Document Summary
Major systems: nervous system- uses neurons to send and receive information through electrical and chemical communication. Has a short duration, only when a stimulus is present: endocrine system- uses the bloodstream to send and receive information through chemical communication. Reactions are longer-lived, and remain active even after the stimulus is no longer present. The nervous system: functions: to receive and input information (input, processing and integration of information received (processing, performing some type of reaction in response to the information received (output) Somatic nervous system- controls skeletal muscles; regulates voluntary movements. Autonomic nervous system- controls body systems involuntarily, such as vital organs or glands. Sympathetic nervous system- one of the two divisions of the autonomic nervous system; prepares you to react to stimuli ( fight or flight response), causes the body to become aroused. Parasympathetic nervous system- also one of the two divisions of the autonomic nervous system; relaxes and calms the body down, as well as preserves energy.
