1
Q

Electric transmission is the only mode of transmission between blank and blank muscle

A

Smooth, cardiac

2
Q

Gap junctions are specialized intercellular channels, channel proteins are called blank

A

Connexons

3
Q

Excitatory bouton has a thick blank unlike the inhibitory bouton

A

Postsynaptic density

4
Q

Cns has no blank which is unlike nmj

A

Extracellular matrix

5
Q

These proteins to vesicle recycling at the nerve terminal

A

Snare

6
Q

Snare that has synaptobrevin

A

V snare

7
Q

Syntaxin and snap 25 use this type of snare

A

T snare

8
Q

Calcium sensory involved in vesicle recycling

A

Synaptotagmin

9
Q

Fast nt act on blank channels

A

Ligand gated

10
Q

Slow nt blank ligand or voltage gated channels

A

Modulate

11
Q

Ach, gaba, and glycine receptors have blank subunits and n and c terminals are located blank

A

5, extracellularly

12
Q

Glutamine receptors have blank subunits and have n terminal located blank and c located blank

A

4, extracellularly, intracellularly

13
Q

Glutamatergic receptor types

A

Ampa, kainate, nmda

14
Q

Ampa are permeable to blank and blank which induces an EPP

A

Sodium, K

15
Q

Nmda receptors are permeable to these

A

Sodium, K, Calcium

16
Q

Nmda receptors trigger more blank intracellular signaling than ampa

A

Complicated

17
Q

Ionotropic glutamate receptors

A

Ampar, nmdar

18
Q

Metabotropic glutamate receptors

A

Group 1,2,3

19
Q

This blocks nmdar at resting membrane potential and is removed by depolarization

A

Magnesium

20
Q

Nmda receptorss are involved in blank because it is a synaptic coincidence detector

A

Learning/memory

21
Q

Excessive inflow of calcium through nmdar channels

A

Excitotoxicity

22
Q

Primary excitatory nt in the cns

A

Glutamate

23
Q

Glycinergic receptors are postsynaptic in motor centers of the blank and blank

A

Spinal cord, brainstem

24
Q

Gabaergic receptors are postsynaptic in the blank

A

Brain

25
Q

Gaba is permeable to blank

A

Chloride

26
Q

Glutamate receptors are concentrated at blank

A

Postsynatpic densities/ distal dendrites (like spines)

27
Q

Gaba receptors are concentrated at blank

A

Soma/proximal dendrites

28
Q

Electrical transmission is more prevalent in the cns before blank

A

Adulthood
