cat dissection thoracic + abdominal

Vestibule

the space between the cheeks and eardrum

Filiform papillae

thread like bump on the front part of the cat’s tongue

Where do you find the taste buds?

On tiny bumps called papillae

Palatine ridges

transversal ridges across the roof of the cat’s mouth (hard palate)

Soft palate

Divides the oral pharynx vertically from the nasal pharynx and provides a barrier during swallowing.

Epiglottis

The flaps that protects the glottis (slit like opening that leads to trachea) during swallowing and prevents food from entering the airway.

Trachea

Windpipe - c shaped rings that allow compression + airway + connects the larynx

Larynx

Voice production/ vocal cords + during swallowing, epiglottis folds over the larynx to seal of the airway, preventing food from going to the trachea + regulates breathing.

Esophagus

transport food and liqud from the pharynx + line with smooth muscles that contract rhythmically.

Peristalsis

Rhythmic contractions due to the smooth muscles in the esophagus that move food to the stomach + out of control

Choking process

Food obstructs the trachea —> Muscles move up so the epiglottis flap folds over the larynx to seal the airway and prevent food from entering the trachea.

Heimlich maneuver

Use when choking + clear complete airway by forcing air from the lungs to expel the object obstructing the trachea.

Incisors

snipping + 12 (3 in each quadrant)

Canine tooth

Ripping and tearing (human have hands to do these so canine are reduced) + 4 (one in each quadrant)

Pre molar

Crushing + 10 (3 in each upper quadrant, 2 in each lower quadrant)

Molar

Grinding + 4 (1 in each quadrant)

Liver

filtering toxins from blood + produce bile for digestion + regulate blood sugar levels

• 5 lobes

  • right lateral

  • right medial

  • left lateral

  • left medial

  • caudate lobe

Gallbladder

Stores bile and releases to the duodenum

greater omentum

fat storage + immune responses

Stomach

digestion and storing

cardiac sphincter

controls the entrance of food into the stomach from the esophagus

Pyloric sphincter

regulates the release of partially digested food into the duodenum

Small intestine

1. duodenum

   • common bile duct and pancreatic duct open into

2. jujenum

   • absorbs nutrients from digested good into bloodstream

3. ileum

   • velvety texture due to the presence of villi

Mesentery

The membrane that holds the small intestine

Large intestine

1. caecum or secum

   • Ileocecal sphincter

2. Ascending colon, transverse colon, descending colon, rectum

   —> absorption of water

Pancreas

Pancreatic duct enters the duodenum together with the common bile duct

helps with digestion by producing enzymes that break down food

produce insulin and glucagon

Spleen

tied to the stomach of the greater omentum known as the gastrosplentic ligament

• immune system and blood filtration

Kidney

Includes the adrenal glands on top

• filter waste products from the blood and produce urine

Urinary bladder

Store urine
