The Three Types of Protein Fibers in Connective Tissue Are

Question

The three types of protein fibers in connective tissue are
A) tendons, ligaments, and elastic ligaments.
B) loose, dense, and irregular.
C) cartilage, bone, and collagen.
D) collagen, reticular, and elastic.
E) polar, cellular, and permeable.

Accepted Answer

The three types of protein fibers in connective tissue are collagen, reticular, and elastic. Tendons and ligaments are types of dense connective tissue, and while elastic ligaments do exist, they are a specific type of connective tissue rather than a type of protein fiber. Loose, dense, and irregular are classifications of connective tissue but are not specifically types of protein fibers. Cartilage and bone are types of connective tissue, but they do not contain the three types of protein fibers found in other types of connective tissue. Polar, cellular, and permeable are not classifications or types of connective tissue or protein fibers.
