| CNS: Brain Function | responsible for initiating, controlling, and regulating sensorimotor and cognitive (mental) functions that generate and regulate human behavior |
| CNS: spinal cord function | transmits motor commands to various body parts; transmits sensory information that is collected from the peripheral body parts and environment to the CNS and brain |
| Protection of the CNS | brain: skull and meningeal layers; spinal cord: vertebral column and meningeal layers |
| PNS | spinal nerves: sensory and motor nerves connected to the spinal cord; cranial nerves: sensory and motor nerves connected to the brain stem |
| two divisions of the PNS | 1. somatic nervous system, 2. autonomic nervous system |
| Somatic Nervous System | involved with voluntary control; includes sensory and motor fibers; innervates muscles and skin |
| autonomic nervous system | aka visceral or vegetative system; involved w/involuntary control; includes sensory & motor neurons; innervates visceral organs & glands; regulates activity of organs e.g. salivary glands, heart, lung, blood vessels, stomach, intestines, kidney, bladder |
