Overview

This course entails multiple choice questions in anatomy of pelvis mainly for gynecologists and obstetricians and urologists as well as medical students. It is arranged according to structures and regions of pelvis anatomy. It aims for proper understanding of anatomy of the pelvis especially for surgeons. Here are few examples of these questions but the book is uploaded in bulk upload. Bones and joints1.

Pelvic joints and ligaments:a. the sacroiliac joint is a fibrous joint between auricular surfaces of the ilium and sacrumb. the wedge shape of the sacrum contributes to its stabilityc. the coccygeous muscle lies on the pelvic surface of the sacrotuberous ligamentd. the sacrotuberous and sacrospinous ligaments enclose the greater sciatic foramene. the iliolumbar ligament is V-shaped with the apex attached to L510. Pelvic joints and ligamentsa. muscles of pelvis include obturator externus and piriformisb. piriformis arises from the lower third part of the sacrumc. the sigmoid colon becomes the section at the level of the 4th part of the sacrumd. the rectum has no mesenterye. the pelvic brim follows the line of the pubic crest, pectineal line of pubis, iliac crests and ala and promentary of the sacrum11. What bony landmark on the lateral pelvic wall may be used as a reference for localizing female pelvic anatomy or pain phenomena?a. Coccyxb. Ischial spinec. Ischial tuberosityd. Obturator canale. Pectineal line12. All of the following statements concerning the pelvic cavity are correct EXCEPTa. It is bounded posteriorly by the sacrum and coccyx.b. It is bounded anteriorly by the symphysis pubis.c. The pelvic inlet forms the superior boundary.d. The pelvic outlet forms the inferior boundary.e. The musculofascial pelvic diaphragm closes the pelvic inlet.13. All of the following bones contribute to the formation of the pelvic cavity EXCEPTa. ischiumb. pelvisc. pubisd. coccyxe. sacrum14. Which of the following structures is located between the ischial spine and the ischial tuberosity?a. obturator foramenb. lesser sciatic notchc. acetabular notchd. pubic arche. arcuate line15. The lateral part of the superior ramus of the pubis forms which of the following structures?a. iliopubic eminenceb. pubic tuberclec. pecten pubisd. anterior inferior iliac spinee. acetabulum16. All of the following structures are boundaries for the pelvic inlet EXCEPTa. inferior ramus of the pubisb. sacral promontoryc. anterior border of the ala of the sacrumd. arcuate line of the iliume. pecten pubis17. When a person is in the anatomical position, which of the following structures lies in the same vertical plane?a. sacral promontory and pubic tuberclesb. anterior superior iliac spines and the anterior aspect of the pubic symphysisc. posterior superior iliac spines and the posterior aspect of the ischial tuberosityd. ischial spines and the posterior border of the obturator foramene. superior pubic rami and the greater sci- atic notch18. Regarding the female pelvis one statement is incorrect:a. The inlet is oval in shape.b. The inlet longest diameter lies anteroposteriorlyc. All diameters in the mid-passage are 12cm.d. The transverse diameter at the level of the ischial spines is 10.5cm.e. The sacrum is broad, shallow and concave.19. In the female pelvis:a. All diameters are greater than in the male.b. The sub-pubic angle is about 80-85degrees.c. The sacral promontory is less prominent than the male.d. The obturator foramen is triangulare. The male sacrum is broader and shorter than the female.20. Regarding the pelvic skeleton one statement is incorrect:a. It is made up by the innominate bone, the sacrum and the fifth lumbar vertebra.b. The sacrum has five sacral foramina.c. The obturator foramen transmits the obturator nerve and vesselsd. The innominate bone consists of the ilium, pubis and ischium.e. The greater sciatic foramen transmits the piriformis muscle, the superior and inferior gluteal vessels and nerve.21. Which skeletal feature would you consider to be most characteristic of the female pelvis?a. Subpubic angle of 90 degrees or greaterb. Marked anterior curvature of the sacrumc. Tendency to vertical orientation of the iliac bonesd. Prominent medial projection of the ischial spinese. The true conjugate is the antero-posterior diameter of the brim and measures about 10.5cm.22. A 22-year-old victim of an automobile accident received destructive damage to structures that form the boundaries of the perineum. Which of the following structures is spared?a- Pubic arcuate ligamentb- Tip of the coccyxc- Ischial tuberositiesd- Sacrospinous ligamente- Sacrotuberous ligament23. While performing a pelvic exenteration, the surgical oncologist notices a fractured or ruptured boundary of the pelvic inlet. Which of the following structures is most likely damaged?a. Promontory of the sacrumb. Anterior-inferior iliac spinec. Inguinal ligamentd. Iliac creste. Arcuate pubic ligament.24. In order to perform an episiotomy prior to childbirth, the perineum must be anesthetized.

Obturator groovee. Ischial spine25. In your obstetrics rotation, the resident physician asks you to measure the diagonal conjugate of a 23-year old female patient who is hoping to get pregnant. You know that this measurement is between which of the following structures?a. Sacral promontory and coccyxb. Sacral promontory and superior edge of symphysis pubisc. Sacral promontory and inferior edge of symphysis pubisd. Coccyx and ischial spinee. Coccyx and inferior edge of pubic symphysisAnswers 1 b2 d3 d4 c5 e6 b7 e8 a9 d10 d11 b12 e13 a14 b15 b
