Question

BlackTom AI · Accepted Answer

Consider the question about the meninges and identify which layer is described as the most delicate, composed of elastic and collagen fibers.
Option 1: pia mater. This option points to the inner, delicate membrane that adheres closely to brain and spinal cord surfaces; it is known for its fine, vascular, and highly delicate nature, containing small collagens and elastic components.
Option 2: falx cerebri. This is a dural fold that partitions the cerebral hemispheres; being a dural structure, it is thick and tough rather than delicate, so it does not match the description of the loosest, most delicate layer.
Option 3: arachnoid mater. The arachnoid is the middle meninx and is more fibrous than the pia but still not the most delicate. It sits between the dura and the subarachnoid space and provides a barrier rather than a delicate, vascular surface.
Option 4: dura mater. This is the outermost and toughest meningeal layer, forming protective enclosures and dural folds; its toughness is in direct opposition to the notion of a delicate layer described in the prompt.
In summary, the description of a finely composed layer with elastic and collagen fibers, closely investing the brain and spinal cord, best matches the innermost and most delicate meninx, while the other options refer to tougher, outer, or intermediate layers that do not fit the given criteria.
