They furnish one or two filaments to the [[sternoclavicular joint]]. ===Intermedial supraclavicular nerve=== The '''intermedial supraclavicular nerve''' ''middle supraclavicular nerves'' (nn. supraclaviculares medii; supraclavicular nerves) cross the [[clavicle]], and supply the skin over the [[pectoralis major]] and [[deltoideus]], communicating with the cutaneous branches of the [[upper intercostal nerves]]. ===Lateral supraclavicular nerve=== <!--Lateral supraclavicular nerve redirects here--> The '''lateral supraclavicular nerve''' or ''posterior supraclavicular nerves''<ref>[http://www.biology-online.org/dictionary/Posterior_supraclavicular_nerve Biology-online]</ref>(nn. supraclaviculares posteriores; supra-acromial nerves) pass obliquely across the outer surface of the [[trapezius]] and the [[acromion]], and supply the skin of the upper and posterior parts of the [[shoulder]]. ==Additional images== <gallery> Image:Gray784.png|Dermatome distribution of the trigeminal nerve Image:Gray811and813.PNG|Cutaneous nerves of right upper extremity.
