Nervous System Flashcards
frontal, temporal & occipital.
poles
supero-lateral, medial & inferior.
surfaces
supero-medial, infero-lateral &infero-medial
borders
frontal, parietal, temporal , occipital & limbic.
lobes
separates the frontal lobe anteriorly from the parietal lobe posteriorly.
The central sulcus
separates the temporal lobe inferiorly from both frontal &parietal lobes superiorly.
The lateral sulcus
limits the occipital lobe posteriorly from the parietal lobe anteriorly.
The parieto-occipital sulcus:
consists of dense collections of myelinated fibers
White matter
Bundles of nerve fibers (neuron processes)
White matter
Bundles of nerve fibers (neuron processes)
running through the CNS are
tracts
Bundles of nerve fibers (neuron processes)
running through the PNS are
nerves
unmyelinated regions of the CNS (unmyelinated fibers and cell bodies)
Gray matter
small collections of cell bodies are found in a few sites outside the CNS in the PNS.
Ganglia
located in the parietal lobe posterior to the central sulcus
The primary somatic sensory area
allows to recognize pain, differences in temperature, or a light touch
