Hormone functions

Question 1

Insulin

Answer 1

Muscle and fat: glucose uptake
Liver: glucose uptake

Question 2

Glucagon

Answer 2

Liver: glucose synthesis

Question 3

ADH

Answer 3

Kidneys: Stimulates reabsorption of water

Question 4

Oxytocin

Answer 4

-Stimulates milk release

Question 5

GH RH

Answer 5

Anterior Pituitary gland: releases GH

Question 6

GH IH

Answer 6

Anterior pituitary gland: inhibts GH

Question 7

Growth Hormone (direct and indirect Short term and long term)

Answer 7

Direct:
Muscle- Protein synthesis (LT), inhibits glucose uptake (ST)
Liver: glucose synthesis (ST)
Fat: Triglyceride breakdown (ST)

Indirect:
-causes release of IGF 1 (promotes cell division (LT)
-Promotes growth of bones and muscles

Question 8

TRH

Answer 8

Hypothalamus: makes APL secrete TSH

Question 9

TSH

Answer 9

APL: makes Thyroid gland to secrete T3 and T4

Question 10

Thyroid hormones (T3 and T4)

Answer 10

Metabolism: increase basal metabolic rate

-Stimulates growth
-Normal nervous system

Question 11

Thyroid hormone effects on metabolism

Answer 11

-Breakdown of fat and muscle
- increases in gluconeogenisis and glycogenolysis

Question 12

Parathyroid Hormone PTH

Answer 12

Kidneys:
-Calcium reabsorption (water retention)
-Vitamin D to Calcitriol (calcium absorption from food)
Bone:
-Bone resorption

Question 13

Adrenaline

Answer 13

Skeletal muscle and Liver:
-Breakdown of Glycogen
Fat:
-Breakdown of fat

Question 14

CRH

Answer 14

stimulates APL to secrete ACTH

Question 15

ACTH

Answer 15

Stimulates Andrenal cortex to secrete cortisol

Question 16

Cortisol (metabolic effects and other effects)

Answer 16

Metabolic effects:
Muscle: -Inc protein breakdown
-dec glucose uptake
Fat: -Inc fat breakdown
-Dec glucose uptake
Liver: Inc glucose synthesis

Other:
-Cope with stress
-Long term supression of immunte system
-Maintain normal blood pressure
