The shoulder and the shoulder joint is innervated by the axillary nerve and the suprascapular nerve
Minor contributions from the long thoracic nerve and capsular filaments from the infraspinatus nerve are not clinically significant
The figure shows the bony structures of the shoulder from an anterior and a posterior view. The axillary nerve innervates the anterior side (purple). The suprascapular nerve innervates the posterior side (“bone” color). The blue color is innervated by the radial nerve.
