1. Lesser occipital nerve (C2) - a slender branch that hooks around CN XII and runs up along the posterior border of the SCM to supply the back of the neck up to the superior nuchal line, back of the auricle.

2. Great auricular nerve (C2, 3) - a large trunk passing vertically upwards across the SCM to supply the angle of the mandible, parotid gland, parotid fascia, auricle.

3. Transverse cervical nerve (C2, 3) - a single trunk that emerges from the posterior border of the SCM, quickly breaks up into a number of branches to supply the midline of the neck from the chin to the sternum.

4. Supraclavicular nerve (C3, 4) - emerges from the posterior border of SCM to divide into 3 branches (medial, intermediate, lateral).
