Document Summary
The nervous system functions are to communicate and integrate functions between the body systems. Neurons are the cells of neural tissue that are specialized to generate and conduct electrical impulses (nerve impulses) Nerve impulses allow information to be conducted (communicated) between two areas. Neural impulses conduction and distribution along neural pathways allows integration of body functions. Central nervous system (cns)- central processing and integration of information by the brain and spinal cord. The cns receives sensory input from the peripheral nervous system (pns) which it processes and determines the appropriate response that are sent back out to the pns via motor pathways. Peripheral nervous system (pns)- includes all neural tissue outside the central nervous system. Efferent division- all outgoing motor pathways carrying instruction from the cns to the effector organs (muscle, glands, or adipose: somatic nervous system- controls skeletal muscles, autonomic nervous system- controls smooth muscle, cardiac muscle, glands or adipose.
