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.
