What is the function of the Primary Motor Cortex?

The primary motor cortex controls voluntary movements. Damage to the primary cortex would impact the ability to control voluntary movement.


Where is located the primary motor cortex?

The primary motor cortex is located in the precentral gyrus of the the frontal lobe of the cerebrum.


What represent the motor areas of the cortex?

Primary motor cortex, premotor cortex, Broca's area and frontal eye field

What central lobe of the brain is the primary motor cortex?

The somatic motor cortex is located in the human brain. It can be found in the posterior portion of the frontal lobe.


Is the primary motor cortex the surface of the precentral gyrus?

Yes :)


What sulcus separates the primary motor cortex fron the primary sensory cortex?

The central sulcus is a fold in the cerebral cortex of brains in vertebrates. Also called the central fissure, it was originally called the fissure of Rolando or the Rolandic fissure, after Luigi Rolando.The central sulcus is a prominent landmark of the brain, separating the parietal lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex.


Which part of the brain is most superior to the skull?

What are motor areas of the cerebral cortex that lie in the posterior part of the frontal lobes and control voluntary movement?

primary motor cortex; premotor cortex; Broca's area; frontal eye field


What part of the brain controls motor behavior?

Motor functions are controlled in the motor cortex (particularly, the primary motor cortex and premotor cortex), which are substantially located in the parietal lobe (roughly the rear third of the top of the brain).
