Dense irregular connective tissue has collagen fibers oriented in which pattern?

Dense irregular connective tissue has collagen fibers oriented in which pattern?

• A. Random multidirectional
• B. Parallel
• C. Circular
• D. Single direction

Answer: (A)

Dense irregular connective tissue has collagen fibers arranged in a random, multidirectional pattern. This organization lets the tissue resist tensile forces coming from many directions, which is important in skin dermis, organ capsules, and fascia. In contrast, tissues with parallel collagen fibers (dense regular connective tissue) are built to withstand pull in one direction, and a single-direction or circular pattern wouldn’t provide multi-directional strength.
