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. 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. : The system includes the Hypothalamus , Pituitary,

: Growth hormone (pituitary) and sex hormones drive physical development and puberty. : The system includes the Hypothalamus

: 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 ).
