Is proliferation and hyperplasia the same?

Hyperplasia or “hypergenesis” refers to an increase in the number of cells within a given tissue as a result of cellular proliferation. Since hyperplasia refers to an increased number of cells, the cell appears normal in size, but can lead to an enlargement of an organ or tissue.

What is the medical term for hyperplasia?

Hypoplasia describes a lack of cell growth, but aplasia is a complete lack of an organ or tissue. People with hypoplasia will have a tissue or organ with too few cells. Aplasia means that there is no tissue or organ at all.

What is hyperplasia with example?

Types of hyperplasia ++ Physiologic hyperplasia: Occurs due to a normal stressor. For example, increase in the size of the breasts during pregnancy, increase in thickness of endometrium during menstrual cycle, and liver growth after partial resection.

What’s the difference between hyperplasia and hypertrophy?

From the differences, we can conclude that hyperplasia is the increase in the size of a tissue or an organ due to an increased number of cells while hypertrophy is an increase in the size of an organ due to the swelling of individual cells.

What does no atypia mean?

(ay-TIH-pee-uh) State of being not typical or normal.
