All of the following are true of cell junctions EXCEPT:

Some cell junctions fuse the inner surfaces of plasma membranes together.

During a lab, a student examines a tissue sample with a microscope. He sees several groups of irregularly shaped cells with central, darkly staining nuclei. The groups of cells resemble floor tiles or fish scales. He prepares to name the tissue, but the instructor asks him to state its function. What is the function of the tissue described?

Which cell junctions prevent epidermal cells from separating under tension?

adherens junctions

Flat sheets of flexible tissue found covering or lining large portions of the body are

called membranes.

The type of cell junction that prevents the contents of the stomach or urinary bladder from leaking into surrounding tissues is the:

tight junction.

Which of the following tissues provides the greatest protection from mechanical injury?

stratified squamous epithelium

Which of the following is true of glandular epithelia?

Their primary function is secretion.

Which type of membrane is found lining any body cavity that opens directly to the exterior?

B) mucous

A pathologist examines a thin slice of tissue with a microscope and notes numerous cells packed tightly together. No intercellular space or blood vessel is noted between cells, but the cells have polarity. One side of the cells opens into a cavity, and the other is attached to a thin layer of extracellular material. Several of the cells are in some stage of mitosis. Which primary tissue type does the pathologist see?

epithelial
