Flashcards in Lec 6 - More Synaptic Transmission Deck (28):
1

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

Smooth, cardiac

2

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

Connexons

3

Excitatory bouton has a thick blank unlike the inhibitory bouton

Postsynaptic density

4

Cns has no blank which is unlike nmj

Extracellular matrix

5

These proteins to vesicle recycling at the nerve terminal

Snare

6

Snare that has synaptobrevin

V snare

7

Syntaxin and snap 25 use this type of snare

T snare

8

Calcium sensory involved in vesicle recycling

Synaptotagmin

9

Fast nt act on blank channels

Ligand gated

10

Slow nt blank ligand or voltage gated channels

Modulate

11

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

5, extracellularly

12

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

4, extracellularly, intracellularly

13

Glutamatergic receptor types

Ampa, kainate, nmda

14

Ampa are permeable to blank and blank which induces an EPP

Sodium, K

15

Nmda receptors are permeable to these

Sodium, K, Calcium

16

Nmda receptors trigger more blank intracellular signaling than ampa

Complicated

17

Ionotropic glutamate receptors

Ampar, nmdar

18

Metabotropic glutamate receptors

Group 1,2,3

19

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

Magnesium

20

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

Learning/memory

21

Excessive inflow of calcium through nmdar channels

Excitotoxicity

22

Primary excitatory nt in the cns

Glutamate

23

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

Spinal cord, brainstem

24

Gabaergic receptors are postsynaptic in the blank

Brain

25

Gaba is permeable to blank

Chloride

26

Glutamate receptors are concentrated at blank

Postsynatpic densities/ distal dendrites (like spines)

27

Gaba receptors are concentrated at blank

Soma/proximal dendrites

28

Electrical transmission is more prevalent in the cns before blank

Adulthood
