  1. Taste aversion
  2. Vagus nerve
  3. Splanchnic nerve
A
  1. Is a distaste for food that develops if the food makes one ill.
  2. Conveys information about the stretching of the stomach walls to the brain.

Q

The lateral hypothalamus contribute to feeding by:

A
  1. Detecting hunger and sending messages to make food taste better
  2. Arousing the cerebral cortex to facilitate ingestion, swallowing and to increase responsiveness to taste, smell and sights of food
  3. Increasing the pituitary gland’s secretions of hormones that increase insulin secretions
  4. Increasing digestive secretions

Q

Effect of lesions in certain hypothalamic areas;

  1. Preoptic areas
  2. Lateral preoptic areas
  3. Lateral hypothalamus
  4. Ventromedial hypothalamus
  5. Paraventricular nucleus
A
  1. Preoptic areas - deficit in physiological regulation of temperature regulation
  2. Lateral preoptic areas - deficit in osmotic thirst
  3. Lateral hypothalamus - undereating, weight loss, low insulin level, underarousal, underresponsiveness
  4. ventromedial hypothalamus - increase meal frequency, weight gain, increase insulin level
  5. Paraventricular nucleus - increase meal size, esp. Carbohydrates

Q

Body temperature regualators

A

> Preoptic area/ anterior hypothalamus - monitoring body’s temp. By monitoring it’s own temp.

Q

Definition of terms

Vasopressin

A

> Hormone release by posterior pituitary which raises blood pressure by constricting blood vessel.
Helps to compensate for the decrease blood pressure
Also known as anti-diuretic hormone because in enables the kidney to reabsorb water and excrete highly concentrated urine
