An overview of the primary motor cortex function tells us that various regions of the cerebral cortex are involved in planning of the voluntary motor functions in the human body. The primary motor cortex function also includes the subsequent processes like controlling and executed the planned motor action.
The anatomy of the motor cortex reveals four parts including the primary motor cortex that is also referred by the abbreviation M1. The primary motor cortex function is to generate the neural impulses that are required for the execution of the motor activities in the human body.
The other parts are grouped under the category of secondary motor cortex and these include the posterior parietal cortex, premotor cortex and supplementary area cortex.
According to studies it has been revealed that the other parts of the brain like the cerebellum and the sub cortical nuclei also play an important part in the primary mortar cortex function in the human body.
