CONTENTS Efferent ductules Epididymis Prostate gland

EFFERENT DUCTULES Simple epithelium Thin muscular wall Saw tooth appearance of the lumen due to alternating groups of tall (ciliated) and short (microvilli) lining cells.

EPIDIDYMIS It is a single elongated duct composed of head, body & tail 4-5 m long, yet occupies an area of 5 cm long

1: Epididymis 2: Head of epididymis 3: Lobules of epididymis 4: Body of epididymis 5: Tail of epididymis 6: Duct of epididymis 7:DUCTUS DEFFERENS

FUNCTIONS Principle storage area for sperms Transportation Resorption of fluid Acquire motility and ability to fertilize ovum

DUCTUS EPIDIDYMIS has a larger diameter lumen with a smooth outline and a thicker muscular coat

DUCTUS EPIDIDYMIS Androgen dependent maturation Presents smooth internal as well as external contour Epithelium ---- Principal cells, Basal cells

Function of principal cells Secretory & absorptive capacity for nurture & maturation of spermatozoa Head region ----- active in fluid absorption Tail region ----- Storage compartment

PROSTATE Largest accessory sex gland size & shape Location

ZONES Adult prostatic parenchyma is divided into four anatomically & clinically distinct zones: The peripheral zone The central zone The transitional zone

Corpora amylacea (prostatic concretions) Prostatic epithelial cells (Simple cuboidal) produce: Enzymes especially PAP Fibrinolysins Citric acid Serine protease (PSA)
