'''Nervous Tissue''' is one of the four major classes of [[vertebrate]] [[tissue]] (the other three being [[Epithelium]], [[Connective tissue]] and [[Muscle tissue]]). Nervous tissue is the primary means that an organism has of exchanging information or commands between various [[organs]] and other tissues. It is divide into two categories: the first is [[neurons]] and the second is [[neuroglial]]. Neurons make up the functional form of the tissue most of the communication and integration of information occurs with neuronal tissue. Neuroglial primarily provide structural and metabolic support for the neurons. However, some parts of the neuralglial aid in neuronal communication by insulating the [[axons]] that propagate the electrical signal allowing for faster transfer of information.
The complete collection of nervous tissue in an organism makes up its [[nervous system]] which is responsible for perceiving sensory data, integrating and processing information and controlling behavioral responses.
