Ep

Question 1

Epithelial cancers

Answer 1

Carcinomas

Question 2

Connective tissue or muscle cancer

Answer 2

Sarcomas

Question 3

Heamatopeatic

Answer 3

From bone marrow are leukimas

From lymphocytes lymphomas

Question 4

Neural cell cancer

Answer 4

Neuroblastomas

Question 5

Neural cell cancer from glial cell

Answer 5

Glioma

Question 6

single squamous

Answer 6

thin lining for gas exchange
found in alveoli
lining blood vessels

Question 7

stratified squamous epithelial has 2 main types

Answer 7

Keratinizing

and non k

Question 8

what is keratinizing

Answer 8

Epithelial cells which produce keratin and in doing so die becoming thicker, stronger, protective structures
Such cells lose their cellular organelles and nuclei, not visible under light microscopy.

Question 9

whats non k

Answer 9

Epithelial cells which do not undergo keratinisation. They retain their nuclei and organelles.
protect underlying tissues for various physical and chemical insults

Question 10

which part of the membrane are mitochdroa associated with

Answer 10

associated with extensive basal membrane infoldings, providing energy for active transport across the abundant membranes. The infoldings increase the amount of basal membrane that can pump ions and water.

Question 11

why are the mito there

Answer 11

providing energy for active transport across the abundant membranes.

Question 12

describe the strcuture of the basal membrane

Answer 12

The infoldings increase the amount of basal membrane that can pump ions and water.

Question 13

where are carriers normally found

Answer 13

found on the microvillous brush-border membranes

Question 14

what are microvilli

Answer 14

Microvilli are defined as plasma membrane projections of the villi.

Question 15

where are the secertoy granules found in exocrine cell

Answer 15

apical cytoplasm

near the top

Question 16

describe Epithelial turnover in the small intestine

Answer 16

new cells are constantly being produced by the crypt stem cells, to replace the cells constantly being lost from the villus tip.

Question 17

side effects of cancer chemo

Answer 17

results in inhibition of the proliferation of intestinal crypt cells
results in loss of the finger-like intestinal villi
gastro-intestinal disturbances that are side-effects of chemotherapy.
Cell loss from the villus tips continues as normal, but the failure to produce new cells to replace the lost cells results in a loss of tissue and the villi shorten.
