B) Finger flexion
C) Diaphragm
D) Trunk muscle
Ans: C
Feedback:
The functional levels of cervical injury are related to C5, C6, C7, or C8 innervation. All motor and sensory function is absent below the level of cord transection. At the C5 level, deltoid and biceps function is spared, allowing full head, neck, and diaphragm control with good shoulder strength and full elbow flexion. At the C8 level, finger flexion is added. Thoracic cord injuries (T1 to T12) allow full upper extremity control with limited to full control of intercostal and trunk muscles and balance. Sacral (S1 to S5) innervation allows for full leg, foot, and ankle control and innervation of perineal musculature for bowel, bladder, and sexual function.
