The Dominant Type of Extracellular Protein Fiber in Dense Connective

Question

The dominant type of extracellular protein fiber in dense connective tissue is
A) collagen.
B) elastin.
C) actin.
D) myosin.
E) connectin.

Accepted Answer

Collagen is the most abundant protein fiber in dense connective tissue. It provides tensile strength and is responsible for the tissue's resistance to stretching and tearing. Elastin is also present in some connective tissues but is not as dominant as collagen in dense connective tissue. Actin, myosin, and connectin are protein fibers found in muscle tissue, not connective tissue.
