The part of the cerebral cortex that receives projections from the motor thalamus and which projects to motor neurons in the brainstem and spinal cord. The motor cortex corresponds to Brodmann's area 4 (MM). The primary motor cortex, or M1, is located on the precentral gyrus and on the anterior paracentral lobule on the medial surface of the brain. Of the three motor cortex areas, stimulation of the primary motor cortex requires the least amount of electrical current to elicit a movement. http://neuroscience.uth.tmc.edu/s3/chapter03.html.

- TODO - in MA this is asserted to be part_of BOTH frontal and parietal cortex. in ABA these are disjoint. FMA makes no commitment beyond cerebral cortex. Wikipedia says frontal lobe. Check if species difference or difference in definition. Removed relationship: part_of UBERON:0001872 parietal lobe
