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 |
