In vertebrate anatomy, the throat is the front part of the neck, internally positioned in front of the vertebrae. It contains the pharynx and larynx . An important section of it is the epiglottis , separating the esophagus from the trachea (windpipe), preventing food and drinks being inhaled into the lungs .
Movements of the neck includes: flexion, extension, (nodding yes), and rotation (shaking head no). The mouth has evolved to support chewing, (mastication) and swallowing (deglutition), and speech (phonation). In addition to the teeth, other structures that aid chewing are the lips, cheeks, tongue, hard palate, soft palate, and floor of the mouth.

In facial expression, this mouth line is iconically shaped like an up-open parabola in a smile, and like a down-open parabola in a frown. A down-turned mouth means a mouth line forming a down-turned parabola, and when permanent can be normal. Also, a down-turned mouth can be part of the presentation of Prader–Willi syndrome. [4]
The epiglottic valleculae are paired spaces between the root of the tongue and anterior surface of the epiglottis.Each vallecula is bordered medially by the median glossoepiglottic fold and laterally by the lateral glossoepiglottic fold.
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species.

Gross anatomy has become a key part of visual arts. Basic concepts of how muscles and bones function and deform with movement is key to drawing, painting or animating a human figure. Many books such as "Human Anatomy for Artists: The Elements of Form", are written as a guide to drawing the human body anatomically correctly. [4]
