Document Summary

Cns and transmit motor and other commands in the other direction, from the cns to muscles, glands, and internal organs: skeletal nervous system (controls the various muscles, relaying motor commands from the brain) Sensory or afferent: detect information from physical world and pass that information to the brain (light receptor)/ send signals from the body to brain (cns) Sympathetic: promotes the (cid:281)fight-or-flight(cid:282) response, involves high arousal/alertness, mobilizes the body for rapid energy expenditure, and inhibits digestion. Parasympathetic: promotes the (cid:281)rest-and-digest(cid:282) response, enhances the internal processes related to the digestion of food: describe the spinal reflex arc. Spinal reflex arc is controlled entirely at the level of the spinal cord; the brain is not directly involved in producing spinal reflex. Sensory neurons, motor neurons, and interneurons cooperate to move the body away from the pain involve highly functional behavior known as spinal reflex: extra infos.
