Question 5

Question 7

What is this called?

Answer 7

Dura mater - The first layer of the CNS

Question 8

Which is the one right?

Answer 8

Arachnoid matter - Middle layer of the CNS

Arachnoid mater is a thin opaque layer that sends wispy fibers inward to the pia mater. This created the spider web appearance that gives the arachnoid mater its name. The spinal arachnoid mater has a similar function and appearance to the cranial arachnoid mater. It is the middle of the three meningeal layers.
KEY FEATURES/ANATOMICAL RELATIONS
The arachnoid mater is located adjacent to the dura mater, separated from it by the potential subdural space. It is also separated from the spinal cord and pia mater by the presence of cerebrospinal fluid in the subarachnoid space. At the level of the second sacral vertebra, the arachnoid mater fuses with the dura mater.
