What movement is associated with the L2 myotome?

The L2 myotome is primarily responsible for hip flexion, which is the movement where the hip is raised, reducing the angle between the thigh and the pelvis. The main muscle involved in this action is the iliopsoas, which receives its nerve supply from the lumbar plexus, particularly from the L2 and L3 nerve roots. This connection is crucial for understanding the functional anatomy related to hip mobility.

In contrast, the other movements listed are associated with different myotomes. For example, knee flexion is primarily mediated by the L4 and S1 myotomes, while ankle dorsiflexion corresponds to L4 and L5. Hip extension is mainly related to the S1 and S2 myotomes. This specificity highlights the importance of myotomes in determining muscle function and movement patterns in relation to different spinal nerve roots.
