Glandular epithelium of vesicular gland is
Glandular epithelium of vesicular gland is
Show Hint
Most accessory sex glands in domestic male animals (such as the prostate, vesicular glands, and bulbourethral glands) are lined by simple columnar or pseudostratified columnar epithelium, reflecting their active secretory nature.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
The vesicular gland (seminal vesicle) is a paired, lobulated accessory sex gland present in most domestic male mammals (except carnivores like dogs and cats).
Its secretion contributes significantly to the volume and nutrient content of semen.
Step 2: Detailed Explanation:
The microscopic structure of the vesicular gland consists of highly folded mucosal projections lined by a secretory epithelium.
In domestic species, particularly in the bull (ox), the secretory or glandular epithelium is classically described as pseudostratified columnar epithelium.
This epithelium is composed of two primary cell types:
1. Tall columnar secretory cells that reach the luminal surface and exhibit secretory granules containing proteins, fructose, and prostaglandins.
2. Short, basal cells that rest on the basement membrane but do not reach the lumen, acting as progenitor cells.
This arrangement gives the false appearance of stratification (hence "pseudostratified").
Step 3: Final Answer:
Therefore, the correct anatomical classification for this glandular epithelium is pseudostratified columnar type, which is option (A).
