Peripheral Nervous System | histology The CNS consists of the brain and the spinal cord, while the PNS is composed of nerves and groups of nerve cells (neurons), called ganglia. The nerves of the PNS carry sensory (afferent) inputs to the CNS and motor (efferent) output from the CNS to the skeletal and cardiac muscles and the smooth muscles of blood vessels, organs and glands.

Divisions of the Autonomic Nervous System | Anatomy and Physiology I These fibers are unmyelinated. (Note that the term "postganglionic neuron" may be used to describe the projection from a ganglion to the target. The problem with that usage is that the cell body is in the ganglion, and only the fiber is postganglionic. Typically, the term neuron applies to the entire cell.) Parasympathetic Nervous System Functions | Simply Psychology Nerve fibres of the PSNS arise within the central nervous system. The primary nerves involved are cranial nerves.

They are elongated, flattened cells that wrap around axons withinthe PNS, insulating the axon and forming a myelin sheath axon Anatomy, Central Nervous System - StatPearls - NCBI Bookshelf These regions are then broken down into 31 segments with 31 pairs of spinal nerves. There are 8 cervical nerves, 12 thoracic nerves, 5 lumbar nerves, 5 sacral nerves, and 1 coccygeal nerve. Each nerve exits the vertebral column passing through the intervertebral foramina and to its designated location in the body.
