The skin of the infraclavicular region is primarily innervated by what nerves?

The skin of the infraclavicular region is primarily innervated by branches from the cervical plexus, specifically the supraclavicular nerves. These nerves arise from the cervical plexus (roots C3 and C4) and provide sensory innervation to the upper chest and shoulder area, which includes the infraclavicular region.

The suprascapular nerves are important as they contribute to the sensory innervation of the area. This is pivotal for understanding the anatomical relationships and the functional roles of the nerves in supplying sensory feedback from the skin in the infraclavicular area.

This understanding of peripheral nerve distribution is crucial in anatomy, especially in the context of surgical procedures or diagnostic assessments in that region, making it important for students to accurately grasp the anatomy and associated innervation patterns.
