Rabbits -- Anatomy. 136 ANATOMY OF THE RABBIT the sac being completed medially by the mediastinal pleura. The two last mentioned are broadly connected with the pulmonary pleura through the pulmonary ligament. The peritoneal cavity, the largest of the serous spaces, com- prises in a mammal a general portion, the abdominal cavity, and its posterior extension into the pelvisâin the male also into the sac of the testis or scrotum. The general relation of the cavity to the abdominal organs is indicated diagrammatically in Fig. 20. Its lining membrane, the peritoneum, is divisible into two principal por- tions, the parietal peritoneum, lining the abdominal wall, and the visceral peritoneum, investing the visceral organs. Of the latter, the kidneys encroach only to a minor extent on the serous lining, so that they are covered by peritoneum only on their ventral surfaces. The digestive tube, on the other hand, is removed to such an extent from the abdominal wall that the peritoneum forms a complete serous coat, and is connected with the parietal peritoneum of the wall through a thin transparent membrane, the mesentery. The latter consists relation of the testis to its invest- of two platcs of peritoncum, cnclosins: ments: ai, inguinal ring; ce, caput . epididymidis; cr, cremaster muscle; bctWCCn them a thin layer of COU- dd, ductus deferens; g, guber- , . i i ⢠â¢â¢ naculum; mes, mesorchium; ptv and nCCtlVC tlSSUC, the lamma meseuteni vtv, parietal and visceral layers of ⢠r i ⢠⢠r the tunica vaginalis propria; pv, propria, lor the transmission oi ncrvcs, cavity of the vaginal process; s, , , , , . , â , , integument of the scrotum; sv. blOOO-VCSSelS, and lymph CaualS. spermatic vessels; t, testis. a ⢠j* ^ j ⢠i- i j.
