GeneralClass 12AllAnswered 27 Mar 2026
Answer
The brain and spinal cord are primarily composed of nervous tissue (also called neural tissue). This specialized tissue consists of two main cell types: neurons (nerve cells) that transmit electrical signals, and neuroglia (supporting cells) that provide structural support, insulation, and nutrition. Nervous tissue in the central nervous system is organized into gray matter (cell bodies) and white matter (myelinated nerve fibers). This complex tissue enables processing, integration, and transmission of information throughout the body, controlling all voluntary and involuntary functions.
