neurotransmitters

Question 1

NTS that can be both excitatory and inhibitory

Answer 1

Acetylcholine (ACh) and Substance P

Question 2

Amino Acid NTs

Answer 2

Glutamate, aspartate, GABA, Glycine

Question 3

Biogenic amines NTS (decarboxylated amino acids)

Answer 3

norepinephrine, epinephrine, dopamine, serotonin

Question 4

ATP & other purines NTs

Answer 4

ATP, ADP, AMP

Question 5

Large molecule NTs (neuropeptides)

Answer 5

Substance P

Question 6

Small molecule NTs

Answer 6

Nitric oxide, carbon monoxide

Question 7

The primary NT of the NMJ. Binds to excitatory ionotropic receptors at the NMJ, but can also bind to inhibitory metaboreceptors. IS broken down enzymatically by acetylcholinesterase

Answer 7

Acetylcholine

Question 8

Excitatory amino acid NT. Specifically, it is eliminated from the synaptic cleft by reuptake mechanisms

Answer 8

Glutamate

Question 9

Excitatory amino acid NT

Answer 9

Aspartate

Question 10

Inhibitory amino acid NT. Tends to bind to ionotropic, hyperpolarizing receptors that activate Cl- channels

Answer 10

GABA/Glycine

Question 11

Biogenic amine NT that is excitatory at the NMJ of cardiac and smooth muscle. Binds mostly to metabotropic receptors and is also a hormone

Answer 11

Norepinephrine

Question 12

Biogenic amine NT that binds mostly to metabotropic receptors and is also a hormone

Answer 12

Epinephrine

Question 13

Biogenic amine NTs of the CNS that are associated with a stunning range of function

Answer 13

Dopamine/Serotonin

Question 14

Purine NTs that are excitatory NTs of the CNS and PNS

Answer 14

ATP/ADP/AMP

Question 15

Neuropeptide NT that binds to metabotropic receptors to be either excitatory or inhibitory, depending on the type of ion channel. Involved in pain response

Answer 15

Substance P

Question 16

Excitatory, small molecule NTs that are gasses!! Cannot be stored in vesicles, so must be synthesized on demand and used immediately

Answer 16

Nitric oxide/Carbon monoxide
