NARES (Nasal cavities).
The nares are the cavities in the head extending through the nose to the pharynx. The walls of the nares are smooth, and, with their turbinated bones, suggest the inside of a sea-shell.
PHARYNX.
The pharynx is a membranous sac. It has seven openings, the two posterior nares, the two Eustachian tubes, the larynx, the œsophagus, and the isthmus faucium, which is the opening into the mouth.
