Which statement correctly describes nerve tissue?

Nerve tissue is primarily composed of neurons and glial cells, and its main function is to transmit and process information throughout the body. Neurons facilitate rapid communication by sending electrical impulses and releasing neurotransmitters, allowing for quick responses to stimuli. This specialization for information transmission is fundamental in functions such as reflex actions, sensory perception, and coordination of body activities.

The other statements pertain to different types of tissues: muscular tissue is responsible for contraction and movement; epithelial tissue covers internal and external surfaces of the body; and muscular or cardiac tissue is involved in locomotion and pumping blood. Each of these tissues has distinct structures and functions, setting them apart from nerve tissue's unique role in controlling and relaying information within the nervous system.
