Quizplus · Accepted Answer

The tough layer of collagenous fibers that encloses the brain within the skull is called the dura mater. This layer serves as a protective barrier for the brain, preventing it from moving or getting damaged within the skull. Gray matter and white matter refer to the different types of cells found within the brain, and the myelin sheath is a fatty layer that surrounds nerve cells and helps to speed up neural transmission.
