Without having a strong glute medius your knees might cave in during the squat, which would increase the amount of shear force at the knee joint. The muscles of the back can be divided into three groups superficial, intermediate and deep: Superficial associated with movements of the shoulder. In the forearm, it is divided into a superficial branch (primarily sensory) and a deep branch (primarily motor). Once the nerve passes through the intervertebral foramen, it branches; each branch has both motor and sensory fibers. Read here. Any damage to the spinal cord can result in a loss of sensory and motor function below the level of injury. An antagonist stabilizer will help maintain the postural alignment of specific joints.
