Study Notes

The nasal cavity is enclosed within the bones of the face.
The nose develops as an inpocketing and thickening of the surface ectoderm.
Turbinate bones increase the surface area of the nasal epithelium for smell and cleaning/warming the air.
The pharynx is the area between the mouth and the larynx.
The larynx provides a sphincter and controlled entrance for the airway, vocalization, and effort closure in relation to raising intra-abdominal pressure.
The larynx is lined with mucous membrane supplied by branches of the vagus nerve.
The epiglottis deflects food, but effort closure of the larynx is performed by sphincter muscles surrounding the laryngeal opening.
All but one of the small muscles of the larynx are supplied by the recurrent laryngeal nerve.
The vocal folds run from the anterior (vocal) processes of the arytenoids to the back of the thyroid cartilage.
The sounds produced by the vocal folds rely on the thickness and length of the string.
