Which of the following descriptions best describe a squamous-shaped cell?

A flattened, scale-like cell

Which of the following exocrine glands stores its secretion until the gland ruptures?

A holocrine gland

Match the following major tissue type with its description: Epithelium.

Avascular; associated with a basement membrane; apical and basal surfaces; great powers of regeneration; sparse extracellular matrix

Match the following epithelial tissue with a body location where it can be found: Keratinized stratified squamous.

Epidermis of skin

The basement membrane is located between which of the following tissue types?

Epithelial and connective tissue

Which of the following is true with regards to epithelia?

Epithelial cells have an apical surface and a basal surface which differ in both structure and function.

__________ are important and common unicellular exocrine glands.

Goblet cells

Match the following epithelial tissue with a body location where it can be found: Pseudostratified ciliated columnar.

Lines most of the upper respiratory tract

Match the following epithelial tissue with a body location where it can be found: Transitional.

Lines the urinary bladder

Match the following epithelial tissue with its location: Stratified cuboidal

Mostly found in the ducts of some of the larger glands (sweat glands, mammary glands)

Match the following type of epithelium with its description: Transitional.

Multiple layers of cells with apical cells varying in appearance depending on the degree of stretch

Which of the following does not correctly describe stratified columnar epithelium?

Present in either keratinized or nonkeratinized varieties

Match the following epithelium with its function(s): Stratified squamous.

Protection from wear and tear

You observe a tissue that has cells of varying heights. At first glance, it appears that the tissue has multiple cell layers, but upon closer investigation, you see that all of the cells attach to the same basement membrane. What classification would you give to this epithelial tissue?

Pseudostratified columnar epithelium

Match the following epithelial tissue with its function: Pseudostratified columnar.

Secrete substances, particularly mucus; propulsion of mucus by ciliary action

Match the following epithelium with its function(s): Simple cuboidal.

Secretion and absorption

Mucus that protects your stomach lining is secreted by which type of epithelial cell?

Simple columnar

Which of the following tissues lines the majority of the digestive tract?

Simple columnar

Which of the following epithelial tissue types is best adapted for the rapid transport of materials across its membranes?

Simple squamous

Match the following epithelial tissue with its structure: Simple cuboidal.

Single layer of cubelike cells with large, spherical central nuclei

Match the following epithelium with its function(s): Transitional.

Stretching

Match the following specialized characteristic of epithelium with the appropriate description or example: Polarity.

Tissue with a free apical surface

Why are histological sections stained?

To enhance contrast.

What is the role of an exocrine gland?

To secrete substances onto body surfaces or into body cavities.

Match the following epithelial tissue with a body location where it can be found: Simple cuboidal.

Walls of smallest ducts of glands and kidney tubules

Match the following epithelial tissue with a body location where it can be found: Simple squamous.

Walls of the air sacs of the lungs and lining blood vessels
