Document Summary
Divisions of the nervous system: cns (central nervous system): brain and spinal cord, pns (peripheral nervous system): somatic system (spinal nerves) visceral system (autonomic nervous system): parasympathetic and sympathetic. Medial (midline): looking from cutting brain in and looking in. Dorsal: back (or top referring to brain) Ventral: front or belly (or bottom referring to brain) Sagittal: runs rostral-caudal (midsagittal cuts in the middle, anything else is sagittal) Horizontal: like transverse; cuts brain into top and bottom. Coronal: like frontal; cuts brain into front and back. Cerebrum/cerebral cortex: 2 cerebral hemispheres divided by the sagittal fissure (midline: concerned with contralateral movement and sensation. Cerebellum: 2 hemispheres: concerned with ipsilateral motor control. Brain stem: most primitive part: concerned with life functions-respiration, body temperature. Spinal cord: conduit of information and from brain: sensory and motor losses following section. Forebrain: part of the brain toward the front: cerebral cortex and thalamus (where retina is)
