suspendedCytoplasm: cytoplasm
2. plasma membrane: A selectively-permeable phospholipid bilayer forming the
boundary of the cells
3. Nucleus: A part of the cell containing DNA and RNA and responsible for growth
and reproduction
4. a minute cylindrical organelle near the nucleus in animal cells, occurring
in pairs and involved in the development of spindle fibers in cell division.:
centrioles
5. Ribosomes: site of protein synthesis
6. A system of membranes that is found in a cell's cytoplasm and that assists
in the production, processing, and transport of proteins and in the
production of lipids.: endoplasmic reticulum
7. Powerhouse of the cell, organelle that is the site of ATP (energy)
production: mitochondria
8. cell organelle filled with enzymes needed to break down certain materials
in the cell: lysosomes
9. a complex of vesicles and folded membranes within the cytoplasm of most
eukaryotic cells, A system of membranes that modifies and packages
proteins for export by the cell: golgi apparatus
10. decrease/schrinkage in cellular size for adaption: atrophy
11. increase in size of cells (organs) for adaption: hypertrophy
12. increase in number of cells for adapation: hyperplasia
13. reversible replacement of one mature cell type by another (epithelium
changes in smokers): metaplasia
14. abnormal changes in size, shape and organization of mature cells (can
lead to cervical cancer): dysplasia
15. increased copper accumulation in liver and NS (biliary defect);
AUTOSOMAL RECESSIVE s/s: hepatitis, neuro/MS--tremors muscle
incoord, behavioral change; Test: copper, ceruloplasmin, genetic test,
LFT, imaging.: Wilson's disease
, .
16. kayser-flescher rings in eyes: Wilson's disease
17. necrosis cardiac infarct (other tissues, not the brain); typically affects
kidney. Denaturation of proteins from gel to firm state: coagulative
18. necrosis of lipids and macrophages (develop granulomas)
TB/histoplasmosis
combo of coagulative and liquefactive. cells disintegrate /denature but debris

19 wet or dry necrosis that occurs from ischemia or bacteria; physical
injury/trauma.: gangrene
20. necrosis in pancreas/breast tissue: fat

38. Telemerase: An enzyme that catalyzes the lengthening of telomeres in
eukaryotic germ cells.
39 what characteristics of telemerase contribute to cancer: contribute to cancer
cell immortality; activity allowing a cell to replicate indefinitely; promoting synthesis
of telomere ends

infection and failure to thrive as a result of infections
44. how does inflammation play part in cancer development: contributes to
angiogenesis, limits apoptosis, initiates carcinogenesis, causes direct DNA
damage 45. CAR T cell therapy: T cells are removed from a patient and
modified so that they express CAR receptors specific to the patient's particular
cancer. The T cells, which can then recognize and kill the cancer cells, are
reintroduced into the patient. 46. genetically engineered immune cell; T-cell
