Hormones Flashcards
1
Q
ACTH
- Location
- Class
- Function
A
Adrenocorticotropic Hormone
- Location: anterior pituitary
- Class: peptide/water soluble
- Function: causes adrenal cortex to release stress hormones called GLUCOCORTICOIDS
2
Q
LH
- Location
- Class
- Function
A
Leutinizing Hormone
- Location: anterior pituitary
- Class: peptide/water soluble
- Function: surge in LH levels —> OVULATION, also stimulates secretion of estrogen and testosterone
3

Follicle Stimulating Hormone
- Location: anterior pituitary
- Class: peptide/water soluble
- Function:
1. Stimulates growth of the follicle during menstrual cycle,
2. Production of sperm
4
Q
TSH
- Location
- Class
- Function
A
Thyroid Stimulating Hormone
- Location: anterior pituitary
- Class: peptide/water soluble

5
Q
hGH
- Location
- Class
- Function

- Location: anterior pituitary
- Class: peptide/water soluble
- Function: stimulates growth throughout the body
6
Q
Prolactin
- Location
- Class
- Function
A
- Location: anterior pituitary
- Class: peptide/water soluble
- Function: stimulates milk production in the breasts
7
Q
ADH
- Location
- Class
- Function
A
Anti Diuretic Hormone “no-pee hormone”
- Location: posterior pituitary
- Class: peptide/water soluble
- Function: causes the CD of the nephron to become highly permeable to water so that water in the body is retained, and the urine is very concentrated
Think about what your body is going to do if you’re trapped in the desert with no access to water.
8

A
The “cuddle” hormone, released during orgasm and child birth
—have an orgasm during child birth to make labor quicker
- Location: posterior pituitary
- Class: peptide/water soluble
- Function: stimulates contractions during childbirth and milk secretion during nursing
9
Q
PTH
- Location
- Class
- Function
A
Parathyroid Hormone
- Location: parathyroid
- Class: peptide/water soluble
- Functions:
1. Increases blood Ca++ by stimulating proliferation of osteoclasts
2. Increases uptake if Ca++ in the gut
3. Promotion of reabsorption if Ca++ in the kidney
10

11
Q
Glucagon
- Location
- Class
- Function
A
- Location: pancreas
