Detailed explanation-1: -The premotor cortex appears to be involved in the selection of appropriate motor plans for voluntary movements, whereas the primary motor cortex is involved in the execution of these voluntary movements. Premotor cortex neurons signal the preparation for movement.
Detailed explanation-2: -The motor cortex controls motor behaviors by generating movement-specific signals and transmitting them through spinal cord circuits and motoneurons to the muscles. Precise and well-coordinated muscle activation patterns are necessary for accurate movement execution.
Detailed explanation-3: -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-4: -The cortex divides into four lobes; frontal, parietal, occipital, and temporal by different sulci. [1] The frontal lobe, located anteriorly to the central sulcus, is responsible for voluntary motor function, problem-solving, attention, memory, and language.
