Enlarged throat, 7 parts

Anatomically speaking, the larynx model primarily shows the larynx/throat (larynx) with the laryngeal cartilages (blue), the laryngeal muscles (brown) and the larynx's vascular and nerve supply (in red and yellow respectively). The model also shows the 2 closing mechanisms, which are the larynx (epiglottis) and vocal folds (plicae vocales) as well as the 2 joints (articulatio cricothyroidea and cricoarytenoidea).



On the right side of the model, the thyroid gland can be seen in orange (glandula thyroidea), which in front covers the lower part of the larynx and the upper part of the windpipe (trachea). The trachea in blue forms the lower part of the model and is seen with the characteristic "horseshoe-shaped" rings of cartilage. On the back of the thyroid gland are 2 of the parathyroid glands (normally there are 4 in humans).



Above the larynx, the bone of the tongue can be seen in sand color (os hyoideum), muscles etc. Although the pharynx is not defined on the back of the model, you can still sense/imagine a part of this vertical tube.



The model can be separated into 7 parts as follows:



From top to bottom (from the tongue bone to the lower end of the model's trachea), the model can be split "in the middle"
If the model is divided as mentioned above, the right part can also be divided at the lower edge of the thyroid cartilage
The thyroid cartilage can be split in two and removed
Furthermore, 2 muscles can be removed from the left side of the model (m. thyrohyoideus and m. cricothyroideus)
