interosseous membrane

The interosseous membrane is a strong, fibrous sheet of connective tissue that connects the shafts of two parallel bones in the forearm (radius and ulna) or leg (tibia and fibula). It helps stabilize the bones, allowing them to work together while maintaining proper spacing. This membrane also acts as a site for muscle attachment and distributes forces transmitted through the limbs during movement, providing support and flexibility. Overall, it plays a crucial role in the structural integrity and functional movement of the limbs.
