Lower subscapular nerve
Updates to Article Attributes
The lower subscapular nerve, also known as the inferior subscapular nerve, arises from the posterior cord of the brachial plexus and supplies the subscapularis muscle and contributes fibres to theteres major muscle.
Gross anatomy
Origin
The lower subscapular nerve branches from the posterior cord of the brachial plexus with fibres arising from the fifth and sixth cervical nerves. The lower subscapular nerve branches distal to the origin of the thoracodorsal nerve.
Course
The lower subscapular nerve travels inferiorly from the brachial plexus to supply the lower part of the subscapularis muscle. It donates a branch to the teres major muscle which courses in the angle between the subscapular and circumflex scapular arteries.
Supply
It supplies thesubscapularis muscle and contributes fibres toteres major.
Relations
The lower subscapular nerve is the larger of the subscapular nerves.
