Portage Pathophysiology Module 2 Problem
Set Exam
Define Neoplasia
Correct Answers: means new growth
Define Neoplasm
Correct Answers: means the new growth itself
Define Proliferation
Correct Answers: process of cell division where new cell growth replaces old cells or when additional
cells are needed
Define Differentiation
Correct Answers: the process by which cells become more specialized with each mitotice division
Describe the cell cycle
Correct Answers: G1 to S phase to G2 to M phase
What are the 3 main groups of cells that proliferate?
Correct Answers: 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, such as blood, skin, and liver cells
3. undifferentiated stem cells that can enter the cell cycle and produce large numbers of progenitor
cells if needed
What are progenitor cells?
Correct Answers: biological cell that has a tendency to differentiate into a specific type of cell, but is
already more specific than a stem cell and is pushed to differentiate into its "target" cell
What are the benefits of the stem cell?
Correct Answers: self-renewal and potency meaning they can undergo numerous mitotic divisions
while maintaining an undifferentiated state and they vary in differentiation potential
What is the difference between malignant and benign tumors?
Correct Answers: Malignant tumors invade and destory tissue, growing rapidly and spreading to other
parts of the body
Benign tumors grow by expansion and remain localized to their site of origin, not capable of
metastising
What is polyp?
Correct Answers: growth that projects from a mucosal surface (like the intestine); malignant or benign
Metastasis
Correct Answers: The spread of cancer cells beyond their point of tissue origin
What are the 2 broad categories of malignant neoplasms?
