Steps Of Neuromuscular Junction:

Question 1

Step 1

Answer 1

Impulses arrives at the NMJ causing vesicles to fuse with the pre-synaptic membrane.

Question 2

Step 2

Answer 2

Release of ecetylcholine into gap (synapse/ synaptic cleft)

Question 3

Step 3

Answer 3

Acetylcholine binds to receptors on the muscle fibres membrane= depolarisation

Question 4

Step 4

Answer 4

Depolarisation travels down tumbles in muscle tissue.

Question 5

Step 5

Answer 5

Tubule depolarisation= Ca release from sarcoplasmic reticulum stores

Question 6

Step 6

Answer 6

CA++ binds to protein in the muscle leading to muscle contraction

Question 7

Step 7

Answer 7

Acetylcholinesterease in gap rapidly
