Both hyperplasia and hypertrophy is found in-
1.Pregnancy uterus
2.Cardiac muscle in cardiomegaly
3.Skeletal muscle in athelete
4.Breast development in puberty
Explanation
The massive physiological growth of the uterus during pregnancy is a good example of hormone induced increase in the size of an organ that results from both hypertrophy and hyperplasia.
This statement has been omitted from 8th/e of robbin’s and following two statements have been added :-
“The massive physiological growth of the uterus during pregnancy is a good example of hormone-induced increase in the size of an organ that results mainly from hypertrophy of muscle fibers” .“Hormonal hyperplasia is well illustrated by the proliferation of the glandular epithelium of the female breast at puberty and during pregnancy, usually accompanied by enlargement (hypertrophy) of the glandular epithelial cell” .
So, According to 8th of Robbins:-
Both hyperplasia and hypertrophy occurs in breast at puberty and during pregnancy.
Pregnant uterus mainly undergoes hypertrophy.
There are so many other books which have similar opinion and no one mention that breast undergoes both hypertrophy and hyperplasia at puberty.
Therefore, my opinion is against 8th edition of Robbin’s on this one and according to me the answer is pregnant uterus.
