an overall overview
Always begin by placing the larynx model on a stable surface. Take your time to study the entire model as a whole to get a sense of its proportions and structure. Use color codes and clear labels to identify main structures such as cartilage, muscles, vessels, and nerves.
It can be beneficial to compare your larynx model with anatomical illustrations or posters. Many students find that visual aids like anatomical posters designed in Denmark provide extra clarity, especially when complex details need to be understood. Also note the model type and size, for example, whether it is enlarged 2x or life-size.
A good start is to create a mental map of the model's parts and their placement. This makes it easier to navigate when you later need to disassemble and examine the individual components.
2. Disassembling the model into parts
The next step in working with a larynx model is to examine how the model can be disassembled. Many models can be split in half, making both internal and external structures visible. Identify which parts can be removed, such as muscles or individual cartilages.
Modular division has great pedagogical value. When you physically remove and reassemble the parts, you gain a better understanding of how the anatomy fits together. Try to separate the thyrohyoid or cricothyroid muscle and see their relation to other structures.
A practical exercise is to assemble and disassemble the larynx model repeatedly. This strengthens spatial awareness and makes it easier to remember details for exams or clinical practice.
3. Review of each individual part
Now is the time to thoroughly examine each component of your larynx model. Start with the cartilages, noting differences in shape and placement. Move on to muscles, vessels, and nerves, and use labels and color codes to identify their function and course.
You may want to compare the right and left sides of the model, as some models show extra details on one side, such as removable muscles. Also assess how the thyroid gland lies in relation to the larynx, and how vessels and nerves run close to the structures.
For each structure, you should consider its clinical relevance. What diseases or interventions relate to this part? This approach strengthens both anatomical knowledge and clinical understanding.
4. Understanding the relationships between the parts
A larynx model allows you to see how the individual structures work together. Examine movement in joints and muscles, and observe how the position of the vocal cords changes during speech or breathing.
Create a small table where you compare functions and relationships:
| Structure | Function | Relationship |
|---|---|---|
| Thyroid cartilage | Protects vocal cords | Connects muscles |
| Cricothyroid muscle | Tenses vocal cords | Located anteriorly |
Use the model to demonstrate the interplay between vessels, nerves, and cartilage. Simulate voice production by moving the relevant parts, and consider how diseases can affect these relationships in practice.
5. Apply the model in case-based learning
An effective way to test your understanding of the larynx model is to work with case-based learning. Use the model to simulate diseases such as laryngeal edema or polyps, and discuss how symptoms arise.
For example, take a case where a patient has swelling in the larynx. Use the larynx model to show which structures are affected and how the airways can become blocked. Discuss examination methods and consider treatment based on the model's anatomy.
This activates your knowledge and better prepares you to apply it in clinical situations where rapid assessment is crucial.
6. Evaluate your understanding and repeat the process
Always conclude by evaluating your learning. Test yourself or your fellow students by pointing to structures or explaining relationships on the larynx model. Use the model to identify weak points in your knowledge and repeat relevant steps.
Incorporate feedback from instructors, and don't be afraid to repeat the process multiple times. Studies show that repeated use of a larynx model leads to significantly better learning outcomes and greater confidence in both exam situations and clinical practice.
This systematic approach ensures that you gain an in-depth understanding of both anatomy and practical application.
Maintenance, storage, and durability of larynx models
Regular maintenance of your larynx model ensures both hygiene and longevity. Cleaning should always be performed with mild detergents approved for plastic and resin. Avoid formaldehyde and other strong chemicals, as these can damage the surface. Follow a step-by-step approach: Remove dust with a soft cloth, gently wash with lukewarm water and mild soap, and dry the model thoroughly after use. After group instruction, disinfection with an alcohol-based wipe is recommended, especially if multiple people have handled the model. Statistics show that properly cleaned models can last up to 10 years. Practical experiences from the Human Anatomy and Histology course also emphasize the importance of cleaning to keep the larynx model in optimal condition.
Storage and transportation
Proper storage protects your larynx model from damage and extends its lifespan. The model should be stored dry, away from direct sunlight, and at room temperature. Use a stand or a padded storage box to prevent bumps and scratches. For transportation in educational settings, it is recommended to secure the model in a stable container so that loose parts do not shift. In universities and clinics, locked cabinets are often used for storage, minimizing the risk of loss or damage. Small adjustments to routines can make a big difference to your larynx model's durability.
Durability and repair
A quality larynx model can last for many years with proper use. Typical signs of wear include loose muscles, fading of color markings, or breakage of delicate joint parts. If damage is detected, spare parts should be ordered directly from the manufacturer. Many models come with a warranty and the option for claims, making repair affordable. Replacement of individual parts, such as muscles or joints, can often be done without special tools. Statistics from Danish suppliers show that the average lifespan of a high-quality larynx model is 8-12 years, depending on use and maintenance.
Environment and sustainability
Synthetic larynx models have several environmental advantages over real specimens. They are often made from recyclable materials such as plastic or resin, which reduces environmental impact. Production also reduces the need for formaldehyde and other harmful substances. Many manufacturers focus on sustainability and safety for both users and the environment. For example, several Danish companies prioritize recycling and eco-labeling in their production, so you can choose an environmentally friendly larynx model with a clear conscience.
