Arachnoid mater

This tutorial by Matt from Kenhub explores the arachnoid mater, the middle layer of the meninges, which protects the central nervous system. It covers the structure and function of the arachnoid mater, including its role in cerebrospinal fluid circulation. The video explains the subdural and subarachnoid spaces, highlighting their significance in brain protection and CSF flow. Unique features of cranial arachnoid mater, such as subarachnoid cisterns and arachnoid villi, are discussed, emphasizing their roles in CSF absorption. The tutorial concludes with a promotion of Kenhub's anatomy learning resources.
