Q

What are the vessels of the penis?

A
  • x2 Dorsal arteries (Accompanies dorsal nerves (from pudendal n.) BELOW DEEP FASCIA OF PENIS
  • x1 Deep dorsal vein
  • x2 Deep arteries (Inside corpora cavernosa)

and superficial dorsal veins of penis

NB equivilents in females but much smaller with shorter courses

Q

Describe the structure of the testis:

A
  • Tough fibrous outer capsule (tunica albuginea)
  • Seminiferous tubules wind into lobules (1-3 per lobule) which opens into rete testis
  • Efferent ductules connect rete to epididymis
  • Epididymis stores sperm (3 degrees cooler, optimal)
  • Epididymis becomes vas deferens

Q

Describe the vas deferens and its anatomical connnections:

A
  • Muscular tube
  • Travels in spermatic cord
  • Joins duct from seminal vesicle to form ejaculatory duct
  • Ejaculatory duct into prostate to join urethra

Q

Describe the course of the vas deferens:

A
  • Enters body cavity lateral to inferior gastric art (from spermatic cord)
  • Crosses over external iliac vessels, passing medially towards prostate
  • Passes over the top of the ureter to join seminal vesicles (and form ejaculatory duct)

Q

What sort of tissue is the prostate and how can it be divided?

A

Prostatic tissue: Alveoli lined with columnar glandular epithelium (Embedded in thick muscular stroma)

Zones:

  • Peripheral (majority of gland)
  • Central (around ejaculatory ducts)
  • Transitional (around urethra and mostly respondible for benign prostate hyperplasia)
  • Anterior (non-glandular)

Q

What are the three main effects of prostatic enlargement?

A
