Question

Describe the function of seminal vesicle

Answer 1

Hint: The seminal vesicles (also known as the vesicular or seminal glands) is a pair of glands found in the male pelvis. The seminal vesicles are located in the pelvis superior to the rectum, inferior to the fundus of the bladder and posterior to the prostate.

Complete answer:
- They are also called seminal glands. The semen is secretion of the constituent produced by the males.

- Almost 70-75% of the semen is mainly consists of secretions of the seminal vesicles which mainly includes proteins, enzymes, fructose, mucus, vitamin C, Flavin, phosphorylcholine, and prostaglandins all important biomolecules.

- Their excretory ducts open into the vas deferens. The entire structure and function are mainly controlled by androgens which plays an important part in seminal vesicles.

- The function of the seminal vesicle is to store sperms and to secrete seminal fluid that makes the sperm active. Prostate glands always help in the secretion of nourishment of sperms.

Note:
- The seminal vesicles most important anatomical relation is with the vas deferens, which combine with the duct of the seminal vesicle helps to form the ejaculatory duct, which subsequently drains into the prostatic urethra.
- Inside the gland the structure is found as a honeycombed, lobulated structure with a mucosa lined by pseudostratified columnar epithelium.
- The columnar cells are highly influenced by growing levels of testosterone, resulting in getting taller and are responsible for the ostensible production of seminal secretions.
- Arteries that lead to the seminal gland are derived from the inferior vesical to the internal pudendal and also middle rectal arteries, all of which stem from the internal iliac artery as a main part.
