In contrast to it, the system of voluntary control. Specifically, an autonomic nervous system manages such divisions as connections between spinal, brain, and other organs. They primarily relate information through the cranial nerves to the ' dorsal root ganglia of the spinal cord, with motor commands carried by the efferent fibers leave the cord at the ventral roots. According to the medical theory, the somatic nervous control refers to all voluntary body movements while autonomic system regulates involuntary impulses of a human body. Sensory neurons carry messages from the nerves to the central nervous system and vice-versa, and relay information such as light, touch and sound. Examples of this include when your hand quickly retracts from a hot stove, or when your knee jerks after a doctor taps on it. This means the muscle movement can happen almost automatically, not needing input from the brain. The autonomic nervous system deals with the.

It is responsible for all the functions we are aware of and can consciously influence, including the movement of our arms legs and other parts of our body. The somatic nervous system is made up of nerves that extend from the brain to the skin and muscles. These occur when a nerve pathway connects directly to the spinal cord. The somatic nervous system is a component of the peripheral nervous system associated with the voluntary control of the body movements via the use of skeletal muscles. Some acts of the somatic nervous system are involuntary, however, as in muscle reflex arcs. Motor neurons only recieve instructions for the muscle fibers to perform, such as lifting a hand or running through a park.

Motor neurons control muscle movement with commands recieved from the precentral gyrus, which travel to the neurons via spinal nerves located on the spine. The somatic nervous system houses two different types of neurons: Motor (efferent) neurons, and Sensory (afferent) neurons. In contrast, the somatic nervous system controls all voluntary muscle movement and reflex arcs, and is also responsible for processing information gathered externally, such as sight, touch, sound, taste, smell and others. The autonomic nervous system control involuntary processes in the body, such as digestion, heart rate, urination and the fight-or-flight response. The somatic nervous system is part of the peripheral nervous system, along with the autonomic nervous systems.
