Accessory nerve
Overview
The spinal root of accessory nerve (or part) is firm in texture, and its fibers arise from the motor cells in the lateral part of the anterior column of the gray substance of the medulla spinalis as low as the fifth cervical nerve., A spinal accessory nerve injury can be caused by trauma or damage during surgery, that a more distal injury to the spinal accessory nerve may spare function to the sternocleidomastoid and interrupt function to the trapezius.
