Endocrine Physiology -

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

: Growth hormone (pituitary) and sex hormones drive physical development and puberty.

: Cortisol (adrenal glands) coordinates the "fight or flight" response. Endocrine Physiology

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 The endocrine system is a network of glands

: The ultimate goal of these hormonal interactions is to maintain a constant, balanced internal environment regardless of external changes.

: 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. Physiology, Endocrine Hormones - StatPearls - NCBI Bookshelf

: 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 ).
