multilayer in which only basal cells contact basal lamina and cells overlying basal layer are transformed during keratinization into horny “scales”

25
Q

where is stratified squamous keratinized epithelium found

A

epidermis

26
Q

describe transitional epithelium

A

multilayered, capable of changing shape with physiological transition

27
Q

where is transitional epithelium found

28
Q

2 parts of basement membrane

A

basal lamina and reticular lamina

29
Q

microvilli main function

A

absorption

30

what are stereocilia

A

very long non-motile microvilli

31
Q

on what cells do stereocilia occur

A

columnar epithelial cells

32
Q

function of stereocilia (2 functions)

A

increase the absorption surface area of cells and function as mechanoreceptors

33
Q

main function of glandular epithelium

A

secretion

mucus, enzymes, or hormones

35
Q

what are secretory cells of the gland are referred to as

A

parenchyma

36
Q

connective tissue, which supports the gland is called

A

stroma

37
Q

what does stroma do in addition to gland support

A

blood and nerve supply, lymphatic drainage

38
Q

name two classifications of glands

A

exocrine glands with ducts, and endocrine glands without ducts

39
Q

Life span of epithelial cells

A

varies from 3 days (intestinal cells) to 90 days (epidermis; usually 4-6 weeks)

40

monocyte

54
Q

what is hemopoiesis, erythropoiesis, leukopoiesis, thrombopoiesis

55
Q

where are blood cells formed in an adult

A

in the red bone marrow (long bones)

56
Q

basic steps of erythropoiesis

A

red bone marrow: begins as stem cell, growth, hemoglobin begins appearing in cell, nucleus expelled, new RBC enters circulation as reticulocyte

57
Q

name 3 different ways to classify exocrine glands

A

relationship to surface epithelium; number of layers of glandular cells in the secretory portion; shape of secretory end portion
