Neuromascular Junction Flashcards
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
