Neuromuscular junctions are special junctions where muscles receive stimulus from the neurons.
00:11
So in this junction, the neurons release the neurotransmitters into the junction and cause the following changes.
00:20
First, the acetylcholine, that is acetylch, that is achth, will be realized.
00:30
Released from axon terminal from axon terminal into the synaptic cleft and this acetylcholine goes and binds to and it binds to receptor binds to the receptor molecules present on the receptor on the sarco lemma which is basically the the plasma membrane of the muscle cell.
01:05
Here the further changes includes starting an action potential.
01:12
An action potential is generated and thus the signal downhill process will start is generated and then this action potential will cause calcium ion c .a.
01:33
2 plus is to release is released from the er that is the endoplasmic reticulum of of muscle cell in response to the voltage chain, voltage change and then this ca2 plus binds to troponin.
02:04
Forming cross bridges.
02:07
So this forms the cross bridge between between the two main microtubules found in the muscles that is actin and the myocin...
