What do tropic hormones primarily do?

Stimulate organ functions
Stimulate other glands to release hormones
Produce energy in cells
Regulate body temperature

The correct answer is: Stimulate other glands to release hormones

Tropic hormones are specifically important in the endocrine system as they play a critical role in stimulating other glands to release hormones. These hormones are produced by the pituitary gland, which is often referred to as the "master gland" because of its role in regulating various bodily functions through hormone signaling. For example, thyroid-stimulating hormone (TSH) from the anterior pituitary stimulates the thyroid gland to produce thyroid hormones, which are essential for metabolism. Similarly, adrenocorticotropic hormone (ACTH) prompts the adrenal cortex to release cortisol, a key hormone involved in stress responses and the regulation of metabolism. The function of tropic hormones underlines how endocrine communication works; they serve as messengers that target other glands, effectively orchestrating responses and maintaining homeostasis within the body. This highlights their significance in the broader context of hormonal regulation and interaction among various systems in the body.
