Description
Nerve cell. Computer artwork of a nerve cell or neuron. Neurons are responsible for passing information around the central nervous system (CNS) and from the CNS to the rest of the body. Each nerve cell comprises a body surrounded by numerous extensions called dendrites. Dendrites collect information from other nerve cells or from sensory cells. Each neuron also has one process called an axon (lower left), which passes information to other nerve cells, or to effector cells such as muscle fibres. It appears segmented as it is surrounded by a myelin sheath, which contains gaps, called nodes of Ranvier. The myelin insulates the axon, allowing signals to be transmitted more quickly.
