What is the membrane between bones called?

• A. Subclavian Groove
• B. Malleolar
• C. Interosseous Membrane
• D. Supraacetabular Groove

Answer: (C)

Interosseous membrane is a fibrous sheet that binds two adjacent long bones along their shafts. It’s strongest in dense connective tissue and sits between bones like the radius and ulna or the tibia and fibula. This membrane stabilizes the two bones, helps distribute load across the forearm or leg, and provides attachment sites for muscles, while still allowing subtle movement between compartments. The other terms describe specific bone landmarks or grooves (malleolar region, a groove name, or a groove near the acetabulum), not a connective tissue sheet linking bones. So the membrane between bones is the interosseous membrane.
