Question 1

what is dale’s law

Answer 1

that each neuron specializes and synthesizes only one neuron (WRONG)

Question 2

what does it mean if a neuron is serotogenic

Answer 2

produces serotonin, does NOT mean that it has serotonin receptors or only responds to serotonin

Question 3

what does it mean if a neuron is dopamegenic

Answer 3

produces dopamine, does NOT mean that it has dopamine receptors or only responds to dopamine

Question 4

true or false: neurotransmitters are taken up by receptors/receiving neuron

Answer 4

FALSO

Question 5

what protiens bring vesicles carying neurotransmitters to cell membrain to be released into synapse

Answer 5

snare protiens

Question 6

what is clathrin and what does it do

Answer 6

protien that reuptakes/recycles vesicles (similar to transporter protiens and neurotransmitters)

Question 7

ligand (def)

Answer 7

something that binds to a receptor

made outside of the body (foreign)

Question 9

endogenous (def)

made inside the body

Answer 23

nigrostriatal, mesolimbic, and mesocortical pathways

Question 24

the BLANK (movement) pathway sends dopamine to BLANK and is associated with BLANK disease

Answer 24

nigrostriatal pathway sens dopamine to the midbrain and is associated with parkinsons disease

Question 25

the BLANK (drug reward) pathway sends dopamine to BLANK and is associated with BLANK SYMPTOMS of BLANK disease

Answer 25

the mesolimbic pathway sends dopamine to forebrain and is associated with positive symptoms of skitzofrenia

Question 26

the BLANK (executive functioning) pathway sends dopamine to BLANK and is associated with BLANK SYMPTOMS of BLANK disease

Answer 28

the nigrostriatal pathway starts at the substantia nigra and sends dopamine to the midbrain

Question 29

which dopamine pathway(s) starts at the ventral tegmental area and where does it go

Answer 29

the mesolimbic and mesocortical pathways start at the ventral tegmental area/midline/midbrain and send dopamine to the forebrain and prefrontal cortex respectivly
