Document Summary

Differentiate between the central nervous system and the. Knee-jerk: brainstem: begins where the spinal cord enters the skull, receives afferent nerves coming from senses and sends efferent nerves out to control movements (afferent to the brain and efferent away from the. Flying and landing in birds and catching prey in cats; slower moving animals have smaller cerebellums: reticular formation: reticular activating system, netlike mixture of neurons (gray matter) and nerve fibers (white matter). Regulation of emotional and sexual behaviours, memory, motivation and spatial navigation: amygdala, hippocampus, cingulate cortex. All the neurons in the body located outside the brain and spinal cord: skin: sensory connections to receptors, muscle: motor connections to body muscles, internal organs: sensory and motor connections. The brains main function is to produce behaviour, to do this it must receive information about the world, integrate information to create a sensory reality and produce commands to control the movement of muscles.
