epithelial tissue

Question 1

4 basic type of tissues

Answer 1

epithelial
- surface
- glandular

connective
- ct proper
- specialized type

muscle
- skeletal
- cardiac
- smooth

nervous
- nervous tissue

Question 2

This ability of embryonic cells to differentiate into diverse cell types

Answer 2

cell differentiation

Question 3

Embryonic Origin of Epithelial Tissue

Answer 3

index card

Question 4

Composed of closely aggregated polyhedral cells with very little extracellular substance

Answer 4

epithelial tissue

• function:
  secretion
  filtration
  absorption
  protection

Question 5

Characteristics features of Epithelial Cells

Answer 5

index card

basal pole
- facing the basement membrane
(consists of basal lamina and lamina fibroreticularis)

apical pole
- facing the space

Question 6

modifications on the lateral surface is aka

Answer 6

intercellular junctions
Cell-to-cell attachments
Junctional complexes

Question 7

Refers to epithelial tissue that covers the external surfaces (covering epithelium) and lines the internal surfaces (lining epithelium).

Answer 7

surface epithelium

In simple, every cell is in direct contact with both the apical surface and the basal surface.
In stratification, only the cells in the bottom layer contact the basal surface and only the cells in the top layer contact the apical surface.

Question 8

why is function not one of the specialties in simple epithelium cell is

Answer 8

as it consists of a single layer and are usually very thin
hence, the functions are: absorption, secretion and filtration

Question 8

Organized to form the functional component of organs called glands that produce substances

Answer 8

glandular epithelium

Question 8

what us the main function of stratified epithelium

Answer 8

protection

• u can classify them on the basis of the shape of the cells in their most superficial layer

Question 8

basal cells and surface cells for
- stratified squamous epithelium
- transitional epithelium

Answer 8

• stratified squamous epithelium
  basal = cuboidal or columnar
  surface = squamous
• transitional epithelium
  basal = cuboidal or columnar
  surface = dome-shaped or squamous like
• if asked to describe the basement membrane, do not describe it as squamous as it will be named stratified squamous epithelium.

Question 9

small membrane- bound vesicles that generally stored the molecules to be secreted.

Answer 9

secretory granules

Question 10

nature of secretory cells secretion

Answer 10

mucous alveoli (acini)
serous alveoli (acini)
mixed alveoli (acini)

Question 11

mode of secretion

Answer 11

holocrine
apocrine
merocrine

Question 12

interpreting tissue sections

Answer 12

longitudinal
cross
oblique

Question 13

Several steps may destroy the tissues, producing minor structural abnormalities

Answer 13
