Adrenal Glands Flashcards
Aka
Suprarenenals
Outer portion
Adrenal cortex
Middle portion
Adrenal medulla
Electrolytes
Mineral substances (calcium, chloride, magnesium, phosphorus, Na, K) that are normally found in the blood and other bodily fluids
function of the adrenals
Control electrolyte levels
Other important functions
Regulate metabolism and interacting with the sympathetic nervous system in response to stress
Androgens
Secreted by AG, gonads, adrenal cortex, and fat cells
Sex hormones
Corticosteroids
Steroid hormones produced by the adrenal cortex
Aldosterone
Corticosteroid that regulates the sodium and water levels in the body by increasing sodium reabsorption and potassium excretion by the kidneys
Cortisol
Hydrocortisone, corticosteroid that has anti-inflammatory action
Regulate the metabolism of carbohydrates, fats, and protein in the body
Epinephrine
Secreted by adrenal medulla
Adrenaline
Stimulates the sympathetic nervous system in response to physical injury or to mental stress
Heart beat faster
Raise bp
Helps the liver release glucose and limits the release of insulin
norepinephrine
Both hormone and neurohormone
Released as a hormone by the adrenal medulla and neurohormone by the sympathetic nervous system
Raises bp
Strengthening the heartbeat
Stimulating muscles contractions
