1

Death of an axon distal to the site of injury after an axon is transected

Anterograde/Orthograde degeneration
(Wallerian degeneration)

2

Acetylcholine

nucleus basalis of Meynert

3

Dopamine

substantia nigra pars compacta, ventral tegmental area

4

All neutrotransmitters are reuptaked before being degenerated except

acetylcholine

5

Norepinephrine

locus ceruleus in the pons

6

Serotonin

median raphe of brainstem

7

Neurotransmitter that is not preformed and stored in vesicles

nitric oxide

Retrograde amensia

thalamus

9

Anterograde amnesia

hippocampus

10

True or false: hippocampus stores memory

Hippocampus does not store memory

Shivering (heat conservation)

posterior hypothalamus

17

Reward center

medial forebrain bundle

18

Punishment center

central gray area around cerebral aqueduct

Social inhibition

amygdala

20

Melatonin increases in daylight or darkness?

darkness

21

cerebral autoregulation

60-140 mmHg

22

Rubrospinal tract

stimulation of flexors
inhibition of extensors
