    Clinical implications caused by the agenesis of the rectus abdominal muscle’s (MRA) inferior venter.
    (2013) Ribeiro, Débora Machado Cunha; Siqueira, Sávio Lana; Soares, Gabriela Romaniello; Gama, Henrique Valladão Pires
    The rectus abdominal muscle is part of the anterior abdominal wall, having three to six bellies. In only one of the 106 dissections already made in the “Faculdade de Ciências Médicas de Minas Gerais” Anatomy Laboratory was found a male cadaver who did not have inferior venter of this muscle bilaterally. Instead, at the left side, was found a tendon that measured 5.5 cm laterally and 12 cm medially, and at the right side, there was 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 and surgical complications, in case they need interventions using inferior rectus abdominis muscle venter’s snips.

    Third head of the biceps brachii muscle and a communication between the musculocutaneous and median nerves : a case report.
    (2019) Dussin, Caroline; Oliveira, Lucas Moysés Carvalho de; Siqueira, Sávio Lana
    Many authors have reported and classified several anatomical variations between the musculocutaneous (Mc) and median (Me) nerves, regarding their origin, number, and proximity with the coracobrachialis muscle. There also are, in the scientific community, records classifying the origin of supernumerary heads of the biceps brachii muscle. However, the occurrence of both aforementioned variations in the same arm is very uncommon. During a routine dissection of the right upper limb of a male cadaver, a third head of the biceps brachii was found originating from the fibers of the brachialis muscle, as well as a communicating branch between the Mc and the Me nerves, in the same limb. The objective of the present case report is to describe these multiple variations found, relating them and discussing their relevant clinical implications.
