[Contribution to the study of the cervical lymphatic system of the young and adult white rats (Rattus norvegicus). II (author's transl)].
This report is based upon microdissections of 30 young white rats and 21 adults, of both sexes, in which it was studied the morphology of cervical lymphatic system performed by injection of submandibular and deep cervical nodes with latex-neoprene colored. It was verified that: there are no differences between the lymph nodes of young and adult rats: the presence of a submandibular chain with variable number of lymph nodes; this chain give efferent lymphatic branches to the deep cervical lymph nodes; the presence of 2 groups of deep cervical lymph nodes, one caudal and other cranial; those lymph nodes give efferent branches which are going to form the deep jugular trunk, the join to the jugulo-subclavian angle; the jugular trunk may go to joing to branches coming from the thoracic limb, from the thorax cavity and branches which go along the external jugular vein and omocervical vein.
