Action potential.
00:02
Action potential, it is a kind of movement of ions that lead to the excitation of a particular tissue and this can be seen with regard to the neuronal cells and next to the neuronal cells apart from it it can also be exhibited by the skeletal muscles.
00:19
So these are the two important components in a human body which can generate or action potential and generating an action potential in turn denotes the excitation.
00:30
Stage.
00:31
So this is called as the excitation stage.
00:33
So this intern also contributes to a moment that is called as the contraction of the muscles.
00:39
So they in turn help in contraction and relaxation of the muscles which are present in close association with the neurons.
00:48
And one such muscles are the skeletal muscles.
00:51
So as soon as the skeletal muscle gets excited, then this excitation in turn it is coupled with another one process.
01:00
That is called as the open release of calcium ions.
01:04
Ca2 plus in turn denotes calcium ions.
01:06
The calcium ions in turn will be released from the sarcoplasmic criticalum return as sr.
01:13
And these are the ones which are present in the muscles.
01:16
And a small monomer of a muscle is called as the sarco lima.
01:21
So these all tend to take place in unit of the muscle tissue which is called as sarco lemma.
01:26
And as soon as the calcium ions have been released, they in turn.
01:30
Will interact with certain protein components that are present and these proton components can help in binding help in act in myocin contraction act in myocin movement and sliding of actin and myocin so this in turn help in contraction and relaxation process so this is how muscle contraction tend to take place in a muscle in the in the point of contact with a muscle with that of a neuron so here the one point that needs to be noted is that when a neuron has an action potential let's rate ap for action potential when a neuron has an action potential this intern will be transmitted to the skeletal muscles so as soon as it is transmitted to the skeletal muscles it will be transmitted in the form of neurotransmitters return as nts and these neurotransmitters intern will be released in a space on the contact of a neuron with that of the muscle so this space is called as the synaptic cleft...
