MUSCLE PHYSIOLOGY

Detailed explanation-1: -Voluntary movement is the expression of thought through action. Virtually all areas of the central nervous system are involved in this process. The main flow of information may begin in cognitive cortical areas in the frontal lobe, or in sensory cortical areas in the occipital, parietal and temporal lobes.

Detailed explanation-2: -NARRATOR: The nervous system orders the body’s muscles to contract. We can deliberately order the skeletal muscles to contract, which enables us to perform movements. These voluntary movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe.

Detailed explanation-3: -Voluntary movements are movements that are in direct control of the will of a person. These are controlled by skeletal muscles. For example walking, talking, dancing, etc.

Detailed explanation-4: -Voluntary movements, such as walking upright, are rather complex involving multiple areas within the central (CNS) and peripheral nervous systems (PNS). It is no wonder that it takes time to learn to walk or ride a bike. Once learned, these movements are consciously initiated and then carried out almost automatically.
