DEEP EXPLANATIONS LATEST GRADED A+
Metaplastic cells are not better prepared to survive under stressful circumstances. True or False
Exam 1 - ANS-False
Hypertrophy can occur under normal and pathological conditions. True or False
Exam 1 - ANS-True
Which are true of the mitochondria? Select all that apply
Exam 1
1) It is involved in cellular respiration
2) They are found far from the site of energy consumption
3) They play a role in apoptosis
4) They control free radicals - ANS-It is involved in cellular respiration
They play a role in apoptosis
Which are true of the cell membrane? Select all that apply
Exam 1
1) Controls the transport of materials from the outside fluids to within
, 2 )The main structural component is made of proteins
3) Helps with the conduction of electrical currents in nerve and muscle cells
4) Aids in the regulation of cell growth and proliferation - ANS-Controls the transport of
materials from the outside fluids to within
Helps with the conduction of electrical currents in nerve and muscle cells
Aids in the regulation of cell growth and proliferation
Compare and contrast the two types of gangrenous necrosis
Exam 1 - ANS-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 - ANS-False Answer: cell differentiation
Cell differentiation is the process of increasing cell numbers by mitotic cell division. True or
False
Exam 2 - ANS-False, Answer: cell proliferation
What are two important properties that stem cells possess
Exam 2 - ANS-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 - ANS-progenitor or parent cells
