BIO161-Nerve Chart
Nerve Chart
| Nerve, Structure, Etc | AKA | Location | Function |
|---|---|---|---|
| Frontal lobe | (blank) | anterior aspect of each cerebral hemisphere | motor |
| Parietal lobe | (blank) | medial aspect of each cerebral hemisphere | general touch (pressure, temperature, etc) |
| Temporal lobe | (blank) | over the temporal bone of each cerebral hemisphere | hearing |
| Occipital lobe | (blank) | posterior aspect of each cerebral hemisphere | vision |
| precentral sulcus (precentral gyrus?) | area 4; primary motor area | anterior to central sulcus | skilled voluntary movement (i.e. fine motor skills) |
| premotor cortex | area 6; motor association area | anterior to the precentral sulcus | memory bank of previously acquired fine motor skills |
| Broca's area | motor speech area | frontal lobe; found only in the dominant hemisphere | controls the speech muscles (tongue, orbicularis oris, etc) |
| prefrontal cortex | (blank) | (blank) | judgement, inhibitions, depth of feeling, and personality |
| postcentral gyrus | primary sensory area; primary somesthetic area; areas 3, 1, 2 | parietal lobe | (blank) |
| parietal secondary sensory area | sensory association area | parietal lobe | memory bank of previously felt sensations |
| primary visual cortex | area 17 | occipital lobe | vision |
| secondary visual | areas 18 and 19 | occipital lobe | relates to past visual experiences |
| primary auditory cortex | (blank) | superior margin of temporal lobe | hearing |
| auditory association areas | (blank) | temporal lobe | memory bank of previously heard sounds |
| olfactory cortex | (blank) | both frontal and temporal lobes (piriformis and uncus) | smell |
| gustatory cortex | (blank) | parietal lobe | taste |
| vestibular cortex | (blank) | insula lobe | balance and equilibrium |
| cerebellum | little brain | lies immediately dorsal to the pons and medulla and protrudes below the occipital lobe | 1) coordinates movement (i.e. fine-tunes movement); 2) works with vestibular part of brain for balance & equilibrium; 3) cognition |
| Wernicke's area | (blank) | temporal lobe | abilitity to sound out unfamiliar words |
| spinothalamic tract | (blank) | parietal lobe | pain, temperature; effects are manifested contralaterally |
| fasciculus cuneatus and fasciculas gracilis | (blank) | (blank) | light touch, tickling, propioception, vibration |
| corticospinal tract | (blank) | precentral gyrus of the frontal lobe | voluntary movement commands |
| thalamus | (blank) | part of diencephalon; directly below the corpus callosum | acts as a relay station - directs impulses to the proper part of the brain |
| hypothalamus | (blank) | inferior to the thalamus | controls many visceral activities in the body |
| epithalamus | (blank) | superior to the thalamus | produces CSF (thru choroid plexus) and melatonin for the sleep/wake cycle (thru the pineal body) |
| basal ganglia | basal nuclei | within the cerebral white matter | initiating and monitoring movements, especially stereotypic movements (ex: normal walking gait) |
