Sensory Areas
Sensory areas of nervous system---chapter 14 in A+P book
Sensory area | location | function |
---|---|---|
primary somatosensory | post-central gyrus of parietal lobes | receives input from somatic sensory receptors in skin and muscles |
primary visual | posterior tip of occipital lobe | receives visual info from retina |
primary auditory | superior temporal lobe | receives input from cochlear receptors |
primary gustatory | parietal lobe | perception of taste |
primary olfactory | medial surfaces of temporal lobe | receives impulses from olfactory receptors and gives awareness of odor |
primary motor | pre-central gyrus of frontal lobe | conscious control over skeletal muscles |
Broca's speech | anterior and inferior to pre-motor cortex | motor speech area |
somatosensory association | posterior to primary somatosensory | integrate and analyze sensory input to complete picture of what is being felt |
visual association | surrounds primary visual cortex | interprets and evaluates stimuli |
auditory association | inferior to primary auditory | integrates and interprets sound information |
Wernicke's area | posterior temporal lobe of left hemisphere | understanding of spoken and written language |
common integrative | parts of temporal, parietal and occipital lobes | "knowing" area |
premotor | anterior to primary motor cortex | controls learned motor skills |
frontal eye field area | anterior to premotor; superior to Broca's area | controls voluntary eye movement |
