Anatomy and Physiology I Test 3

The various types of epithelium are classified by

• the size and shape of cells.

• the shape of cells and number of cell layers.

• the number of cell layers and size of the cells.

• the size and location of cells.

• function and size of cells.

Which of the following categories of epithelium is based on cell shape?

• columnar

• keratinized

• stratified

• transitional

• simple

Stratified epithelium consists of

• multiple layers of cells.

• a single layer of cells.

• a single layer of cells that changes shape when the tissue is stretched.

• a multiple layer of cells that appears to change shape when the tissue is stretched.

• none of the above

Which type of epithelium has the following characteristics: multiple layers, squamous cell shape, dead outer layers of cells, and keratin presented in some cells?

• pseudostratified keratinized squamous epithelium

• simple cuboidal epithelium

• simple transitional epithelium

• moist stratified squamous epithelium

• stratified keratinized squamous epithelium

To determine that a type of epithelium is squamous, which of the following is most important?

• the number of cell layers

• the shape of most of the epithelial cells

• the shape of the most superficial epithelial cells

• the shape of the basal epithelial cells

• the shape of the basement membrane

Epithelial tissue that can stretch and change in shape when subjected to stress would be

• simple squamous.

• stratified squamous.

• simple columnar.

• transitional.

• pseudostratified columnar ciliated.

The three types of protein fibers found in connective tissue are

• hyaluronid acid, collagen, and reticular fibers

• proteoglycan, elastin, and reticular fibers

• collagen, elastic, and reticular fibers

• proteoglycan, elastin, and hyaluronic acid.

• chondronectin, osteonectin, fibronectin

Dense regular connective tissue would be found in

• a nerve.

• the brain.

• a ligament.

• a skull bone.

• a lymph node.

Reticular tissue is found in

• muscles.

• long bones.

• soft organs.

• the intestinal tissue.

• nerve tissue.

Intervertebral discs exhibit a great deal of strength because of the presence of thick bundles of

• elastin

• proteoglycan

• collagen

• hydroxyapatite

• calcium
