Resumo
In the present work the authors studied the morphology of the cervical lymphatic system using 26 new-born white rats of both sexes. The studies were performed by injecting China-ink under the skin of the angle of mouth and dorsal region of the auricle in order to visualize and then to proceed the dissection of lymph vessels and nodes under stereoscopic microscope. Morphological descriptions of superficial and deep lymph vessels and lymph nodes were made, recording: a dense capillary network of the superficial system that joins to larger branches going to the submaxillary lymph nodes, generally the only ones on each side; those lymph nodes send efferent branches to deep cervical lymph nodes generally also the only ones on each side; those lymph nodes give efferent branches which form the jugular lymphatic sac that joins the jugulo-subclavian junction; the jugular lymphatic sac may receive branches from the plexus, which accompany the omocervical and external jugular veins and branches coming from the thoracic limb, as well as may join the branches coming from the thorax and the branches in most of the cases form plexus branches and seldom appear by themselves.
