The Lymphatic system of the anterior limb in Dasypus novemcinctus novemcinctus Linne, 1758 (Mammalia: Edentata)

Abstract

The aim of this work is to realize a revision of the anterior limb lymphatic draining of the Dasypus novemcinctus novemcinctus. 15 armadillos clinically healthy, male and female were utilized; they had been captured in the Argentine Northeast and were injected by the Gerota's Paste  modified method. The injection was realized at the fourth toe level on the medial side as well as on the lateral one; on the interphalangeal area, and on the left one over the manmary gland of both sides. The classical dissections were carried out with a surgery microscope, of Varimex type. The microphotographs were realized with a Zeiss microscope. The exhaustive analysis of the anterior limb area showed the following conclusions: the lymphatic circulation was observed from the distal extremity of the injected area to the axillar lymphocenter from where emitted 2 or 3 efferent lymphatic vessels; they were directed to the superficial inguinofemoral lymphonodule. The limphonodule situated by the scapula caudal border received one efferent lymphatic vessel which came from the superficial cervical lymphonodule and another efferent
lymphatic vessel which led to the axillar lymphocenter.
