Solo en la clase mamiferos se describe este plano muscular, considerablemente desarrollado en algunas especies como los roedores, que se extiende ampliamente sobre el torax, el abdomen y el dorso; capa muscular de ubicacion subcutanea, conocido como Panniculus carnosus (Langworthy, 1924).

Este patron de inervacion, proveniente de ramos primarios ventrales de nervios raquideos, tal como ocurre con el Panniculus carnosus de mamiferos inferiores, da soporte a la teoria de que estos fasciculos detectados ocasionalmente en humanos corresponden a remanentes vestigiales en la fosa axilar de aquel extenso plano muscular (Langworthy; Besana-Ciani & Greenall).
