Module 2 Lesson 2 - 4

Lesson Summary

Self-regulated by the hypothalamus/pituitary complex, the endocrine system utilizes tropic hormones such as releasing hormone from the hypothalamus and ACTH, TSH, and hGH from the anterior pituitary to stimulate other endocrine glands, such as the adrenal gland and thyroid gland, to produce their hormones. Negative feedback shuts off the tropic hormones when levels of hormones by the target glands reach correct amounts. Disruption in the level of a hormone can cause serious effects on physiological function such as urine production, growth, and metabolic rate.
