Answer

The primary function of nervous tissue is to transmit and process information throughout the body. It allows for communication between different parts of the body, enabling responses to stimuli. The two main types of cells are neurons and neuroglia (or glial cells). Neurons are the functional units that transmit nerve impulses (electrical signals). Neuroglia are supporting cells that provide structural and metabolic support to neurons, insulate them, and maintain the chemical environment.
