work together to perform important roles in the

body, regulate the

electrical and chemical processes; communication systems that work together

to coordinate different physiological functions

and maintain homeostasis

hypothalamus

a tiny collection fo nuclei that links the endocrine and nervous system together

endocrine: main function

regulates long-term bodily functions, secretes hormones

endocrine: communication method

uses hormones (chemical messengers) that are produced by glands

endocrine: target

any cell with hormone receptor

endocrine: response time

it is slower because hormones travel through the bloodstream

endocrine: duration of effect

longer-lasting effects

nervous: main function

controls and coordinates body activities by transmitting signals

nervous: communication method

uses electrical impulses that travel along neurons and neurotransmitters

nervous: target

neurons, muscles, glands

nervous: response time

very fast, often instant

nervous: duration of effect

short-lived responses
