They are involved in apoptosis
Which of the following are true of the cell membrane? Choose all correct
Exam 1
1) It regulates transport of materials from the external fluids into inside
2 )The primary structural constituent is composed of proteins
3) Assists with the propagation of electrical impulses along the nerve and muscle cells
4) Assists in the regulation of cell growth and replication - ANSWER Governs the
, movement of materials from the external fluids to the inside

Compare and contrast the two types of gangrenous necrosis
Exam 1 - ANSWER Dry gangrene occurs when the blood supply is slowly reduced to an
area. The area dehydrates and become dark or black in color. Commonly seen in
patients with diabetes. It is not real painful however, tissues will eventually die from lack

very painful. It has the appearance of pus because it looks wet. There is also a foul smell
Cell proliferation is the process in which proliferating cells become more specialized
cell types. True or False
Exam 2 - ANSWER False Answer: cell differentiation
Cell differentiation is the process of increasing cell numbers by mitotic cell division.
True or False
Exam 2 - ANSWER False, Answer: cell proliferation
What are two important properties that stem cells possess
Exam 2 - ANSWER Potency and self-renewal
These are cells of the same lineage that have not yet differentiated to the extent that
they have lost their ability to divide
Exam 2 - ANSWER progenitor or parent cells
is a systemic treatment that allows drugs to reach the site of the tumor as well as other
distant sites
