Synapses Flashcards
0
Q
Nerve impulse
A
Electrical signal passed along the neurone
1
Q
Synapse
A
A junction between two nerve cells consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter
2
Q
Step 1
A
The nerve impulse travels along the axon to the synapse in the form of an electrical impulse
3
Q
Step 2
A
The vesicles containing neurotransmitter chemicals move towards the membrane
4
Q
Step 3
A
The neurotransmitter is emptied into the synapse
5
Q
Step 4
A
The neurotransmitter diffuses across the synapse
6
Q
Step 5
A
The neurotransmitter binds to the receptors on the surface of a dendrite (on the next neurone)
7
Q
Step 6
A
Binding of the neurotransmitter triggers a new nerve impulse
8
Q
Step 7
A
The nerve impulse travels along that dendrite towards the cell body and axon
