Axillary Nerve Anatomy

Axillary Nerve | Axillary Nerve Course, Branches, Muscle Supply, Test & Palsy


Axillary Nerve is also called Circumflex Nerve. Axillary Nerve run around surgical neck of humerus.


    ROOT VALUE OF AXILLARY NERVE :-


    => Root value of Axillary Nerve Is C5, C6 segment of spinal cord.


    COURSE OF AXILLARY NERVE :-

    => Axillary Nerve is terminal branch of posterior cord of the brachial plexus.

    => Axillary Nerve pass backword through quadringular space 

    => Axillary Nerve is divided in two division anterior and posterior at behind surgical neck of humerus 

    BRANCHES OF AXILLARY NERVE :- 


    => Muscular branches : supply to the Deltoid and Teres minor

    => Cutaneous branches : supply to the of skin over inferior portion of the shoulder 

    => Articular branch : supply to Shoulder joint


    AXILLARY NERVE SUPPLY :

    Motor Supply

    axillary nerve
    Axillary Nerve

    => Motor supply of Axillary Nerve is only two muscle Deltoid and Teres minor 

    => Pseudoganglion present between supply suuply of Teres Minor muscle.

    Sensory

    => Sensory supply by Upper lateral cutaneous nerve to skin over inferior portion of the shoulder 

    AXILLARY NERVE INJURY / AXILLARY NERVE PALSY :-


    => Injury to the Axillary Nerve loss motor function & paralysis of Deltoid and Teres minor muscle. also loss of sensory part (skin over inferior portion of shoulder)

    => Mainly Abduction are loss on affected side due to parlysis of the deltoid muscle.
