“…Our findings were very much similar to that of Loukas et al, 4 who observed a case of an accessory brachialis muscle that originated from the medial side of the mid shaft of the humerus along with the medial intermuscular septum. It crossed both the brachial artery and the median nerve during its course.…”

“…(8,10) Loukas et al reported a case of bilateral accessory digastric muscles, which originated from the digastric fossa of their respective sidesthe left one was inserted into the midline raphe of the mylohyoid muscle, while the right one immediately bifurcated into two heads. (3) The lateral head rejoined the main belly of the digastric muscle, while the medial head inserted into the midline raphe of the mylohyoid muscle. (3) In the present study, however, the accessory muscle was bilaterally symmetrical.…”

C a s e R e p o r t e131 CA S E R EPO RTDuring routine dissection of the submental region of a 65-yearold female cadaver, we observed an accessory muscle that was bilateral and medial to the anterior bellies of the digastric muscle.Both sides of the accessory muscle were proximally attached to the digastric fossa of the mandible, medial to the anterior bellies of the digastric muscle. The muscle fibres were directed backward, downward and medially, with an intermediate attachment to the body of hyoid bone on either side of the midline at its upper border. The fibres then ran downward and laterally to attach to the medial margin of the lower end of the anterior belly of the digastric muscle and its intermediate tendon (Fig. 1a). This distal part of the muscle was fleshy superficially, while a tendon was observed on its deeper aspect.The accessory bundles were organised superficial to the mylohyoid muscle and deep to the platysma. This supernumerary muscle was innervated by the mylohyoid nerve of the respective sides, from its deeper surface (Fig. 1b). Arterial supply to the muscle was derived from the finer branches of the archana71gupta@yahoo.co.in ABSTRACT During routine dissection of the submental region of a 65-year-old female cadaver, a bilateral supernumerary muscle, medial to the anterior bellies of the digastric muscle, was observed. The accessory muscle bundle was attached proximally to the digastric fossa of the mandible, with an intermediate attachment to the body of hyoid bone and a distal attachment to the medial margin of the lower end of the anterior belly of the digastric muscle and its intermediate tendon on the respective side. These bilaterally symmetrical accessory muscles of the submental region may be erroneously identified as an infarcted submental lymph node or a pseudomass on radiological examinations.

“…George & Nayak (2008), found a case of an acBr that merged with the superficial flexors of the forearm and partly inserted to the olecranon process. Loukas M et al (2006), published a case of an acBr that took origin from mid shaft of humerus and the medial intermuscular septum.…”
