Answer 16

Ceribum spinal fluid
Protects the spinal cord

Answer 17

Anterior and lateral horns of the gray matter

Question 18

Where are the cell bodies of peripheral sensory neurons

Answer 18

The dorsal root ganglion

Question 19

What is Pia matter

Answer 19

It is tender/soft mother
Denticulate ligaments because they look like a shark tooth it anchors and stablizeze
