Question

Quizplus · Accepted Answer

The term "meninges" refers to the three layers of protective tissue that surround the brain and spinal cord, including the dura mater, arachnoid mater, and pia mater. These sheaths help cushion and protect the delicate nervous tissue, as well as help to contain and circulate cerebrospinal fluid. Choices B, C, and D are incorrect as glia refers to a type of supportive brain cell, ventricles are fluid-filled cavities within the brain, and "cerebrospinal sheaths" is not a commonly used term to refer to the meninges.
