Abstract

VELEZ GARCIA, Juan Fernando; DUQUE PARRA, Jorge Eduardo  and  BARCO RIOS, John. Anatomical Description of White-Footed Tamarin (Saguinus leucopus Günther, 1877) Brachioradialis Muscle, and the Finding of an Accessory Head as an Anatomical Variant. Int. J. Morphol. [online]. 2015, vol.33, n.1, pp.169-172. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022015000100027.

The Saguinus leucopus is a neotropical, endemic, and monotypic Colombian primate; few studies have been reported about its anatomy, specially about its muscles, this being a fundamental element for the active motion of this primate in the trees. The aim of this study was to describe the gross anatomy of the brachioradialis muscle on the white-footed tamarin (Saguinus leucopus). Ten specimens were included in the study, fixed with formalin at 10% and their thoracic limbs dissected, from the superficial to the deep plane, describing the form, origin, insertion, innervation and irrigation of the Brachioradialis muscle. The conclusion we made is that this muscle represents a morphology and in this way it must contribute to the flexor and supinator elbow movements, and would have an accessory head in this species.
