Location of Erb's Point on the neck

The Nerve Point of Neck is situated approximately halfway between the mastoid process and the angle of the mandible, on the posterior border of the sternocleidomastoid. It is the point where the four roots of the brachial plexus (C5, C6, C7, C8, and T1) emerge from behind the muscle.

Clinical Significance

The Nerve Point of Neck is of significant clinical importance. It is the site of injection for a Brachial plexus block, a type of regional anesthesia used in surgeries of the upper limb. It is also the point where the Spinal accessory nerve can be palpated, which is useful in diagnosing conditions such as Spinal accessory nerve palsy.
