Question 1 Not yet graded / 0 pts
Define neoplasia and neoplasm:
Your Answer:
neoplasia is the process of new growth
neoplasm is a new growth that lacks the control of typical proliferation and differentiation (can be benign or malignant
Neoplasia is a disorder of altered cell differentiation and growth. Neoplasm is the “new growth.”
Question 2 Not yet graded / 0 pts
Define proliferation and differentiation:
Your Answer:
proliferation : a process of cell division, is an adaptive process for new cell growth to replace old cells or when more cells are needed
Differentiation: when a cell becomes 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 Not yet graded / 0 pts
What are the 3 main groups of cells that proliferate?
Your Answer:
1: well differentiated neurons and cells of the skeletal and cardiac muscles that rarely divide
2: progenitor or parent cells that continue to divide or produce such as blood, skin, and liver cells
3: undifferentiated stem cells that can enter the cell cycle and produce large # 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 Not yet graded / 0 pts
What are progenitor cells?
Your Answer:
they are parent cells that are not yet differentiated to the same extent as mature specialized cells yet differentiated enough to give rise to
daughter cells of the same 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 Not yet graded / 0 pts
What are the benefits of the stem cell?
Your Answer:
they remain dormant until they are needed. when needed they begin to divide, producing stem cells and cells capable of carrying out the
functions of the needed differentiated cells. self renewal and potency
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.
Know the difference in terminology of benign and malignant tumors according to tissue types. Refer to table 2.2.
Question 6 Not yet graded / 0 pts
What is a polyp?
Your Answer:
is a growth that projects from the mucosal surface. can be benign or malignant.
A polyp is a growth that projects from a mucosal surface, such as the intestine. A polyp can be benign or malignant.
Compare and contrast benign and malignant tumors:
Refer to table 2.2
