Which term means protein found in connective tissue?

• A. Coronary
• B. Collagen
• C. Conjunctivitis
• D. Costal

Answer: (B)

Collagen is the fibrous protein that forms the bulk of the connective tissue matrix, giving tissues their strength and structure. It’s produced by fibroblasts and assembles into fibers found in skin, tendons, ligaments, bone, and cartilage. Coronary relates to the heart’s vessels, conjunctivitis is inflammation of the eye’s conjunctiva, and costal means relating to the ribs—none describe a connective tissue protein. So collagen is the term that means the protein found in connective tissue.
