The nerve<unk>  of the neck, also known as Erb's<unk>  is a site at the upper trunk of the brachial plexus located 2–3 cm above the clavicle. It is named for Wilhelm Heinrich Erb. Taken together, there are six types of nerves that meet at this<unk> . "Erb's<unk> " is also a term used in head and neck surgery to describe the<unk>  on the posterior border of the sternocleidomastoid muscle where the four superficial branches of the cervical plexus—the greater auricular, lesser occipital, transverse cervical, and supraclavicular nerves—emerge from behind the muscle. This<unk>  is located approximately at the junction of the upper and middle thirds of this muscle. From here, the accessory nerve courses through the posterior triangle of the neck to enter the anterior border of the trapezius muscle at a<unk>  located approximately at the junction of the middle and lower thirds of the anterior border of this muscle. The spinal accessory nerve can often be found 1 cm above Erb's<unk> .
