BALLESTEROS, Luis Ernesto; QUINTERO, Iván Darío  and  FORERO, Pedro Luis. Multiple Muscle and Neurovascular Variations in the Upper Limbs: Case Report. Int. J. Morphol. [online]. 2012, vol.30, n.4, pp.1577-1584. ISSN 0717-9502.

It is presented a rare case of multiple variations in the upper limbs of a 45 years old male cadaver specimen, ownership of the morphology laboratory of the Universidad Industrial de Santander (Bucaramanga, Colombia). Muscle variations were observed (presence of both additional heads of the biceps brachii and the flexor pollicis longus, agenesis of right palmaris longus), nervous variations (anastomosis between median and musculocutaneous nerve and between ulnar and median at superficial palmar level). Additionally it presented the radial artery origin from upper left segment of the brachial artery. These various morphological expressions determine relevant clinical implications and should be taken into account in the various surgical approaches to the upper limbs.

Keywords : Anatomical variation; Biceps brachii muscle; Flexor pollicis longus muscle; Palmaris longus muscle; Median nerve; Musculocutaneous nerve; Ulnar nerve; Radial artery.
