I. ANATOMY OF THE CAT

Digestive and Respiratory Systems, Exercise 4, p. 191-198.

Accomplish entire exercise with the following OMISSIONS:

molar gland, p. 191

infraorbital gland, p. 191

To expose the inside of the mouth, cut the inside corner on each side of the mouth. To preserve the neck muscles, do not attempt to view the pharynx region on your cats. Instead, I have prepared a sagittal section of the head. Be sure to spend some time looking at this. Also note that the muscles of the chin can be viewed from this sagittal section. These include the genioglossus, geniohyoid, and mylohoid.

When cutting open the abdominal cavity, try to cut directly down the midline of the body so that the rectus abdominis is not destroyed. Remove a majority of the mesentery and associated fat.

To view the portions of the larynx described on p. 196, again do not use your cats or the musculature associated with the neck will be destroyed. Instead, view this region on the sagittal sections of the head and neck.

When exposing the thoracic cavity, cut through the side of the chest that you have not used to separate the pectoral musculature.
