[movement]

Answer 1

• activates skeletal muscles and carries out voluntary movements

transmission blocked by anesthesia/poisons, resulting in paralysis

Question 2

aceytlcholine (ACh)

memory

Answer 2

memory formation and learning

Question 3

aceytlcholine (ACh)

deficit

Answer 3

• alzheimer’s disease
• paralysis/limited mobility

Question 4

aceytlcholine (ACh)

surplus

Answer 4

violent muscle contractions/spasms

Question 5

Question 8

dopamine

deficit

Answer 8

parkinson’s disease: muscle spasms/loss of motor control

surplus

Answer 9

Question 10

norepinephrine

Question 13

gamma aminobutyric acid (GABA)

Answer 13

• inhibitory neurotransmitter
• slows things down
• reduce neu. action potential firing

Question 14

agonist

Answer 14

• substance that activates receptors for certain neurotransmitters
• strengthens effect of neurotransmitter

Question 15

agonist

examples

Answer 15

heroin, oxycodone, methadone, merophins mimic endorphins

Question 16

antagonist

Answer 16

substances that attaches to neurotransmitter receptors & inhibits them

Question 17

antagonist
