Quick Facts
Origin: From a common supraclavicular nerve trunk formed by the anterior rami of third and fourth cervical nerves (C3-4).
Course: Pierces the deep cervical fascia just above the clavicle and runs inferiorly over the pectoralis major and deltoid muscles.
Branches: None.
Supply: Cutaneous innervation to the skin above pectoralis major and deltoid muscles, as far below as the second rib.
Origin
The intermediate 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 nerves originating from the trunk include the medial and lateral supraclavicular nerves.
Course
The intermediate supraclavicular nerves pierce the deep cervical fascia just above the clavicle. They cross the clavicle to descend over the pectoralis major and deltoid muscles, as far below as the second rib.
Branches
There are no named branches.
Supplied Structures
The intermediate supraclavicular nerves provide cutaneous sensory innervation to the skin above pectoralis major and deltoid muscles, as far below as the second rib.
