Branches of Median Nerve 3D

  • Branches of Median Nerve                                                                                                                         

  • Anterior Interosseous Nerve  

    • * Median nerve gives rise to the anterior interosseous nerve in the cubital fossa.
    • * Descends on the interosseous membrane between the flexor digitorum profundus and the flexor pollicis longus.
    • * Passes behind the pronator quadratus, supplying these three muscles, and then ends in sensory “twigs” to the wrist joint.                                            

  • Muscular Branch:

    • * Median nerve enters the palm of the hand through the carpal tunnel deep to the flexor retinaculum and gives off a muscular branch (recurrent branch) to the thenar muscles.                                                                                                                                                                                     

  • Palmar Digital Branches of Median Nerve:

    • * They are five in number and arise in the palm. The medial two branches are common palmar digital nerves. Each divides near a digital cleft to form two proper palmar digital nerves. The lateral three branches are Proper palmar digital nerves.
    • * Supply the palmar aspect and dorsal aspect of distal phalanges of lateral 3½ digits.
