Document Summary
Looks at whats going on, integrates, produces outcome. The nervous system controls everything in your body. Somatic ns sensory and motor (from skin and muscles back to ns) Autonomic ns involuntary functions (heart, blood vessels, kidney, etc) Diffuse enteric ns digestive tract, intestinal motility don"t worry about cranial nerves in the text. The brain is at a right angle to the spinal cord (for humans) and parallel for 4 legs. Posterior part of the spinal cord is dorsal. Diencephalon (-thalamus) thalamus- takes information and sends it out to another place relay hypothalamus controls autonomic functions. Central sulcus divides frontal lobe and parietal lobe. Sylvian fissure/temporal, lateral sulcus divides temporal lobe from everything. Gray matter- cortex and the cell bodies and dendrites inside. White matter- axons and fibers coming and leaving cortex, surrounded by myelin. 4 ventricles (holes) make cerebral spinal fluid (mini circulatory system for the brain) made in the 2 lateral ventricles and flows down.
