Absence of Musculocutaneous Nerve Associated with Variations of Distribution Patterns of the Median Nerve

Variations in the brachial plexus and the distribution patterns of its branches are not uncommon. A communicating branch, which is the most frequent variation, often arises from musculocutaneous nerve to median nerve. However, the branches arising from lateral cord of the brachial plexus and median...
