Synaptic Transmission

Question 1

The synaptic cleft

Answer 1

small small space between post/pre synaptic neurons

Question 2

Go steps of synapse

Answer 2

Action potential depolarizes Pre s membrane

Voltage gated Ca++ opens and enters axon terminal

Ca++ triggers Exotysis and neurotransmitter leave the cell

Neurotransmitters in the cleft binds and reacts with Post synaptic neuron

Question 3

Stop steps of synapse

Answer 3

Neurotransmitter may be degraded by enzymes
Taken back by presynaptic neuron
Diffuses away
Rapid endocytosis

Question 4

EPSP

Answer 4

involvemenrt

Question 5

IPSP

Question 6

chemical driving says go in, cell is more negative or an hyperpolarization

Answer 6

IPSP

Question 7

No Change

Question 8

Temporal Summation

Answer 8

Adding together of EPSP’s or IPSP’s generated by firing of the same presynaptic terminal at high frequency

Question 9

Spatial Summation

Answer 9

Adding together of EPSP’s or IPSP’s generated by firing of two or more presynaptic neurons simultaneously.

Question 10

IPSP works for my tricep and EPSP for my bicep

Answer 10

true

Question 11

Presynaptic facilitation and inhibitation

Question 12

If the combined signals of the EPSP and IPSPs reach - 55 then action potential is a go

Question 13

The further you are away, the less diffusion

Question 14

GPSP(Grand Postsynaptic Potential

Answer 14

summation of all
