-Contributes the majority of the total seminal plasma volume (~70%)
-Is a diverticulum of the ductus deferens; its cavities give it a honeycomb-like appearance
-Connective tissue folds comprise an elastic lamina propria and secretory pseudostratified epithelia
-Within the cytoplasm of the epithelia cells, lipid droplets give the glandular tissue a characteristic foamy appearance.
-Indicate the thick smooth muscle that surrounds the mucosa; during emission, the smooth muscle contracts to drain the seminal vesicle fluid into the ejaculatory duct.
