Study Notes

Salivary Glands

Main salivary glands in cats: parotid, submandibular, sublingual, and molar glands.
Sublingual gland is positioned deep to the submandibular duct.

Larynx and Swallowing

The epiglottis serves to close the entrance to the larynx during swallowing.
The mylohyoid muscle aids in swallowing by elevating the floor of the mouth.

Abdominopelvic Cavity

The peritoneal membrane covers both the walls of the abdominopelvic cavity and the organs within it.
Key organ: the liver, recognized as the largest organ in the abdominal cavity.
The stomach, located on the left side and partially obscured by the liver, is a large muscular pouch.

Digestive Organs

Accessory digestive organs: liver, gallbladder, pancreas, and their associated ducts.
The small intestine comprises three parts: duodenum, jejunum, and ileum.
The common bile duct unites with the pancreatic duct, emptying into the duodenum.

Mesenteries

The parietal peritoneum lines the abdominal wall, while the visceral peritoneum covers organs.
The greater omentum, a dorsal mesentery, connects to the greater curvature of the stomach.
The falciform ligament carries the remnant of the umbilical vein to the liver.

Nervous Innervation

Dorsal and ventral facial nerves innervate facial muscles and run across the masseter muscle.
The hypoglossal nerve, located medial to the digastric muscle, controls tongue muscles.

Esophagus and Trachea

The esophagus can be distinguished from the trachea due to the lack of cartilage in its structure.

Organ Classification

Retroperitoneal organs are not suspended by a mesentery.
Nutrient absorption primarily occurs in the small intestine, not the large intestine.

Tooth Structure

Components of a tooth include crown, neck, root, enamel, dentin, pulp cavity, cementum, periodontal ligament, and root canal.
