Webb9 feb. 2024 · The primary motor cortex is a region of the motor cortex which is important for initiating motor movements. The areas of the primary motor cortex correspond precisely to specific body parts. The primary motor cortex contains large neurons (nerve cells) with triangular-shaped bodies called pyramidal neurons. WebbThis prominent gyrus is called the precentral gyrus, and it comprises the majority of what is known as the primary motor cortex (area 4). The term motor strip is also used for this area. Nerve fibers composing a large motor pathway called the pyramidal tract descend into the brain and spinal cord from starting points in the primary motor area. data analytics community
