What myotome pattern includes knee flexion?

The myotome pattern associated with knee flexion is indeed B. S2, as this level of the spinal cord innervates the muscles responsible for this movement. The primary muscle involved in knee flexion is the hamstring group, which is primarily innervated by the sciatic nerve, with contributions from the S2 nerve root. This nerve root activates the muscles that contract to bend the knee.

Understanding myotomes is vital for assessing neurological function and identifying potential injuries. Each segment of the spinal cord corresponds with specific muscle groups, and S2 is integral in coordinating the knee flexion movement, commonly used in activities such as walking and running. This knowledge is important not only for athletic trainers but also for healthcare providers in both diagnostic and rehabilitative settings.
