what is exocytosis?

A

the process of neurotransmitter release

what does endogenous mean?

A

naturally occurring in the body

31
Q

what is a tripartite synapse?

A

synaptic transmission that depends on communication among three cells via gap junctions

32
Q

what is a metabotropic receptor?

A

a receptor associated with signal proteins and g-proteins

33
Q

what is an ionotropic receptor?

A

a receptor associated with ligand-activated ion channels

34
Q

what are voltage activated ion channels?

A

ion channels that open/close in response to changes in levels of membrane potential

35
Q

pressure to enter the cell comes from?

A

electrostatic pressure or random motion

36
Q

what happens when molecules bind to postsynaptic?

Q

What it the absolute refractory period?

A

where it is impossible to elicit a second action potential

41
Q

what is a relative refractory period?

A

a second action potential is possible but requires a higher level of depolarization
