Document Summary

White vs grey matter (organization in brain vs spinal cord) White matter made of axons connecting different parts of grey matter to each other. Consists of primarily myelinated axons in 3 types of tracts. Grey matter contains cell bodies, dendrites and axon terminals of neurons where all synapses are. Brain: grey matter on outside/white matter on inside. Spinal cord: grey matter on inside/ white matter on outside. Cortex: surface anatomy (fissures, sulci & gyri) Gyri = corticol region rolls and folds on itself: anterior motor vs posterior sensory, cerebral lobes & their associated function (lateralization of function) Special areas (frontal eye field, bro(cid:272)a(cid:859)s, wer(cid:374)(cid:374)i(cid:272)ke(cid:859)s, pri(cid:373)ary (cid:373)otor/se(cid:374)sory) Bro(cid:272)a(cid:859)s = located in frontal lobe speaking and understanding language. Wer(cid:374)i(cid:272)ke(cid:859)s = left temporal/parietal lobe interprets meaning of speech by recognizing spoken words. Primary sensory = usually receive input both from the primary areas and from other brain regions. Primary motor = controls voluntary contractions of specific muscles or groups of muscles.
