Dense connective tissue proper includes which two types?

• A. Dense regular and Dense irregular
• B. Bone and Cartilage
• C. Blood
• D. Lymph

Answer: (A)

Dense connective tissue proper is defined by a high density of collagen fibers with relatively little ground substance and few cells, giving it strong tensile strength. The two forms differ in how those collagen fibers are arranged: dense regular has fibers aligned in the same direction, providing very strong unidirectional support as seen in tendons and ligaments; dense irregular has fibers woven in many directions, offering multidirectional strength as found in the dermis and organ capsules. This is distinct from bone and cartilage, which are supporting connective tissues with mineralized or semi-ribbed matrices, and from blood or lymph, which are fluid connective tissues.
