The organ of voice in the neck, a framework of cartilages that guards the airway during swallowing and produces sound by vibrating the vocal folds.
One opener, many closers: the posterior cricoarytenoid alone abducts the cords, and the recurrent laryngeal nerve runs every intrinsic muscle except cricothyroid.
Pharyngeal Arches
Six numbered embryonic arches of the head and neck; the fifth is rudimentary or absent, so the clinically important arches are 1, 2, 3, 4 and 6, each with its own nerve, cartilage, artery and muscles.
Triangles of the Neck
Sternocleidomastoid divides each side of the neck into an anterior and a posterior triangle, each further subdivided.
The Tongue
A muscular organ of taste, speech and swallowing, split by a V-shaped groove into an oral and a pharyngeal part with different nerve supplies.
The Palatine Tonsil
A pair of lymphoid masses in the side walls of the throat that help defend against inhaled and swallowed germs, forming part of a protective ring.
Pharyngeal Pouches and Their Derivatives
The pouches lining the inside of the developing throat between the pharyngeal arches, which form several important head and neck structures.
The Bony Orbit
The cone-shaped bony socket that holds and protects the eyeball, formed by several skull bones.
