Adrenal Gland Flashcards
Adrenal cortex
Three classes of steroid hormone
Glucocorticoids – cortisol
Mineralocorticoids – aldosterone
Androgens – DHEAS and androstenedione
Control of glucocorticoid secretion
Adrenal medulla
Sympathetic nervous system
Produce catecholamines (adrenaline and noradrenaline)
Adrenal cortex hypo function
Addison’s disease
Weakness, anorexia, weight loss, hypertension, lethargy
Adrenal gland stopped working
Adrenal cortex hyper function
Cushing’s syndrome
Acne, weight gain, thin skin, slow wound, healing
Excess cortisol
Conns syndrome
Hypertension(sodium and water retention ), muscle weakness
Excess mineralocorticoid , caused by adrenal adenoma
Adrenal medulla metabolic effects
Moderate secretion of other hormones
Increases glycogen breakdown
GluconeoGenesis
Increases release of amino acids, lactate and pyruvate
