1. What is a tropic hormone? Give an example.
2. Describe the many ways one hormone can affect another hormone's activity.
3. What are the 2 hormones secreted by the posterior pituitary and what are their functions?
4. What are the 6 major hormones produced and secreted by the anterior pituitary and what are their functions?
1. a) A tropic hormone is a hormone that regulates the secretion of another hormone. b) An example of a tropic hormone is thyroid-stimulating hormone (TSH), which regulates the production and release of thyroid hormones.

2. a) One hormone can affect another hormone's activity by directly stimulating or inhibiting its production. b) Hormones can also interact with each other at the receptor level, enhancing or blocking each other's effects. c) They can also compete for binding sites on target cells, leading to either potentiation or inhibition of activity. d) Hormones can also affect each other's metabolism and breakdown within the body.

3. a) The two hormones secreted by the posterior pituitary are oxytocin and antidiuretic hormone (ADH). b) Oxytocin is involved in labor and lactation, as well as social bonding. c) ADH regulates water reabsorption by the kidneys, helping to maintain water balance in the body.

4. a) The 6 major hormones produced and secreted by the anterior pituitary are: b) Growth hormone (GH), which promotes growth and protein synthesis. c) Thyroid-stimulating hormone (TSH), which regulates the production of thyroid hormones. d) Adrenocorticotropic hormone (ACTH), which stimulates the adrenal glands to produce cortisol. e) Follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which regulate the reproductive system in both males and females. f) Prolactin, which is involved in lactation and reproductive function in females.
