RESUMEN

Introduction: In most of cases, the emergency of the nervous roots of the brachial plexus in the posterior cervical triangle occur between the anterior and middle scalene muscles. However, anatomic variations in the brachial plexus are not rare. Methods: In the laboratory of Human Anatomy of the "Faculdade de Ciências Médicas de Minas Gerais" 106 cadavers were dissected. There were dissected the cervical region of all of the cadavers bilaterally. Results: In routinely dissection in the laboratory of human anatomy of the "Faculdade de Ciências Médicas de Minas Gerais" we've found in the left cervical region of a male cadaver the ventral branch of the seventh cervical nerve (C7) perforating the substance of the middle scalene muscle. Conclusion: Professionals that work with this region on the practice must pay attention to this and other variations in the constitution of the brachial plexus in the clinic and surgical procedures to avoid complications.(AU)

RESUMEN

The rectus abdominal muscle is part of the anterior abdominal wall, having three to six bellies. In only oneof the 106 dissections already made in the “Faculdade de Ciências Médicas de Minas Gerais” AnatomyLaboratory was found a male cadaver who did not have inferior venter of this muscle bilaterally. Instead, at theleft side, was found a tendon that measured 5.5 cm laterally and 12 cm medially, and at the right side, therewas the same variation with a 15.5 cm length tendon, rising in the upper branch of the pubis and crest pubis.Despite being a rare variation, individuals who have showed it have increased potential for physiological andsurgical complications, in case they need interventions using inferior rectus abdominis muscle venter’s snips.

RESUMEN

The Abductor Pollicis Longus (APL) is known to have a big variety in its number of insertion tendons.Because of that, studies about variations in its origin are not frequently achieved like studies about its insertionforms. This study describes an anatomic variation of the Abductor Pollicis Longus, with an anomalous venteroriginated of the inferior portion of the lateral border of the radio. Surgical and clinical implications are inrelation principally with the big number of tendons of insertion of the APL, but there are related cases inthe literature in that additional venter of this muscle also can be involved in the physiopathology of clinicalsyndromes, like the tenosynovitis of de Quervain
