Twojoint
Twojoint is a term used in different contexts and does not refer to a single, universally recognized subject. In anatomy, two-joint, or biarticular, muscles cross two joints and play key roles in coordinating limb movement and transferring energy between joints. Examples include the gastrocnemius, which crosses the knee and ankle, and the biceps femoris, which crosses the hip and knee. Biarticular muscles enable efficient locomotion but can complicate movement during rapid changes in joint angles, and they are a focus of studies in biomechanics, rehabilitation, and sports science.
In music and entertainment, twojoint is a name adopted by artists or groups in various locales, often
Other uses of the term may occur in branding or product names that reference dual-function or dual-joint
