Question: 1 / 400

What are the membranous linings present in the cranial cavity known as?

Peritoneum

Meninges

The membranous linings present in the cranial cavity are known as the meninges. The meninges serve several important functions, including providing a protective barrier for the brain, containing cerebrospinal fluid, and supporting the blood vessels that supply the brain. There are three layers of meninges: the dura mater, arachnoid mater, and pia mater, each having distinct structures and roles in safeguarding the central nervous system.

Peritoneum, on the other hand, refers to the lining of the abdominal cavity and is not associated with the cranial cavity. Synovial membranes are found in the cavities of synovial joints and aid in lubrication, while serous membranes line certain internal cavities but do not encompass the brain. Thus, the specific role and location of the meninges make them the correct choice in this context.
