| Function | The first cervical vertebra that supports the skull. Allows nodding movements (flexion and extension) of the head at the atlanto-occipital joint. | The largest and most powerful muscle in the body. Primary extensor and lateral rotator of the hip. Essential for standing from a seated position, climbing stairs, running, and maintaining upright … |
| Clinical Significance | Jefferson fractures (burst fractures of the atlas) result from axial loading. Atlanto-occipital dislocation is usually fatal. Congenital anomalies include atlas assimilation (occipitalization). | Gluteus maximus weakness (Trendelenburg gait) results from inferior gluteal nerve injury. Gluteal muscle atrophy occurs with prolonged immobility. The muscle is used in myocutaneous flap surgery for pressure ulcer coverage. |
