A
Running when a starting pistol signals the beginning of a race is an activity that encompasses the skeletal system, the muscular system and the nervous system. These systems function interdependently to enable an individual run successfully in a race immediately the pistol shoots (Oleksy, 2010).

a) The structures and the afferent division of the peripheral nervous system that are involved in the activity of running are: skeletal muscles (Diagram 1), sensory or afferent neurons, the
Dendrites, the auditory nerve; the ear (4) the eyes and other sense organs found on the skin. The
peripheral nervous systems (PNS) are made up of the nerves and ganglia found outside the brain and the spinal cord. Its main function is connecting the central nervous system (CNS) with the
Effector organs such as the limb muscles.
b) Two structures of the central nervous system that are involved in the activity of running are; the brain and the spinal cord.

The main part of the brain involved in running is the Cerebellum; it coordinates the motor functions such as regulation of muscle movements and posture. The Cerebellum however has numerous Cranial nerves that aid it in the same.

C). Seven structures of the efferent division of the peripheral nervous system that are involved during the activity of running are; skeletal muscles, cardiac muscles, Motor neuron, efferent dendrites, sympathetic ganglia and parasympathetic ganglia (Oleksy, 2010).
