Seminal Vesicles

The Seminal Vesicle (vesiculae seminalis) is a paired glandular organ located laterally to the Ductus deferens, superior to the Prostate Gland.

The wall of the seminal vesicle is formed by three tunics (layers):

1) a mucosa, lined with a simple columnar epithelium resting on a thin basement membrane. The lamina propria of the mucous membrane contains numerous elastic fibers. Distributed within the mucosa are the terminal portions of alveolar glands, which consist of mucous exocrinocytes (exocrinocytus mucosus);

2) a muscularis, consisting of two layers of smooth Muscle Cells: an inner circular layer and an outer longitudinal layer;

3) an adventitia, formed by dense Fibrous Connective Tissue rich in elastic fibers.
