Study Notes

Hormones play a crucial role in the body, secreted by glands in the endocrine system such as the hypothalamus, pituitary, thyroid, parathyroid, thymus, adrenal glands, pancreas, and gonads.
Endocrine glands release hormones directly into the surrounding areas without ducts, while exocrine glands have ducts that carry secretions to body openings or surfaces.
Major endocrine glands include the hypothalamus, pituitary, thyroid, parathyroid, thymus, adrenal glands, pancreas, ovaries, and testes, each producing specific hormones for various functions.
Hormones can be derived from different biomolecules like amino acids or lipids, influencing their structure and function, including binding to specific target cells and triggering various cellular responses.
The hypothalamus-pituitary complex plays a crucial role as the "boss" of the endocrine system, producing hormones like oxytocin, growth hormone, prolactin, thyroid-stimulating hormone, and more.
Other glands like the pineal gland secrete melatonin for regulating circadian rhythms, while the adrenal glands produce hormones like epinephrine, norepinephrine, cortisol, and aldosterone for different body responses.
The pancreas releases insulin to help cells take in glucose for energy and glucagon to raise blood glucose levels, while gonads produce hormones like estrogen, progesterone, and testosterone for various functions in males and females.
