Nervous Tissue:

Nerve cells or neurons are the main constituent of nervous tissues. Cell body is the main component of nerve cell. This nerve cell consists of nucleus and axon, which has a very long structure. There exist nerve fibres, which result because nerve cells are joined end to end. A nerve is composed of various nerve fibres.
