Nerve tissue is specifically designed to transmit impulses throughout the body, making it essential for communication between different parts of the nervous system. This type of tissue is primarily composed of neurons, which are the specialized cells responsible for sending and receiving signals, as well as glial cells that provide support and protection for neurons.

The roles of nerve tissue include processing information and coordinating bodily functions, which is crucial for everything from reflex actions to complex thought processes. This distinguishes it from the other types of tissue mentioned. Epithelial tissue, for example, serves to cover surfaces and create barriers, while connective tissue provides support, binds other tissues together, and plays key roles in structural integrity. Muscle tissue, on the other hand, is responsible for movement in the body. Each of these tissue types has distinct functions that are fundamentally different from those of nerve tissue, highlighting the specific nature of nerve tissue's role in the body.
