Endocrine System -the nervous system allows for quick messages to be delivered from the brain to the body -this allows the body to quickly respond to stimuli from the environment -in contrast, the endocrine system releases hormones to maintain homeostasis and regulate long-term, ongoing processes in the body

Endocrine System -hormones: chemicals released by glands and cause slow changes in the body -hormones have target cells that will respond to its presence -both the nervous system and the endocrine system can use the same chemical messenger (epinephrine) a neurotransmitter and hormone

Endocrine System -both are usually regulated by negative feedback loops -both share the goal of maintaining homeostasis -when hormone levels reach a certain normal or necessary amount, further secretion is controlled by body organs and glands to maintain that level of hormone in the blood

Endocrine System -major endocrine organs include: -hypothalamus -pituitary master gland -pancreas -thyroid -adrenal glands -ovaries -testicles
