so theres two parts of the nervous system brain ad spinal cord. figure 17.7 is really helpful.
spinal cord: extends from base of rain to verteral canal. vertabraes act as cushions and protect it. gray matter= inside white matter= outside
KNOWWW THE FUNCTIONSSS OF THE SPINAL CORD
communication b/w brain and body, center for many reflex arcs
brain: cerebrum, the two hemispheres. divided by longitudial fissue( like on a map)
sulci= the grooves
