Hello student here the question is given and the question is regarding the wall of hearth.
00:07
So we have to label these structure and these are the wall of hearth is given.
00:13
So we know this wall of hearth have three layers mainly.
00:17
So if we divide it into this then it is the three layers.
00:20
So outer one and the second one is the middle layer and third one is the inner layer.
00:29
So if we talk about this outer one so it is called as epicardium and this epicardium is further divided into the fibrous layer and the serous pericardium.
00:47
And the middle one is known as myocardium and the inner one is called as endocardium.
00:59
So these are the layers which are found in the wall of hearth.
01:03
So if we look at this structure so from here it is the outermost.
01:08
So outermost one is the layer of this epicardium which is the fibrous one.
01:14
So this one is fibrous.
01:19
So here this fibrous pericardium is the one and the second layer which is the parietal layer of the serous.
01:28
So this serous can also further divided into this parietal as well as the visceral.
01:34
So these parietal and visceral is the two different part of the serous layer...
