Anatomical Study of the Digastric Muscle: Variations in the Anterior Belly Estudio Anatómico del Músculo Digástrico: Variación en el Vientre Anterior
The digastric muscle is formed by two muscle bellies: one anterior and one posterior, joined by an intermediate tendon. It is localized in the anterior cervical region. The anterior belly divides the region between the hyoid bone and the mandible into two: laterally the submandibular triangle, and medially the submental triangle. The anatomical variations described in the literature relate to t...
متن کاملBilateral bipartite origin of the posterior belly of digastric muscle: a clinico-anatomical appraisal
Anomalous digastric muscle may be an incidental finding during routine dissections or autopsies which may be asymptomatic or symptomatic. While performing routine educational dissection of the submandibular region of the neck, we encountered a unique bilateral composition of the digastric muscle. The posterior belly of digastric displayed a bifid origin. Two muscle bellies emanating from the di...
متن کاملA bilateral and symmetrical variation of the anterior belly of the digastric muscle.
We observed a bilateral and symmetrical variation of the anterior belly of the digastric muscle during the dissection of a 35-year-old female cadaver. The accessory muscle bundles were arranged in a cross. These bundles were found superficial to the mylohyoid muscle and deep in the platysma. Such a variation from perfect symmetry has not been previously reported. To avoid misinterpretation of r...
متن کاملAnalysis of histochemically and morphometrically in the anterior belly digastric muscle of osteopetrotic (op/op) mice.
The fibers of the anterior belly digastric muscle of mice, fed a granulated diet for various periods, have been studied histochemically and morphometrically. The diameters of the anterior belly digastric fibers in normal mice fed only a granulated diet were smaller than those in mice fed a solid diet. Differences in the succinate dehydrogenase (SDH) activity of muscle fibers between op/op and n...
متن کاملThe digastric muscle's anterior accessory belly: case report.
Digastric muscle is characterized by presenting occasional variations. The suprahyoid region of an 83 year-old male cadaver was dissected and an anatomic variation of the digastric muscle was observed in its anterior belly. It consisted of an accessory bilateral anterior belly originating in the intermediate tendon and inserted into the mylohyoid raphe. The implications of this variation are di...
