Endocrine Physiology May 2026

: Hormones like insulin and glucagon (from the pancreas) and thyroid hormones ( T3cap T sub 3 T4cap T sub 4 ) manage energy use and blood sugar levels.

The endocrine system is a network of glands that secrete chemical messengers called hormones directly into the bloodstream to regulate distant target organs.

: While the "classical" pathway involves hormones traveling through the blood, they can also act on nearby cells ( paracrine ) or even the secreting cell itself ( autocrine ).

For more specialized or clinical perspectives, you might explore Endocrine Physiology: Hormones and Their Role in Regulation or the open-access LibreTexts section on Endocrine Physiology .

: The system includes the Hypothalamus , Pituitary, Thyroid, Adrenal glands, Pancreas, and gonads (ovaries and testes). Core Functions :

: Most endocrine functions are controlled by negative feedback , where the body's response to a hormone signal eventually turns off the original stimulus to maintain stability.

For a comprehensive introduction to , the article Physiology, Endocrine Hormones by StatPearls on the NCBI Bookshelf is an excellent resource. It covers the fundamental mechanisms of how hormones regulate homeostasis, metabolism, and reproduction. Key Components of Endocrine Physiology
