Nervous tissue is responsible for coordinating and controlling many body activities such as muscle contraction, environment awareness, emotions, memory, reasoning, speech, and many more. Nervous tissue is usually found in the brain, spinal cord, and nerves, and made up out of either two types of cells: neurons and glial cells or neuroglia which are also known as support cells that insulate and protect neurons(SEER Training, n.d.).
