meninges

Answer 26

dura, arachnoid, pia -PAD (pia being closer to brain tissue)

cerebrospinal fluid

Answer 27

provides a fluid cushion, surrounding the brain and spinal cord -circulated in the brain, ventricles (housed and produced)

Question 28

peripheral nervous system (PNS)

Answer 28

consists of nerve fibers and cell bodies outside the CNS -stuff that exists bones at some point and goes elsewhere
