Neoplasms

Question 1

Telemerase

Answer 1

protect the ends of chromosomes and shortens w each cell division

Question 2

nucleus

Answer 2

contains DNA which controls cells, enclosed by nuclear membrane

Question 3

cytoplasm

Answer 3

contains all nutrients, proteins, and glucose.

Question 4

Mutation

Answer 4

If DNA is altered in the parent cell, the mutation is passed onto the daughter cells.

Question 5

What cells have rapid mitosis

Answer 5

epithelial cells, leukocytes

Question 6

what cells do not go through mitosis

Answer 6

neurons, cardiac muscle

Question 7

Benign suffix

Answer 7

OMA.

Question 8

Malignant epithelial suffix

Answer 8

carcinoma

Question 9

malignant connective

Answer 9

sarcoma

Question 10

Benign tumour

Answer 10

Undifferentiated cells that usually reproduce at a higher than normal rate. Encapsulated, expands but does not spread.

Question 11

Malignant tumors

Answer 11

Undifferentiated, nonfunctional cells that do not appear organized. Reproduce rapidly. Infiltrate and spread to surrounding tissue.

Question 12

Pathophysiology of tumor

Answer 12

Normal organization, growth inhibition, contact controls, and cell–cell communication are absent. Cell membranes, including surface antigens, are altered. The expanding mass compresses nearby blood vessels, leading to necrosis and an area of inflammation around the tumor

Question 13

Chemo drugs

Answer 13

Adriamycin (doxorubicin), an antitumor antibiotic that binds DNA and inhibits synthesis of nucleic acids, acting primarily on cells in the S phase (DNA synthesis) but with some activity in other stages (e.g., altering the cell
membrane)
* Bleomycin, also an antitumor antibiotic that inhibits DNA synthesis
* Vinblastine, a cell-cycle–specific antimitotic drug that acts on cells in the M stage
(mitosis)
* Dacarbazine, an alkylating agent nonspecific drug acting at several points in the
cycle
