Nervous Tissue Nervous tissue senses stimuli and transmits signals called nerve impulses from one part of an animal to another. Nervous tissue is primarily located in the brain and spinal column. Nervous tissue contains neurons, or nerve cells as well as support cells called glial cells, or simply glia. Neurons are the basic units of the nervous system. A nerve cell consists of a cell body and long extensions called dendrites and axons, which transmit signals from place to place. A neuron receives nerve impulses from other neurons via its cell body and multiple extensions called dendrites. Neurons transmit impulses to neurons, muscles, or other cells via extensions called axons, which are often bundled together into nerves.
