divisions of nervous system

autonomatic nervous system

Controls the glands and muscles of internal organs. It regulates the automatic behavior is necessary for survival. Has two subdivisions, one responsible for mobilizing us during stressful situations, in the other for calming us when the emergency has passed

sympathetic nervous system

arouses the body during emergencies by accelerating heartbeat, slowing digestion, raising blood sugar, dilating arteries, and creating precipitation. This prepares a body for an energetic physical response to a threat or challenge, including the challenge of sexual intercourse

Central Nervous System (CNS)

includes most of the neurons in the body. It handles the information processing in decision-making tasks. Sensory information from the outside world and from inside the body is channeled through the peripheral nervous system (PNS) and gets analyzed in the CNS. If some action is required, the CNS organizes a response and communicates the message through the peripheral nervous system to the appropriate muscles or internal organs

somatic nervous system

part of the peripheral nervous system (PNS)that carry sensory information and controls body movement

Peripheral nervous system (PNS)

subdivided into the somatic nervous system (which carries sensory messages from skin and muscles, and controls the bodies movements), and the autonomic nervous system, (which communicates with and regulates the internal organs, largely outside conscious awareness).

Parasympathetic division

subdivision of autonomic nervous system. Relaxes the body after the emergency has passed, by producing the opposite affects, slowing heartbeat, stimulating digestion, lowering blood sugar, contract in the arteries, and shutting down perspiration. responsible for the localized sexual arousal of the genitals in both female and males. Although this connection to sexual arousal may seem an exception to the usual tendency of the parasympathetic division to come the body it makes sense in terms of survival, having engorged genitals would not be a useful response in the presence of danger, when the sympathetic division is activated

two parts of the autonomic nervous system

sympathetic division makes you sizzle (arouses you for action) parasympathetic division pacifies you (calms you down"
