ciliated cells; secretion by cells of the glands, the
stomach, and the intestine; absorption by cells of
the intestine

A

Simple Columnar Epithelium

27
Q

Glands and some ducts, bronchioles of the lungs,
auditory tubes, uterus., uterine tubes, stomach,
intestines, gallbladder, bile ducts, and ventricles of
the brain

A

Simple Columnar Epithelium

28
Q

Single layer of cells; same cells are tall and thin and
reach the free surface, and others do not; the nuclei
of these cells are at different levels and appear
stratified; the cells are almost always ciliated and
are associated with goblet cells that secrete mucus
onto the free surface

A

Pseudostratified Columnar Epithelium

29
Q

Synthesize and secrete mucus onto the free
surface and move mucus that contains foreign
particles over the surface of the free surface and
from passages

A

Pseudostratified Columnar Epithelium

30
Q

Lining of nasal cavity, nasal sinuses, auditory tubes,
pharynx, trachea, and bronchi of lungs

A

Pseudostratified Columnar Epithelium

31
Q

Several layers of cells that are cuboidal in the basal
layer and progressively flattened toward the
surface; the epithelium can be nonkeratinized or
keratinized; in nonkeratinized stratified squamous
epithelium, the surface cells retain a nucleus and
cytoplasm of cells at the surface is replaced by a
protein called keratin, and cells are dead

A

Stratified Squamous Epithelium

32
Q

Protects against abrasion, forms a barrier against
infection, and reduces loss of water from the body

A

Stratified Squamous Epithelium

33
Q

Keratinized-outer layer of the skin; nonkeratinizedmouth, throat, larynx, esophagus, anus, vagina,
inferior urethra, and corneas

A

Stratified Squamous Epithelium

34
Q

from layers of cube-like cells intended to assist in
secretion, absorption and protection

A

Stratified Cuboidal Epithelium

35
Q

lining of the ducts of sweat glands, esophageal
glands and parts of the male urethra

A

Stratified Cuboidal Epithelium

36
Q

consists of more than one layer of epithelial cells,
but only the surface cells are columnar. The deeper
layers are irregular or cuboidal in shape

A

Stratified Columnar Epithelium

37
Q

stratified columnar epithelium is relatively rare. It is
found in the mammary gland ducts, the larynx, and
a portion of the male urethra
carries out secretion, protection, and some
absorption

A

Stratified Columnar Epithelium

38
Q

a special type of stratified epithelium that can be
greatly stretched
• In the unstretched state, transitional epithelium
consists of five or more layers of cuboidal or
columnar cells that often are dome-shaped at the
free surface
• stretched, the cells change to a low cuboidal or
squamous shape, and the number of cell layers
decreases

A

Transitional Epithelium

39
Q

Cell Connection
Cell Junction

A

Tight junctions
Adherens junctions
Desmosomes
Hemidesmodomes
Gap junctions

40
Q

fuse cells together tightly to prevent substances
from passing between the cells

A

Tight junction

41
Q

runs along micro laments to form a belt
or strap-like structure called an

A

adhesion belt

42
Q

plaque
a dense layer of proteins just inside the plasma
membrane

A

Adherens junctions

43
Q

• the plaque binds to intermediate laments and does
not form a belt
• they adhere at specific spots

A

Desmosomes

44
Q

resemble half of a desmosome. They do not adhere
adjacent cells but rather attach cells to membranes.

A

Hemidesmodomes

45
Q

form channels that allow ions and molecules to
pass between cells

A

Gap junctions

46
Q

ight junctions prevent the contents of these organs
from leaking out

A

Tight junction

47
Q

found in tissues with simple epithelia like those that
line the stomach, intestines, and urinary bladder

A

tight junction

48
Q

This arrangement resists separation even when
stretched

A

adherence junction

49
Q

permits cells in a tissue to communicate and
enables nerve or muscle impulses to spread rapidly
among cells

A

gap junction

50
Q

made of glandular epithelial cells that secretes
substances either in the surface or in the bloodstream.
These glandular epithelial cells form both endocrine and
exocrine glands

A

Glands

51
Q

ductless and secrete substance called hormones
directly into the interstitial fluid then to the blood

A

Endocrine gland

52
Q

secrete substances through tubes or ducts

A

Exocrine Gland

53
Q

includes thyroid gland, pituitary gland

A

Endocrine Gland

54
Q

sweat glands, salivary glands, and mammary
glands

A

exocrine gland

55
Q

Structure based on shape of ducts

A

Simple
Compound

56
Q

the duct ends directly into the
secretory portion

A

simple

57
Q

the duct ends into multiple secretory
branches

A

compound

58
Q

Based in Secretory units

A

Tubular
Acinar/Alveolar
straight
saclike structure

59
Q

Cells of the gland
produce secretions by active
transport or produce vesicles
that contain secretory
products, and the vesicles
empty their contents into the
duct through exocytosis

A

Merocrine gland

60
Q

Secretory products are stored in
the cell near the lumen of the duct. A
portion of the cell near the lumen
containing secretory products is
pinched off the cell and joins
secretions produced by a merocine
process.

A

Apocrine gland

61
Q

Secretory products are
stored in the cells of the gland.
Entire cells are shed by the
gland and become part of the
secretion. The lost cells are
replaced by other cells deeper in
the gland

A

Holocrine gland

62
Q

contains various cells, fibers and other substances.
It protects and supports the body and its organs. No wonder
it is one of the most abundant tissues.

A

connective tissue
