From Wikipedia, the free encyclopedia
The lower subscapular nerve , also known as the inferior subscapular nerve ,
[1] 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 .
[2]
[3] It is the third branch of the
posterior cord of the
