BIOD 331 Pathophysiology Module 2 Exam Review Questions and 100% Correct
Answers 2026/27 Update – Portage Learning
Question 1
pts
Define neoplasia and neoplasm:
Your Answer:
A neoplasia is a new growth and is referred to as a neoplasm
Neoplasia is a disorder of altered cell differentiation and growth. Neoplasm is the “new growth.”
Question 2
pts
Define proliferation and differentiation:
Your Answer:
Proliferation is an adaptive process for new cell growth to replace old cells through cell division.
Differentiation is the process by which cells become more specialized with each mitotic division
Proliferation, a process of cell division, is an adaptive process for new cell growth to replace old
cells or when additional cells are needed. Differentiation is the process in which cells become
more specialized with each mitotic division.
Be familiar with the cell cycle (figure 2.1).

, Question 3
pts
What are the 3 main groups of cells that proliferate?
Your Answer:
(1) well-differentiated neurons and cells of skeletal and cardiac muscles that rarely divide and reproduce
(2) progenitor or parent cells that continue to divide and reproduce, like blood, skin, and liver cells
(3) undifferentiated stem cells that can enter the cell cycle and produce large number of progenitor cells
if needed
(1) well-differentiated neurons and cells of skeletal and cardiac muscles that rarely divide and
reproduce; (2) progenitor or parent cells that continue to divide and reproduce, like blood, skin,
and liver cells; (3) undifferentiated stem cells that can enter the cell cycle and produce large
number of progenitor cells if needed.
Question 4
pts
What are progenitor cells?
Your Answer:
parent cells of the same genetic lineage
The more specialized cells are unable to divide, so these cell populations rely on progenitor or
parent cells of the same lineage that have not yet differentiated to the extent that they have lost
their ability to divide. They have enough differentiation so the daughter cells are limited to the
same cell line, but not quite differentiated enough to prohibit active proliferation.
Question 5
pts
What are the benefits of the stem cell?
Your Answer:
Stem cells have the ability to enter the cell cycle and produce large numbers of progenitor cells as they
remain incompletely differentiated and dormant until they are needed.
Stem cells remain dormant until they are needed. When needed, they can divide, produce other
stem cells, and carry out the functions of the differentiated cell. Two important properties that
stem cells possess are self-renewal and potency. Self-renewal means the stem cell can undergo
numerous mitotic divisions while maintaining an undifferentiated state. Potency describes the
differentiation potential of stem cells.
