Caption: Pyramidal neurons from the central nervous system growing on a fibroblast matrix. Note the large dendrite (and axon) coming from opposite ends of the pyramidal cell bodies. Neurons exist in varying sizes and shapes throughout the central nervous system (CNS). Neurons are responsible for passing information around CNS and from the CNS to the rest of the body. Each nerve cell is composed of a cell body surrounded by numerous extensions (processes) called dendrites. In the case of a pyramidal nerve cell there is one major apical dentrite and few basal dendrites (not seen in this image). Dendrites collect information from other nerve cells or from sensory cells. Each neuron also has one process called an axon, which passes information to other nerve cells, or to effector cells such as muscle fibers.
