: 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 ).
: 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. Endocrine Physiology
: 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.
: Aldosterone and Antidiuretic hormone (ADH) regulate blood pressure and hydration. Physiological Principles For more specialized or clinical perspectives, you might
The endocrine system is a network of glands that secrete chemical messengers called hormones directly into the bloodstream to regulate distant target organs.
: Cortisol (adrenal glands) coordinates the "fight or flight" response. : Hormones like insulin and glucagon (from the
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
