Quizplus · Accepted Answer

Only in the presence of pathologic processes,notably epidural and subdural hemorrhages,do the potential spaces of the arachnoid layer become evident.It is semitransparent and weblike in appearance,hence its name.From the arachnoid layer come strands of collagenous connective tissue called trabeculae that extend down to the pia mater,forming a subarachnoid space.The arachnoid is a thin,delicate membrane.Beneath,and continuous with,the dura is the arachnoid layer.The spaces between the dura and the skull and between the dura mater and the arachnoid are potential spaces.
