Question

Quizplus · Accepted Answer

The arachnoid mater is a delicate, cobweb-like, meningeal layer that is located between the dura mater and the pia mater. It lacks blood vessels, but it contains thin, spiderweb-like projections that attach it to the underlying pia mater, creating a subarachnoid space filled with cerebrospinal fluid (CSF).
