Document Summary

Primary motor cortex skilled and precision movement. Receives info from may cerebral areas including parts of the: anterior frontal lobe parietal and temporal lobe and performs executive. Topographic organization: representations are proportional to the use and sensitivity of each area of the body. Cerebral cortex: thin plate (3-5mm) thick consisting of 6 layers from the pial surface to the white matter. Cortical cytoarchitecture: all cortical areas consist of 6 layers. The thickness and cell densities of each layer vary between cortical areas. Thalamic input terminates mainly in layer 4. Thalamic fibers project to small granule (stellate) cells in layer 4. Granule cells project to small pyramidal cells in layers 2 and 3. Cells in layers 2 and 3 project to large pyramidal cells in layers. 5 and 6: cortical columns are functional units of the cerebral cortex that are patches of cells. 6 cell layers total and cells are interconnected within the columns.
