Hello all, so here the question is that if a thyroid hormone, so if a thyroid tumor is secreting an excess amount of calcitonin, then what would actually expected? so this is the question here.
00:21
So if it is secreting more than the excessive amount or more than the limited amount, what happens is the elevated level of osteoblast activity.
00:33
So this is the answer, elevated level of osteoblast activity.
00:49
So an increase in the level of calcitonin will decrease the osteoblast activity also.
00:55
So there is a decrease in the osteoblast activity, that means the amount of bond remodeling will decrease and the amount of bond generation get increases and it result in the decreased bond resolution and increased bond deposition.
01:14
So here it is, bond resolution will decrease, resolution will decrease and bond deposition will increase.
01:32
The next question is that in compact bonds, in compact bonds the osteoblast activity is mainly seen in or the osteoblast that are formed in which region? so this is the question here.
01:52
So in compact bond that means in small bonds we can see the osteoclast, osteoclast formation is mainly in the ossification zone of growth plate, ossification zone, growth plate.
02:20
So here we can see the osteoclast in compact bond and the other gene multi -nucleated osteoclast which break down the bond are occasionally found in the lacunae.
02:32
So here we can see it in the lacunae and otherwise this lacunae is termed as houshiep lacunae, it is also called houshiep lacunae.
02:50
And the third question that asked where the osteoclast can be seen in the long bonds? so where the osteoclast seen in long bonds? so these bond remodeling structures that seen in the long bonds are mainly along the matrix.
03:13
So it is along matrix or bond matrix.
03:19
It comprising of about 4 to 6 percentage of the total resident bond cell.
03:25
So it is about 4 to 6 percentage of total resident bond cell and they are largely found their bond forming function and this is mainly involved in the bond forming function.
03:43
And then the next question that a fracture in the end of the long bond would break in what? so this is the question here.
03:54
So the fourth one is that a fracture in the long bond will break in what? so this is the question.
04:05
So which present in a shaft of the bond? it would break in the diaphysis and this diaphysis is mainly seen at the end of the long bond or it can be considered as the end part of a long bond.
04:32
And then coming to the next question is that what will increase in the blood after bond resorption? so if the bond resorption or bond breakdown is happened, so this is the next question, bond breakdown is happened what will increase in the blood? so we know that bond is made up calcium phosphate and the blood will increase in the amount of calcium, calcium 2 plus will increase...
