Which of the following tissues fills the spaces between the tissues and organs
of the body?
A. Basal lamina
B. CT
C. Epithelial tissue
D. Keratinized tissue
B. Connective tissue
Which of these epithelial layers is comprised of cells with nuclei that act as a
cushion against mechanical stress and wear?
A. Nonkeratinized layer
B. Keratinized layer
C. Extracellular ground layer
D. Collagen layer
A. Nonkeratinized layer
Epithelial cell junctions are cellular structures that can attach:
A. An epithelial cell to a neighboring epithelial cell
B. An epithelial cell to a basal lamina
C. An epithelial cell to elastin fibers
D. Both A and B
D. Both an epithelial cell to a neighboring epithelial
cell and an epithelial cell to a basal lamina
,The function of the cell junction is to:
Allow cells to bind together to function as a strong structural unit
A cell junction that connects an epithelial basal cell to the basal lamina is termed:
Hemidesmosome
In MOST places in the body, the epithelium meets the CT in a wavy, uneven
junction. T or F?
True
The deep extensions of epithelium that reach down into the CT are termed:
Epithelial ridges
CT is comprised of a gel-like substance, fibers and few
cells T or F?
True
The sulcular and JE are keratinized epithelial
tissues. T or F?
False
The epithelium that forms the base of the sulcus and joins the gingiva to the
tooth is called the:
JE
, In the JE, epithelial cell attaches to neighboring cells via:
Desmosomes
The JE attaches to the tooth surface via the:
Hemidesmosomes and the internal basal lamina
The JE attaches to the CT via:
Hemidesmosomes and the external basal lamina
Which of the following is NOT a function of the supragingival fiber bundles:
A. Brace the free gingiva against the tooth
B. Suspends the tooth in its bony socket
C. Allow the free gingiva to withstand the frictional fores
D. Connect adjacent teeth to one another
B. Suspends the tooth in its bony socket
An important function of the cementum of the tooth is to attach the
periodontal ligament fibers to the tooth.
T or F?
True
Alveolar bone is mineralized
CT. T or F?
True
