Key Points:
• Innervates the subscapularis and teres major muscles.
• Originates from roots C5, C6, C7.
• Subscapularis and teres major are tested as a group.
EXAMINATION

Innervation
• Roots: C5, C6, C7.
• Nerve: Lower subscapular nerve.
• Muscles Innervated: Teres major, subscapularis.
• Innervation Route:
• C5, C6, C7 → posterior cord → lower subscapular nerve → teres major.
• C5, C6, C7 → posterior cord → lower subscapular nerve → subscapularis.
