Lecture 2 Flashcards
CNS (central nervous system) : brain and spinal cord :: ___ : neural parts outside of the CNS
PNS (peripheral nervous system)
encephalon, cerebrum, cerebral hemispheres, basal ganglia, limbic lobe
structures / divisions of the CNS
Brodmann areas 44 and 45 which play a role in fluent, well-articulated speech are also known as ___’s area
Broca
frontal lobe : most anterior :: occipital lobe : most ___
posterior
parietal lobe : superior to sylvian fissure :: temporal lobe : ___ to sylvian fissure
inferior
lobe involved with language (left), motor planning, and executive functioning
frontal lobe
lobe involved with language (left), sensation, and spacial information
parietal lobe
lobe involved with auditory processing and semantic memory
temporal lobe
lobe involved with processing visual information
occipital lobe
cortex found in pre central gyrus (BA 4) in frontal lobe; sends signal for execution of voluntary motor movements - somatotopically organized (homunculus)
primary motor cortex
cortex found in post central gyrus (BA 1, 2, & 3) in parietal lobe; receptor for bodily sensations - somatotopically organized
primary somatosensory cortex
cortex found in Heschl’s gyrus (BA 41 & 42) in temporal lobe; processes incoming sound - tonotopically organized
primary auditory cortex
cortex found along calcimine fissure (BA 17) in occipital lobe; processes visual signals - retinotopically organized
primary visual cortex
higher order processing cortex which takes info from primary sensory cortex (temporal, parietal, and occipital lobes) to performs additional processing; also, ___ cortex flows backward when sending information to primary motor cortex in the frontal lobe so that final execution commands may be sent out
association cortex
primary sensory cortex : temporal-parietal-occipital :: primary ___ cortex : frontal
motor
