Análisis descriptivo de la miología flexora y extensora del miembro anterior de Polychrus acutirostris (Squamata, polychrotidae)

Abstract

The musculature of the forelimb of Polychrus acutirostris is described. The anatomy of the flexor and extensor muscles was analyzed, with a record of the sites of origin and insertion and main characteristics for each muscle. The main purposes of this work are: to contribute to the identification of the muscular complexes of the forearm and manus; to update the nomenclature of certain complicated muscles; and to present a model of the forelimb musculature of an arboreal lizard, to allow comparisons with the muscular anatomy of lizards with other locomotor habits.
