Myelinated axon from a central nervous system neuron (mammal; longitudinal section), transmission electron micrograph (TEM). Microtubules and neurofilaments are present in the axon cytoplasm. Neurons are (also known as nerve cells) are cells of the nervous system that are specialized to carry messages through an electrochemical process. They have special cells called astrocytes (also known as astroglia) that are a type of neuroglial cell that provides support functions in the central nervous tissue and spinal cord. They perform a variety of tasks, from axon guidance and synaptic support, to the control of the blood brain barrier and blood flow.
