Aids in the regulation of cell growth and proliferation
Compare and contrast the two types of gangrenous necrosis
Exam 1 - CORECT ANSWER- Dry gangrene occurs when blood supply is slowly
reduced to an area. The area is dehydrated and becomes dark or black in color.
Commonly seen in patients with diabetes. It is not very painful, but tissues
eventually die.
Wet gangrene is caused by a sudden reduction in blood flow. The area is cold and
swollen, with no pulse. This can occur from trauma. Bacteria is involved and is
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 - CORECT ANSWER- False Answer: cell differentiation
Cell differentiation is the process of increasing cell numbers by mitotic cell
division. True or False
Exam 2 - CORECT ANSWER- False, Answer: cell proliferation
What are two important properties that stem cells possess
, Exam 2 - CORECT 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 - CORECT ANSWER- progenitor or parent cells
is a systemic treatment that enables drugs to reach the site of the tumor as well as
other distant sites
Exam 2 - CORECT ANSWER- chemotherapy
The profound weight loss and wasting of fat and tissue that accompany cancer is
known as
Exam 2 - CORECT ANSWER- cancer anorexia-cachexia syndrome
Explain the challenges of diagnosing autoimmune disorders - CORECT
ANSWER- There are about 80 autoimmune disorders identified, with many
overlapping presentations. Blood tests can be more generic and results are
imprecise. Markers can be elevated in the presecence of other diseases
The T cells that display the host's MHC antigens and T-cell receptors for a nonself-
antigen are allowed to mature, a process termed negative selection
True or False

Which lab value will typically be increased in a viral infection
Exam 3
