What does gray tissue in the nervous system indicate?

Gray tissue in the nervous system is primarily associated with a high concentration of cell bodies, which are the main components of neurons. This gray matter is rich in neuronal cell bodies, dendrites, and unmyelinated axons, which contribute to processing and neuronal functions. It plays a critical role in various brain functions, including muscle control, sensory perception, memory, and emotions.

The presence of cell bodies contrasts with white matter, which contains a high concentration of myelinated axons that facilitate communication between different brain regions. The relationship between the structure of gray matter and its function is fundamental to understanding how the nervous system operates and processes information.
