Nervous Tissue Mediates Perception and Response

Definition

Nervous tissue is a specialized tissue in the body that is responsible for transmitting signals between the brain and other parts of the body to mediate perception, such as sensing changes in the environment, and initiating appropriate responses. It consists of neurons, which process and transmit these signals, and glial cells, which provide support and protection for neurons.
