Okay, so we're supposed to be describing the events at the neuromuscular junction.
00:08
And we're supposed to talk about the events at the neuromuscular junction, excitation and coupling events, and the steps of the crossbridge cycle.
00:19
So let's first do the events at the neuromuscular junction.
00:40
There are seven of them.
00:43
So an ap travels down the axon.
01:03
And this goes to the axon terminal.
01:06
So to the axon terminal.
01:14
Number two is electrical gated calcium channels open.
01:35
And when they open, calcium enters the axon terminal.
01:56
The third event would be calcium causes the vesicles.
01:58
Calcium causes the vesicles to release ach into the synapticlft.
02:27
The fourth event is ach diffuses across the synaptic cliff and binds to its receptors on the muscle...
