Fibers, cells and ground substance.
- B.
Neurons and neuroglial cells.
- C.
Actin and myosin.
- D.
Sheets of cells that cover and line other tissues.
- E.
Dendrites, cartilage, perikaryon.
- 4.Epithelial tissue can function in the manufacture of secretions and excretions.
- A.
True
- B.
False
- 5.What two surface do epithelial cells contain?
- A.
Rough and smooth.
- B.
Granular and jagged.
- C.
Basement membrane and brush border.
- D.
Apical and basal.
- E.
Kerotinized and stratified.
- 6.The apical surface of epithelial tissue faces the underlying connective tissue and the basal surface faces the lumen.
- A.
True
- B.
False
- 7.What do epithelial cells rely on to provide oxygen and nutrients and why?
- A.
Rely on osmosis to absorbs nutrients from the external source due to loose connective cellular matrixs.
- B.
Rely on underlying connective tissue and are vascular.
- C.
Rely on goblet cells to provide nutrients because of the pinocytosis actions of the goblet cells.
- D.
Transport RNA delivers the nutrients to the cells because Epithelial cells lack ATP to produce their own nutrition.
- E.
Rely on underlying connective tissue and are avascular.

- 9.Some epithelia lack nerves, but most are ________ to provide sensory input.
- A.
Polar.
- B.
Stable.
- C.
Columnar.
- D.
Innervated.
- E.
Filtered.

- A.
Cilia.
- B.
Matrix-filled channels.
- C.
Flagella.
- D.
Oviduct.
- E.
Gap junctions.
- 11.The passages between cells act as distribution routes and elimination routes for waste.
- A.
True.

Electrostatic attraction.
- C.
Build up of polar molecules outside the cell.
- D.
A gluey substance called Mucin.
- E.
The fusion of the outermost layers of the plasma membranes of adjoining cells.

- A.
Keratin.
- B.
Desmosome.
- C.
Cartilage.
- D.
Bone Marrow.

- A.
True.
- B.
False.
- 16.Connexons link cells connected by gap junctions and are tubular channel proteins.
- A.
True.
- B.
False.
- 17.What is the basement membrane?
- A.
The foundation of the epithelial cell.
- B.
The seperation between upper and lower portions of the matrix.
- C.
A protective layer that is constantly sloughing off.
- D.
Increases the surface area of a cell.
- E.
A protective, waterproof substance.
