Endocrinology Of The Adrenal Gland Flashcards
Where is the cortex’s embryological origin
Mesodermal tissue
What did the medulla develop from
Neuronal tissue
What type of hormones does the cortex secrete
Steroid
What type of hormones does the medulla secrete
Catecholamine
(Ex: Epinephrine)
Name the different layers on the cortex
Zona glomerulosa
Zona fasciculata
Zona reticularis
What hormone is made in the Zona glomerulosa
Aldosterone
What hormone is synthesised in the Zona fasciculata
Cortisol
What hormone is made in the Zona Reticularis
Androgens:
Androstenedione
+
Testosterone
What does ACTH act on and through what system
Acts on the anterior pituitary gland through the hypothalamic pituitary adrenal axis
Which region of the cortex does ACTH act upon and what function does it serve
Zona Fasciculata,
Increase uptake of cholesterol to make more hormones.
What hormone type is aldosterone
Mineralocorticoids
What hormone stimulates the release of aldosterone
Angiotensin 2
When is aldosterone released
In response to the RAAS (renin angiotensin aldosterone system)
When blood pressure is low
What type of hormone is cortisol
Glucocorticoids
What is the function of cortisol
Maintain blood pressure
