MOD: 3 LESSON 3: What hematopoietic elements are involved in the development of lymphomas and leukemias?

Question 1

Why is the hematopoietic system vulnerable to the development of neoplastic disease?

Answer 1

because of its high rate of cell division

Question 2

What two types of neoplasms affect hematopoietic maturation?

Answer 2

lymphomas;

leukemias

Question 3

What is the name of the cell, located in the bone marrow, that gives rise to erythrocytes and leukocytes?

Answer 3

pluripotent stem cell

Question 4

Match the following:
____ gives rise to cells that develop into red blood cells and platelets
____ gives rise to cells that develop into granulocytes and macrophages
____ gives rise to cells that develop into T lymphocytes and B lymphocytes

A. myeloid cell line
B. lymphoid cell line

Answer 4

Match the following:
A. myeloid cell line____ gives rise to cells that develop into red blood cells and platelets

A. myeloid cell line____ gives rise to cells that develop into granulocytes and macrophages

B. lymphoid cell line____ gives rise to cells that develop into T lymphocytes and B lymphocytes

Question 5

True / False - The normal maturation of both the myeloid and lymphoid cell lines leads to cells that are larger in size and have an increased nucleus: cytoplasm ratio.

Answer 5

False

Question 6

True / False - In leukemias and lymphomas, the development of a particular blood or lymph cell is arrested in an early developmental stage, leading to the accumulation and proliferation of immature cells.

Answer 6

True
