THE MALE GEXITAL ORGANS 249 am The organ as a whole is nearly cm. long but is largely covered and compressed dorsally by the vesicular and prostate glands (Fig. 100). Its thin ventral wall adheres closely to the expanded terminal portions of the deferent ducts. (c) The somewhat dilated final portions (ampullae) of the deferent ducts lie between the seminal vesicle and the dorsal wall of the bladder. They terminate in the ventral wall of the seminal vesicle, where their point of entrance is marked by a pair of internal papillae. (d) The vesicular gland and the prostate gland lie in the dorsal wall of the more posterior part of the seminal vesicle, the former anterior to the latter, each enveloped in a connective tissue capsule. Macroscopically they are very similar and are associated in a single mass but histologically they are different and are separated by a thin connective tissue septum. In the fresh con- dition, the larger vesicular gland tends to be dull grey while the prostate is cream- coloured. The vesicular gland has a pair of ventral ducts, one of them shown in Fig. 100 which enter the urethra at either side of the seminal coUiculus (vide infra) and the prostate has four to six minute ducts at either side opening just behind them. The paraprostatic glands are minute finger-like pro- jections of the urethral lining imbedded in the outer part of its wall at either side of the base of the seminal vesicle. Their number is variable. Fig. 100. Diagram of sagittal sec- tion of urethra with accessory sex glands and their ducts, from a seven- months old rabbit.
