    Study Notes

    Brachial Plexus

    • The brachial plexus is formed by the ventral primary rami of C5, C6, C7, C8, and T1.
    • The branches from the roots supply muscles that join the trunk to the pectoral girdle.

    Branches from Roots

    • Dorsal scapular nerve (C5)
    • Long thoracic nerve (C5-C7)
    • The long thoracic nerve is vulnerable to injury during radical mastectomy or traumatic injury due to its superficial location on the serratus anterior muscle.

    Trunks

    • The three trunks are formed by the union of the posterior divisions of all three trunks.

    Divisions and Branches

    • The upper subscapular nerve (C5, C6) supplies the subscapularis.
    • The middle subscapular (thoracodorsal) nerve (C6, C7, C8) supplies the latissimus dorsi.
    • The lower subscapular nerve (C6, C7) supplies the subscapularis and teres major.
    • The axillary nerve is a terminal branch.
    • The radial nerve is a terminal branch.
    • The musculocutaneous nerve (C5-C7) is another branch.
