1

A
The connections between the efferent motor neurone and the skeletal muscle
2
Q
What happens to acetylcholine after it reaches the nicotinic receptor?
A
It is broken down by acetylcholinesterase into acetate and chlorine which is taken back up by the neurones and recycle into new ACh into vesicles

5
Q
