Difference between anterior branch and posterior branch of axillary nerve Anterior branch of axillary nerve posterior branch of axillary nerve ·          The  anterior branch  (upper branch) winds around the surgical neck of the humerus beneath the deltoid muscle, with the posterior humeral circumflex vessels. It continues as far as the anterior border of the deltoid to provide motor innervation. The anterior branch also gives off a few small cutaneous branches, which pierce the muscle and supply in the overlaying skin. ·          .   The  posterior branch  (lower branch) supplies the teres minor and the posterior part of the deltoid The posterior branch pierces the deep fascia and continues as the superior (or upper) lateral cutaneous nerve of arm, which sweeps around the post...

It can range from a barely observable, undeveloped digit to a fully developed, functioning digit. When syndactyly and polydactyly are present simultaneously, it is called Polysyndactyly.. Syndactyly is webbing or fusing between the digits (fingers or toes). The digits can be partially fused or fused along their entire length. The severity can range from simple fusion with digits connected only by skin to more complicated fusion with shared nerves, blood vessels, bones, and/or nails. Syndactyly most commonly occurs between the middle two fingers The occurrence of polydactyly varies from 1 in 3,300 to 1 in 630 for American Caucasians and from 1 in 300 to 1 in 100 for American Blacks One in 3,000 children in North America is born with syndactyly.
