Verified step by step guidance

Step 1: Understand the squat movement pattern. A squat involves lowering the body by bending the legs at the hips, knees, and ankles, and then returning to a standing position. This movement primarily engages the lower body joints.

Step 2: Identify the joints involved in the squat. The hip joint allows flexion and extension of the thighs, the knee joint facilitates bending and straightening of the legs, and the ankle joint enables dorsiflexion and plantarflexion of the feet.

Step 3: Eliminate irrelevant joints. Temporomandibular and sacroiliac joints are not involved in the squat movement. Similarly, vertebral and costovertebral joints are primarily involved in spinal and rib movements, not lower body mechanics. Shoulder, elbow, and wrist joints are upper body joints and are not central to the squat.

Step 4: Focus on the correct joints. The hip, knee, and ankle joints are the primary joints responsible for the squat movement pattern, as they allow the necessary range of motion for lowering and raising the body.

Step 5: Relate the movement to anatomy. During a squat, the hip joint undergoes flexion and extension, the knee joint performs flexion and extension, and the ankle joint engages in dorsiflexion and plantarflexion. These coordinated movements enable the squat pattern.
