    • anus and 
    • external anal sphincter 
    • anus
    • different from male
    • external urethral orfice
    • vaginal orfice
  18. deep pouch male  contents?
    • deep perineal vessel
    • dorsal ner of and vessel of penis 
    • external urethral spihincter
    • Bulbourethral gland 
    • deep transverse perineal
  19. erectile tissue of the female superficial pouch
    • crus of the clitoris 
    • bulb of the vestible 
    • body of the clitoris 
    • greater vestibular gland or Barthalands gland
  20. what muscles covers the crus of the clitoris
    isocavernosium
  21. male perineum vs. female perineum
  22. what are the boundaries of the superficial pouch ?
    skin to perineal membrane
  23. what are the boundaries of the deep pouch?
    perineal membrane to the diaphragm
  24. erectile male tissue of the superficial pouch
    • Crus of the penis
    • Bulb of the penis
    • Corpus cavernosum
  25. Muscle of the male superficial pouch ?
    • Ischocavernosous
    • Ralphe of bulbospongiousus
    • Bulbospongious
    • superficial transvers perineal 
    • perineal body
    • external anal spinchter 
    • anus
  26. what muscle overlays the bulb of the penis corpus spongiosum ?
    Bulbosponggiosum and ralphe
  27. what muscle overlaps the crus of the penis
    the ishiocavernosum
  28. what are the boundaries of the deep pouch ?
    perineal membrane to the pelvic diapragm
  29. difference between internal and external anal sphincters?
    • internal sphincter is visceral motor while external is somatic motor
    • internal is portal venous  and iferior mesenteric artery
    • external is caval venous and internal illiac artery
  30. mechanism of defecation ?
    • 4 main steps
    • strecth receptors send signal to the spinal cord 
    • parasymp contraction of rectum 
    • para sym relaxes internal anal sphinc
    • voluntary impulses travel through somoatic motor fibers to relax the external anal sphinc

    internal is less painful above the pectinate line and atutomonics
  32. Internal hemrroids?
    • happen above the pectinate line 
    • are less painful 
    • autonomic nerves
  33. External hemorroids
    • painful 
    • somatic nerves ( you know where it is exactly)
    • below the pectinate line
  34. What are the main places that hemrroids can happen?
