Abstract

The lymphatic system of the corpus paracloacalis vascularis and the second fold of the cloaca in the male domestic fowl was investigated by means of the Latex-cast specimens. The lymphatic system of the corpus paracloacalis vascularis (CV) was a complex pear-shaped lymphatic spongy body with a stalk. The lymphatics of the second fold of both sides were connected and formed an arch-shaped, spongy body. The body was divided into 4 parts : the connecting part ; the phallus part ; the round fold part ; and the lymph fold part. The spongy body of the CV was closely connected to that of the second fold ; it was suggested that both bodies, as a system, play a role in the erection of the copulatory organ. The writers recommend the term "Corpus paraclocalis vascularis-Second fold lymphatic system" for these lymphatic structures.
