Question 1

Explain the functions of the Efferent ductules by referring to the histological adaptations to enable it to perform its function.

Answer 1

1. Facilitates the movement of spermatozoa from the seminiferous tubules to the epididymis through:

A- Creation of a flow of fluid from tubuli semineferi to the ductuli efferentes by absorption of fluid by the non-ciliated columnar cells

B- Ciliary activity of the ciliated cuboidal cells

2. Contraction of the fibro-muscular layer of the wall of these tubules creates peristaltic movements from the tubuli seminiferi to the ductuli efferentes
