Name the hormone of the pituitary gland that fits each target and action.
- It acts on the thyroid and makes it release its hormones.
- It acts on the mammary glands and starts the formation of milk.
- It acts on the kidney and reduces the loss of water.
- It acts on the melanocytes of the skin.
- It induces ovulation of a mature follicle.
Need a reminder? The key ideaShow
Pars distalis: GH, PRL, TSH, ACTH, LH, FSH. Pars intermedia: MSH. Pars nervosa: oxytocin and vasopressin (ADH). The kidneys filter 180 L of fluid in a day. ADH makes the distal tubules reabsorb more water, so the urine is less in volume and more concentrated.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. (a) TSH, the thyroid stimulating hormone.
Step 2. (b) Prolactin (PRL).
Step 3. (c) Vasopressin, the antidiuretic hormone (ADH).
Step 4. (d) MSH, the melanocyte stimulating hormone.
Step 5. (e) LH, the luteinising hormone.
Answer: (a) TSH; (b) prolactin; (c) vasopressin (ADH); (d) MSH; (e) LH.
