Which term refers to the protective coverings around the brain and spinal cord?

• A. Aphasia
• B. Nephr/o
• C. Meninges
• D. Pneumonia

Answer: (C)

The protective coverings around the brain and spinal cord are called the meninges. These are three membranes—dura mater on the outside, arachnoid mater in the middle, and pia mater lining the brain and spinal cord—together they shield the nervous system, anchor it within the skull and vertebral column, and help contain the cerebrospinal fluid that cushions the CNS. Aphasia refers to a language impairment, Nephr/o is a root meaning kidney, and Pneumonia is an infection of the lungs, so none of those describe the coverings of the brain and spinal cord.
