• Source: Lower subscapular nerve

The lower subscapular nerve, also known as the inferior subscapular nerve, is the third branch of the posterior cord of the brachial plexus. It innervates the inferior portion of the subscapularis muscle and the teres major muscle.




Structure


The lower subscapular nerve contains axons from the ventral rami of the C5 and C6 cervical spinal nerves. It is the third branch of the posterior cord of the brachial plexus. It gives branches to 2 muscles:

subscapularis muscle. It usually gives 4 branches to innervate the subscapularis, and can give up to 8 branches.
teres major muscle.




Function


The lower subscapular nerve innervates the subscapularis muscle and the teres major muscle. These muscles medially rotate and adduct the humerus.
