Neuroanatomy Part Deux
Settings
This is the second part. This will finish the rest of the nervous system notes for 214. As always, this is based off the lecture and class note. The creator of the quiz is not responsible for the accuracy of the contents of this quiz. Good Luck!

Secretes neurotransmitters that controls emotion
- D.
None of the above
- E.
All of the above
- 18.The inter most layer and lays directly on the external surface of the brain. 2) very vascular and serves as the bloodbrain barrier which keeps harmful stuff from the general circulation from reaching the brain and cerebral spinal fluid. 3)"means little mother"
