This is possible because of the somatic nervous system.
The peripheral nervous system's somatic nervous system (SNS), also known as the voluntary nervous system, is responsible for the voluntary regulation of skeletal muscle-based body motions.
The somatic nervous system is made up of motor nerves carrying efferent nerve fibers that relay motor commands from the central nervous system (CNS) to cause muscle contraction and sensory nerves carrying afferent nerve fibers that relay feeling from the body to the CNS.
The human body has 43 nerve segment segments. A pair of sensory and motor neurons are associated with each segment. The spinal cord contains 31 segments of nerves, and the brain stem contains 12 segments of nerves. Thousands of association nerves are also found in the body in addition to these.
Therefore, the somatic nervous system is divided into two sections:
Spinal nerves are mixed nerves that send motor orders into the spinal cord and sensory data into them.
The nerve cells that enter and exit the brain stem are known as cranial nerves.
The senses of taste, smell, mouth, ear, neck, shoulders, and vision are among them.
Therefore, all of the body's voluntary muscle systems and the process of voluntary reflex arcs are under the control of the somatic nervous system.
