Explanation:
Detailed explanation-1: -The accessory nerve is tested by evaluating the function of the trapezius and sternocleidomastoid muscles. The trapezius muscle is tested by asking the patient to shrug their shoulders with and without resistance.
Detailed explanation-2: -The spinal accessory nerve is a purely motor entity. It innervates both the trapezius and the sternocleidomastoid muscles.
Detailed explanation-3: -Examination of the accessory nerve involves assessing two muscles: the trapezius and sternocleidomastoid. When assessing the trapezius, ask the patient to shrug their shoulders, then apply resistance. Accessory nerve weakness will present with weak or no resistance to your downward force.
