A note on Neural, Astrocyte and Oligodendrocyte Markers for Central Nervous System


Neurons are electrically excitable cells in the Central Nervous System (CNS) and Peripheral Nervous System (PNS) that send and acquire electrical impulses and neurochemical signals to process information. Neurons drive activity in the brain, spinal cord, and peripheral sensory and motor systems. They are exceedingly specialised to rapidly transmit electrical alerts and neurotransmitters throughout synapses. Although there is an extensive range of neuronal types and morphologies in the nervous system signals are typically received on the cell body or dendrites and sent out alongside the axon. Neurons are regularly recognized by observing expression of cell-specific intracellular proteins, such as NeuN etc.
