What type of tissue forms the interspinous ligament?

What type of tissue forms the interspinous ligament?

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

Answer: (A)

The interspinous ligament is a thin, sheet-like bridge between adjacent spinous processes. It is formed by membranous fibrous connective tissue, meaning a delicate membrane of collagen fibers laid out in a slender, planar arrangement. This structure provides just enough stability to limit excessive separation during bending while preserving a bit of flexibility for the spine, which fits its role between the spinous processes. Hyaline cartilage would behave as a joint surface, adipose tissue would be fat rather than a binding structure, and dense irregular connective tissue would be thicker and less sheet-like, not matching the slender, membranous nature of this ligament.
