Document Summary
Central nervous system is made up of the brain and the spinal cord. Peripheral nervous system is broken down into a component called the somatic division. Stretch information is received to the cns through the somatic division in. Think of the cerebral cortex as the big boss , it tells everyone else what to do and when to do it. Think of the thalamus, basal ganglia, pons, and cerebellum as being second in command. All signals must travel through brainstem to get to spinal cord. Doesn"t do anything in terms of modifying signals. The spinal cord is a slave system to all the above. When someone has a problem with their cerebral cortex, they cannot do precision movements but on power (gross) movement. Can only move hands and fingers at same time. Because no signals can be sent to spinal cord, you know what is going on around you but cant respond.
