44

Epididymis: Position

Posterolateral surface of testis

45

Epididymis: Parts

Head →receives spermatozoa via the efferent ducts
The Body
The Tail → absorbing fluid to make the sperm more concentrated

46

Epididymis: Functions

Storage of sperm

47

Ductus Deferens: Structure

48

Ductus Deferens: Origin

Epididymis

49

Ductus Deferens: How does this enter the abdomen

Deep ring to superficial inguinal ring then into abdomen

50

Ductus Deferens: This joins with the ducts of which glands to form the ejaculatory ducts

Seminal vesicles

51

58

Prostate Gland:Function

is to secrete a slightly alkaline fluid, milky or white in appearance, that usually constitutes 50–75% of the volume of the semen along with spermatozoa and seminal vesicle fluid.

59

Seminal vesicles: Structure

Series of glands that drain into a central duct,

60

Seminal vesicles:Function

Secrete fluid that becomes semen

61

Seminal vesicles:Ducts of seminal vesicles join which other ducts to form the ejaculatory ducts

Vas deferens

62

Seminal vesicles:Sympathetic contractions leads to

Mixing of sperm and fluid

63

Bulbourethral glands: Structure

compound tubulo-alveolar glands, each approximately the size of a pea in humans.

64

Bulbourethral glands: Function

During sexual arousal each gland produces a clear, salty, viscous secretion known as pre-ejaculate. This fluid helps to lubricate the urethra for spermatozoa to pass through, neutralizing traces of acidic urine in the urethra,[4] and helps flush out any residual urine or foreign matter.

65

Bulbourethral glands: Where are they found

Posterior and lateral to the membranous portion of the urethra at the base of the penis, between the two layers of the fascia of the urogenital diaphragm, in the deep perineal pouch.
