15.32 Ampulla of the vas deferens

Version française

Transverse section of the ampulla of the vas deferens from a dog.

This ampulla is a dilatation of the vas deferens as it approaches the seminal vesicle and the prostate (see Figure 15.1).

The large lumen of this duct is delimited by a thick mucosa showing numerous branching and interconnected folds (arrows). These folds are lined with a simple columnar epithelium. This mucosa is similar to that of the seminal vesicle shown below (see figures 33 to 37).

The wall of the duct shows a thick muscular coat in which the smooth muscle fibres, which run circularly or longitudinally, form two distinct layers, the inner circular (*) and the outer longitudinal (+) layers.
