Throat with vocal cords, 5 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 is seen 1 of the parathyroid glands (normally there are 4 in humans).



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



At the top of the model you can see the tongue with various papillae, 2 salivary glands on the right side (glandula submandibularis and sublingualis), a bit of the mandible in sand color (mandible) as well as 4 incisors, the 2 canines and the 4 small molars (premolars).



The model can be separated into 5 parts as follows:



The lower jaw with the tongue and some muscles can be separated from underlying structures
The tongue can be separated from the lower jaw bone and divided in half (ie 3 parts)
Underlying structures with e.g. the larynx and trachea can be divided in half
