A few cards from the deck
Growth hormone (GH): what is it?
Show the answer
An anterior pituitary hormone that stimulates growth of bone and tissue, partly through liver IGF-1.
Its excess gives gigantism in children, acromegaly in adults.
Fatigue, feeling cold, weight gain, high TSH and low T4: what is it?
- Hypothyroidism of thyroid origin
- Hyperthyroidism
- Type 1 diabetes
- Cortisol excess
Show the answer
Hypothyroidism of thyroid origin
The thyroid makes little, the pituitary pushes harder: TSH rises.
TSH: what is it?
Show the answer
An anterior pituitary hormone that stimulates the thyroid.
It rises when the thyroid makes too little: it is the first test to order.
What is negative feedback in a hormonal axis?
- The final hormone brakes the hormones that drive it
- The final hormone stimulates the hormones that drive it
- The final hormone stimulates its own gland
- Target cells stop responding to the excess hormone
Show the answer
The final hormone brakes the hormones that drive it
T4 brakes TSH, cortisol brakes ACTH: the system stays stable.
