Chapter 10 Part 3 Flashcards
Two separate adrenal glands
Adrenal cortex and the adrenal medulla
Location of adrenal cortex and adrenal medulla
Adrenal cortex is the outter part of the adrenal gland the adrenal medulla is the inner part of the adrenal gland
Hormones secreted by the three cell layers or zones of the adrenal cortex
Corticoids
Outer zone of the adrenal cortex secretes hormones called…
Mineralocorticoids (MCs)
Main mineralocorticoid hormone
Aldosterone
Middle zone of the adrenal cortex
Glucocorticoids
Chief glucocorticoid
Cortisol or hyrdrocortisone
Innermost or deepest zone of the Adrinal cortex
Small amount of sex hormones
Function of mineralocorticoids
Helps control the amount of certain mineral salts
Function of aldosterone
Increase the amount of sodium and increase the amount of potassium in the blood
Effects of aldosterone on kidneys
Speed up kidney reabsorption of water
Function of glucocorticoids
Maintains normal blood glucose concentrations
Gluconeogenesis
Glucocorticoids increases this, a process that converts amino acids or fatty acids to glucose and is performed mainly by liver cells
Glucocorticoids also play an important role in
Maintaining normal blood pressure,
Anti inflammatory effect,
Anti immunity, anti allergy effect
Adrenal medulla hormones
Epinephrine and norepinephrine
