Nerve cells. Fluorescent light micrograph of neurons (nerve cells, red) and glial cells (support cells, green and blue). The glial cells have been genetically engineered to express green fluorescent protein in their cell bodies. Neurons are responsible for passing information around the central nervous system (CNS) and from the CNS to the rest of the body. Each neuron comprises a cell body surrounded by numerous extensions called dendrites. Dendrites collect information from other neurons or from sensory cells. Each neuron also has one process called an axon, which passes information to other neurons, or to effector cells such as muscle fibres. Glial cells provide structural support for neurons and supply them with nutrients and oxygen.
