GROSS ANATOMY

Detailed explanation-1: -The Primary Motor Cortex : Upper Motor Neurons That Initiate Complex Voluntary Movements. The upper motor neurons in the cerebral cortex reside in several adjacent and highly interconnected areas in the frontal lobe, which together mediate the planning and initiation of complex temporal sequences of voluntary movements.

Detailed explanation-2: -Frontal Lobes These include motor skills such as voluntary movement, speech, intellectual and behavioral functions. The areas that produce movement in parts of the body are found in the primary motor cortex or precentral gyrus.

Detailed explanation-3: -The primary function of the motor cortex is to generate signals to direct the movement of the body. It is part of the frontal lobe and is anterior to the central sulcus.

Detailed explanation-4: -The motor cortex sends voluntary motor commands to the spinal cord but can also be involved in involuntary movements [17, 38–42].
