Origin

The lateral supraclavicular nerves are one of the three groups of nerves that arise from a common supraclavicular nerve trunk. It receives its sensory neurons from the anterior rami of third and fourth cervical nerves. The other nerve groups originating from the trunk include the medial and intermediate supraclavicular nerves.

Course

The lateral supraclavicular nerves pierce the deep cervical fascia just above the clavicle. These then descend superficially across the trapezius muscle and the acromion process.

Branches

There are no named branches.

Supplied Structures

The lateral supraclavicular nerves provide cutaneous innervation to the upper and posterior shoulder regions.
