1
Q

What is a neuromascular junction?

A

a synapse between a motor neuron and muscle fiber

2
Q

What is the difference between a neuromuscular junction and a cholmergic synapse?

A
  • it has more receptors on the post-synaptic membrane - actiion potential is always generated in the post-synaptic membrane - will
    have a response
    -acetycholinesterase is found in pits on the post-synaptic membrane
  • receptors are called nicotinic cholinergic receptors
3
Q

What does sarco mean?

A

muscle

4
Q

What happens during neuromascular junction with the sarcolemma?

A

depolarisation will spread along the sarcolemma down the transverse tubules to the sarcoplasmic reticulum and this will release calcium ions
