Which statement best describes the histological composition of the interspinous ligament?

• A. Membranous fibrous connective tissue
• B. Hyaline cartilage
• C. Bone tissue
• D. Adipose tissue

Answer: (A)

Ligaments are built mainly from fibrous connective tissue rich in collagen, providing tensile strength to resist pulling forces. The interspinous ligament lies between adjacent spinous processes along the back of the spine and is best described histologically as a thin sheet of membranous fibrous connective tissue. This means it’s composed chiefly of collagen fibers with scattered fibroblasts, forming a flexible, tensile structure rather than a cartilaginous or bony tissue. Hyaline cartilage would be found at joint surfaces, bone tissue in bones, and adipose tissue in fat stores, none of which characterize the interspinous ligament.
