    Dorsal artery of the penis/clitoris
    Deep artery of the penis/clitoris
    Posterior labial/scrotal artery

  4. The vestibular bulbs/bulb of the corpus spongiosum are firmly attached to the:
    Perineal membrane
    Superior pubic rami
    Ischiopubic rami

  5. What part of the ischioanal (ischiorectal) fossa extends deep to the sacrotuberal ligament?
    Anterior recess
    Genital hiatus
    Posterior recess
    Pudendal canal
  6. The perineum is bounded by all of the following skeletal elements except:
    coccyx
    ischiopubic ramus
    spine of ischium
    symphysis pubis
  7. During childbirth, a bilateral pudendal nerve block may be performed to provide anesthesia to the majority of the perineum and the lower one fourth of the vagina. To do this an anesthetic agent is injected near the pudendal nerve as it passes from the pelvic cavity to the perineum. The physician inserts a finger into the vagina and presses laterally to palpate what landmark?
    Arcus tendineus levator ani
    Coccyx
    Ischial spine
    Lateral fornix
    Obturator foramen
  8. During a vaginal delivery, a surgeon performed median episiotomy in which he cut too far (i.e., through the perineal body into the structure immediately posterior). Which perineal structure did he cut?
    Bulbospongiosis muscle
    External anal sphincter muscle
    Ischiocavernosis muscle
    Sacrospinous ligament
    Sphincter urethrae
  9. A patient complains of a boil located on her labia majora. Lymphatic spread of the infection would most likely enlarge which nodes?
    Lumbar nodes
    Sacral nodes
    External iliac nodes
    Superficial inguinal nodes
    Internal iliac nodes
  10. In order to perform an episiotomy prior to childbirth, the perineum must be anesthetized. By inserting a finger in the vagina and pressing laterally, what palpable bony landmark can be used as the posterior limit of the pudendal canal?
    Coccyx
    Ischial tuberosity
    Ischiopubic ramus
    Obturator groove
    Ischial spine
  11. Which of the following would be most likely to be damaged by a stab wound into the ischiorectal (ischioanal) fossa 2 cm lateral to the anal canal?
    Crus of the Penis
    Perineal Body
    Pudendal Nerve
    Inferior Rectal Artery
    Vestibular Bulb
  12. Which pair of structures does NOT differentiate from comparable embryonic structures in the male and female?
    Bulb of corpus spongeosum and vestibular bulb
    Shaft of penis and labia majora
    Glans of penis and glans of clitoris
    Crus of corpus cavernosum penis and crus of corpus cavernosum clitoris
  13. A structure which takes the form of a hood anterosuperior to the clitoris:
    Frenulum of the clitoris
    Labia majora
    Labia minora
    Prepuce
  14. A structure which is homologous to the male scrotum:
    Labia minora
    Labia majora
    Glans
    Shaft of corpus cavernosum
  15. Which skeletal feature would you consider to be most characteristic of the female pelvis?
    Subpubic angle of 90 degrees or greater
    Marked anterior curvature of the sacrum
    Tendency to vertical orientation of the iliac bones
    Prominent medial projection of the ischial spines
  16. The male pelvis tends to differ from the female pelvis in that the male pelvis often has a:
    larger pelvic inlet
    smaller subpubic angle
    straighter sacral curvature
    larger pelvic outlet
    rounder pelvic inlet
