Neurotransmitters

Question 1

Classical NTs

Answer 1

Small, rapid acting, ex: Ach, Dopamine -ATP is odd one

Question 2

Neuropeptides

Answer 2

Large, slow-acting, may act as co-transmitters (with a classical NT)

Question 3

ATP NT classification

Answer 3

NT in brain-classical

Question 4

Unconventional NT

Answer 4

Break rules of things considered to be NTs (stored and released from vesicles via exocytosis)

Question 5

AMPA receptors

Answer 5

Very fast-sensory and cognition-let sodium in

Question 6

NMDA receptors

Answer 6

critical in memory-little slower than AMPA but long lasting

-let Na and Ca in

Question 7

NMDA and stroke

Answer 7

Overstimulated –> let in too much Ca –> kill neurons

Question 8

GABA

Answer 8

Main receptor in the brain for inhibition

Question 9

GABA a receptors

Answer 9

Cl channels

These are ion channels that let chloride in. Going to hyperpolarize the and make the cell more negative (makes it harder to have an action potential).

Question 10

GABA b receptors

Answer 10

open K channels and hyperpolarize the cell (make it more negative)) and is slower than GABA a

Question 11

Glycine

Answer 11

Main inhibitory transmitter in the spinal cord-lets in Cl

Question 12

Glutamate

Answer 12

Very fast and used for excitatory pathways

If inhibited CNS would shut down

Question 13

Norepinephrine

Answer 13

Monoamine which acts on alpha and beta receptors which are coupled to g-proteins and have broad actions
