Document Summary

Nervous system: cns: all enclosed in bone (brain+spinal cord, pns: everything else. Views of brain: dorsal (looking down from above, ventral (looking from below, lateral (looking from side, medial/midline (cutting brain in half) Planes through brain: midsagittal: along midline, horizontal, coronal: inhalf from top. 2 cerebral hemi divided by sagittal fissure (midline) Concern w/life functions (respiration, body temp: spinal cord. Grey matter: inside (neurons, cell bodies, axon terminals+dendrites) Spinal cord: 31 segments, each has 2 spinal nerves (left, right, dorsal root: sensory, ventral root: motor. 5 regions: cervical (8, thoracic (12, lumbar (5, sacral (5, coccygeal (1) Bring sensory info to cns from peripheral: efferent(dorsal root): sensory. *on skin surface, that sensory region=a dermatome (not on face) 12 pairs come directly off brain (take care of function in head) Me(cid:374)i(cid:374)ges: (cid:862)(cid:272)o(cid:448)e(cid:396)i(cid:374)g(cid:863: du(cid:396)a mate(cid:396): (cid:862)ha(cid:396)d (cid:373)othe(cid:396)(cid:863)- think like leather, a(cid:396)a(cid:272)h(cid:374)oid: (cid:862)spide(cid:396)(cid:863, pia mate(cid:396): (cid:862)ge(cid:374)tle (cid:373)othe(cid:396)(cid:863) Ventricular system: series of ventricles/canals that move csf w/in brain.
