The nervous system structurally consists of billions of nerve cells (neurons) and support cells (glial cells). Based on its anatomical localisation, it is subdivided into the central nervous system (CNS) and the peripheral nervous system (PNS).
The CNS comprises the brain hemisperes, the cerebellum, the brainstem and the spinal cord. The grey matter of the central nervous system consists of large numbers of cell bodies of neurons. The white matter consists of nerve fibres sheathed in myelin. The PNS consists of nerve bundles comprised of afferent and efferent nerve fibres that are connected to the spinal cord via the foramina of the spine.
The function of the nervous system is to transmit information. Stimuli are perceived by sensory cells, processed, and transferred to effectors in the body such as muscle or gland cells. In other words, the nervous system records, interprets and reacts. It is also the seat of our consciousness and our cognitive capacities.
