The peripheral nervous system (PNS) consists of all neural tissue outside of the brain and spinal cord. It is made up of cranial and spinal nerves, ganglia (clusters of nerve cell bodies), and sensory receptors. Sensory neurones or afferent neurons are a key component of the PNS, responsible for transmitting information from sensory receptors in the body to the central nervous system (CNS).
