1

Perineum

  • Diamond shaped area
  • Between Medial thighs
  • Anterior to sacrum and coccyx
  • Line divides into:
    • anterior- urogenital triangle
    • Posterior-anal triangle

2

Urogenital Triangle

  • Homologous structure between female and males
    • develop from embryonic primordia
  • Females:
    • Bilateral Primordia 
      • except midline cleft
  • Males:
    • bilateral primordia fused into midline structures

3

Female External Genitals (Vulva)

  • Labia Majora
  • Labia Minor
    • Vestibule of Vagina
  • Clitoris 

4

Labia Majora

  • homologue to scrotum
  • 2 prominent longitudinal folds

5

Labia Minor

  • homologue to ventral surface of penis
  • 2 smaller folds 
  • medial to labia majora

6

Vestibule of Vagina

  • cleft b/w labia minora 
  • urethra, vagina, and ducts of various glands open into

7

Clitoris

  • homologue to penis
  • mobile body (ending in glans) and attached to root
  • composed of 3 cylindrical bodies of erectile tissue

8

Male External genitals

  • Scrotum
  • Testis
  • Epididymis
  • Ductus (Vas) Deferens
  • Penis

9

Scrotum:

  • homologue to labia majora
  • pouch containing:
    • testes
    • epididymides
    • distal part of ductus deferns
  • Scrotal Wall is continuation of superficial abdomiinal fascia
    • contains smooth muscle fibers (dartos muscle)
      • cold temperatures contract

10

Testis

  • homologue to ovary
  • suspended in scrotum  by spermatic cord
  • efferent ductules transport sperm to epididymis

11

Epididymis

  • Cap-like structure
  • superior and posterior to testis
  • stores sperm as they mature

12

Ductus (Vas) Deferens

  • located posterior in spermatic cord
  • Ascends scrotum and passes through
    • superficial inguinal ring
    • abodminal wall

13

Penis

  • homologue to clitoris
  • has
    • mobile body (Shaft)
    •  attached root,
    • prepuce (Fore-skin)
    • glans containing external urethal orifice
  • Composed of 3 cylindrical bodies (Corpora) of erectile tissue
    • paired corpora cavernosa 
      • dorsum of penis
    • single corpus spongiosum
      • contain spony urethra
      • expands distally to form conical glans

14

Deep Perineal Pouch

  • Superior to perineal membrane & superficial perineal pouch
  • adjacent to pelvic diaphragm

15

Male deep perineal pouch contains

  • intermediate (membranous) urethra
  • External urethral sphincter
  • Bulbourethral glands

16

Bulbourethreal glands

homologue to greater vestibular glands

17

Female Deep Perineal Pouch contains

  • urethra
  • external urethral sphincter
  • vagina

18

Blood Supply of Urogenital Triangle

  • Internal pudental artery branches (branch of internal iliac)
    • superficial and deep perineal pouches
    • external genitals
  • Penile Bulb Artery (Vestibular Bulb)
    • bulb
    • corpus spongiosum
  • Deep Artery of Penis/Clitoris
    • corpus cavernosum
  • Dorsal artery of penis/clitoris
    • shaft 
    • glans
