Decent Essays

The nervous system is one of the most important systems in your body. The functions of the nervous system consist of sensory input, which means to gather information. Sensory input monitors the changes occurring inside and outside of the body. Another function is integration. This processes and interprets sensory input and decides if any action is needed. The last major function of the nervous system is motor output. Motor output is a response to integrated stimuli. The response activates muscles or glands. The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. The nervous system also contains the Central and Peripheral nervous system.

The peripheral nervous system is abbreviated as PNS. This system is the part of the nervous system that consists of the nerves and ganglia on the outside of the brain and spinal cord. In this system the nerves extend from the brain and the spinal cord. Two nerves that are included in the peripheral nervous system are spinal and cranial nerves. The spinal nerves carry impulses to and from the spinal cord. The cranial nerves carry impulses to and from the brain. The function of the peripheral nervous system is to serve as a communication lines among sensory organs, the brain and spinal cord, and glands or muscles. This system consists of mixed, sensory and motor nerves. The mixed nerves consists of both sensory and motor nerves. The sensory nerves run from stimulus receptors that inform the central nervous system of the stimuli. The sensory nerves are considered afferent. The motor nerves run from the central nervous system to the muscles and glands, called effectors that take action. The motor nerves are considered efferent. The peripheral nervous system is split into the sensory-somatic nervous system and the autonomic nervous system. The sensory-somatic nervous system consists of twelve pairs of cranial nerves and thirty-one pairs of spinal nerves. This nervous system transmits sensory information from the body to the brain and motor movements from the brain to the body. The autonomic nervous system is the
