Histology of Vas Deferens \ Ductus Deferens
Вставка
- Опубліковано 28 жов 2020
- The Vas Deference or Ductus deferens is a thin, fibromuscular tube initiating from the epididymis and converting into the ejaculatory duct in the male reproductive system. Being 30-45cm long and less than 5mm in diameter, it serves in transporting sperm cells from each of the testis to the common ejaculatory duct.
he vas deferens is made up of 3 layers:
Outer layer
Middle muscular layer
Internal mucous layer
The middle layer is made up of smooth muscle fibers from the outside and circular muscles from the inside, making the middle layer thicker than the diameter of the lumen. The proximal part of the duct further differentiates these two layers into outer and inner layers made up of longitudinal smooth muscles and another middle layer consisting of the circular muscle fibers. Reaching towards the inguinal canal the innermost layer of longitudinal muscle fibers get eliminated. This 1.5m thick muscular layer is lined with the mucous layer, made up of pseudostratified columnar epithelial cells, having anterior stereocilia that help the sperm cells to move smoothly throughout the tube; providing a protective covering to the lumen. The diameter of the lumen is 2.5mm.
