each other in the presence of Ca

A

34
Q

Each actin filament is connected by protein fibrin and villin

A

microvilli

35
Q

Each actin filament of microvilli is connected by

A

protein fibrin and villin

36
Q

a much less common type of apical process, best
seen on the absorptive epithelial cells lining the
male reproductive system
o increase the cells’ surface area, facilitating
absorption

A

stereocillia

37
Q

o Seen in Vas deferens and epididymis

A

stereocillia

38
Q

long, highly motile apical structures, larger than
microvilli, and containing internal arrays of
microtubules not microfilaments

A

cillia

39
Q

➢ - assembly of microtubules

A

Axoneme

40
Q

Epithelia can be divided into two main groups:

A

covering (or
lining) epithelia and secretory (glandular) epithelia

41
Q

The very thin surface cells of stratified squamous
epithelia can be “keratinized” (packed with keratin
filaments)

A
  • Stratified Squamous Keratinized Epithelium
42
Q

found mainly in the epidermis of skin, where it helps
prevent dehydration from the tissue

A
  • Stratified Squamous Keratinized Epithelium
43
Q

lines moist internal cavities (eg, mouth, esophagus,
and vagina) where water loss is not a problem.

A
  • Stratified Squamous Non-Keratinized Epithelium
44
Q

Rare in the body
o occurs in the excretory ducts of salivary and sweat
glands

A
  • Stratified Cuboidal
45
Q

seen in the conjunctiva lining the eyelids, where it is
both protective and mucus secreting

A
  • Stratified Columnar
46
Q

lines much of the urinary tract, extending from the
kidneys to the proximal part of the urethra,
o characterized by a superficial layer of large, dome
like cells sometimes called umbrella cells

A
  • Transitional Epithelium
    /urothelium
47
Q

tall, irregular cells all are attached to the basement
membrane but their nuclei are at different levels and
not all cells extend to the free surface, giving a
stratified appearance.

A

pseudostratified epithelium

48
Q

Contains goblet cells and cilia

A
  • Pseudostratified epithelium
49
Q

Epithelial cells that function mainly to produce and
secrete various macromolecules

A

glands

50
Q

may synthesize, store, and release proteins (eg, in
the pancreas), lipids (eg, adrenal, sebaceous
glands), or complexes

A

secretory cells

51
Q

o Composed of cells that secretes
substances/products

A

glandular epi

52
Q

2 types of glandular epi

A

exocrine and endocrine

53
Q

remain connected with the surface epithelium, the
connection forming the tubular ducts lined with
epithelium that deliver the secreted material where it
is used

A

exocrine g

54
Q

o lose the connection to their original epithelium and
therefore lack ducts.

A

endocrine glands

55
Q

Secretory portions can be ???? (either short or long and
coiled) or ??? (rounded and saclike); either type of secretory
unit may be branched, even if the duct is not branched

A

Secretory portions can be tubular (either short or long and
coiled) or acinar (rounded and saclike); either type of secretory
unit may be branched, even if the duct is not branched

56
Q

the most common method of protein or glycoprotein
secretion and involves typical exocytosis from
membrane-bound vesicles or secretory granules.

A

MEROCRINE SECRETION

57
Q

EXOCRINE SECRETION TYPES

A

MEROCRINE SECRETION, HOLOCRINE SECRETION, APOCRINE SECRETION

HOMEPO

58
Q

cell disruption that releases the product and cell
debris into the gland’s lumen. This is best seen in
the sebaceous glands producing lipid rich material in
skin

A

HOLOCRINE SECRETION

59
Q

product accumulates at the cells’ apical ends,
portions of which are then extruded to release the
product together with small amounts of cytoplasm
and cell membrane. Lipid droplets are

A

APOCRINE SECRETION

60
Q

ENDOCRINE SIGNAL TYPES

A

PARACRINE AND AUTOCRINE

61
Q

ENDOCRINE SIGNALS ARE RENEWED CVUA

A

MITOSIS

62
Q

provides a matrix that supports and physically
connects other tissues and cells together to form the
organs of the body
