URETHRA

  • It is a thin walled muscular tube that drains the urine from the urinary bladder and conveys it out of the body.

Male urethra:

-It is total length about 8 inches (20cm).

Histology:

(Same as the bladder)

Female urethra:

  • It is about 1.5 inch (4 cm) long.
  • It opens to the outside at the external urethral orifice which lies anterior to the vaginal opening (in the vestibule).
  • It is embedded into the anterior wall of the vagina.

Vascular supply:

Arteries:

  • intramural part: inferior vesical artery (from the internal iliac artery)
  • pelvic part: uterine and vaginal arteries (from the internal iliac artery)
  • perineal part: internal pudendal artery (from the internal iliac artery)

Veins:

  • intramural part: vesical venous plexus (via the vesical veins to the internal iliac vein)
  • pelvic part: vaginal venous plexus (via the vaginal veins to the internal iliac vein)
  • perineal part: internal pudendal veins (to the internal iliac vein)

Lymphatic drainage: paravesical nodes (to the common, internal and external iliac nodes)

Sympathetic and parasympathetic, visceral sensory and (somatic) motor nerve fibers: vesical plexus
