Peripheral nervous technique The peripheral anxious program definition is the fact that it conducts details from the CNS to your concentrate on tissues, and from the target tissues into the CNS. It is made up of nerves as well as their ganglia. Nerves that carry details from peripheral feeling organs (for example eye, tongue, nasal mucosa, ear, skin) to your CNS are known as the ascending, afferent or sensory nerve fibers. Fibers that carry facts from the CNS for the periphery (muscles and glands) would be the descending, efferent, motor or secretory nerve fibers.
