Which tissue type is indicated by the specimen and where is it found in the body?

• A. Dense irregular connective tissue - Ligaments
• B. Dense irregular connective tissue - Skin
• C. Mucoid connective tissue - Umbilical cord
• D. Dense regular connective tissue - Skin

Answer: (B)

Recognizing tissue type relies on fiber orientation and where it’s found. Dense irregular connective tissue features collagen fibers packed tightly but arranged in many directions, which lets it resist stretching from multiple angles. In the skin, the dermis is rich in this pattern, with fibroblasts interspersed among the interwoven collagen bundles. This contrasts with dense regular connective tissue, where fibers run parallel in one direction (as in tendons and ligaments), and with mucoid tissue (Like Wharton’s jelly in the umbilical cord), which has a loose, gelatinous appearance. So the specimen’s irregularly arranged collagen and its location in the skin point to dense irregular connective tissue found in the dermis.
