Bladder contraction during voiding (micturating) is mediated via innervation of which of the following pathways?
Your Answer: Parasympathetic fibres from L4,L5,S1 nerve roots
Correct Answer: Parasympathetic fibres from S2,S3,S4 nerve roots
Explanation:Detrusor contraction is via Parasympathetic innervation of pelvic splanchnic nerves (S2-4). This also causes relaxation of the internal urethral sphincter Note contraction and relaxation of the external urethral sphincter is under somatic control.

The arcuate line forms part of the border of the pelvic brim. Where is it located?
Your Answer: Ilium
Explanation:Arcuate means ‘bow shaped’ and there are different arcuate lines in anatomical terms. Regarding the pelvic brim this is composed of the arcuate line of the ilium, pectineal line and prominences of sacrum and pubic symphysis (as demonstrated in the images below). As can be seen the arcuate line is a smooth rounded border on the internal surface of the ilium inferior to the iliac fossa and Iliacus. Image sourced from Wikipedia Note: The pelvic outlet is also called the inferior aperture. The pelvic brim is the superior aperture

A patient is about to undergo a pudendal nerve block after vaginal delivery to repair an episiotomy. Which spinal segments form the pudendal nerve?
Your Answer: S1 and S2
Correct Answer: S2, S3 and S4
Explanation:The pudendal nerve provides sensory innervation to regions of the anus, the perineum, the labia and the clitoris in women. The nerve is formed from the ventral rami of the S2-S4 sacral spinal nerves. The nerve is paired, each innervating the left and the right side of the body. Pudendal nerve blocks are indicated for analgesia of the second stage of labour, repair of an episiotomy or perineal laceration, and for minor surgeries of the lower vagina and perineum.

Regarding the uterine artery which of the following statements are TRUE?
Your Answer: It arises from the internal iliac artery
Explanation:The uterine artery arises from the internal iliac artery, in particular the anterior division of the internal iliac artery. Some older texts refer to the internal iliac as the hypogastric artery. The vaginal artery typically arises as its own branch of the internal iliac artery. The ovarian arteries are branches of the aorta

Regarding the uterine artery which of the following statements are FALSE?
Your Answer: Typically anastomoses with branches of the Ovarian artery
Correct Answer: It crosses the Ureter posteriorly
Explanation:The Uterine artery typically arises from the anterior branch of the internal iliac artery. It crosses the ureter ANTERIORLY. It is the primary source of arterial supply to the uterus and its branches anastomose with branches of the ovarian and vaginal arteries.

You are asked to assess a patients perineal tear following labour by vaginal delivery. You note a laceration that extends through the vaginal mucosa into the perineal muscle and fascia. The external anal sphincter appears to be in tact. How would you classify this tear?
Your Answer: 2nd
Explanation:If the external anal sphincter is in tact then this is a 1st or 2nd degree tear. As the perineal muscles are involved this is 2nd degree tear.

The main support of the uterus is provided by:
Your Answer: The broad ligament
Correct Answer: The cardinal ligament
Explanation:The cardinal ligament (or Mackenrodt’s ligament, lateral or transverse cervical ligament) is a major ligament of the uterus. It is located at the base of the broad ligament of the uterus. It attaches the cervix to the lateral pelvic wall by its attachment to the Obturator fascia of the Obturator internus muscle, and is continuous externally with the fibrous tissue that surrounds the pelvic blood vessels. It thus provides support to the uterus.

What is the anatomical landmark used for gauging the station of the fetal head during labour?
Your Answer: Iliac Spine
Correct Answer: Ischial Spine
Explanation:The ischial spines and palpable through the vagina and are used as landmarks to assess the decent of the fetal head from the cervix. It also serves as a landmark for giving the pudendal block.

The vulva is mainly supplied by which one of the following vessels?
Your Answer: Pudendal artery
Explanation:Vulva is defined by the area which is located outside the female vagina and comprises of the labia majora, labia minora, clitoris, mons pubis and Bartholin glands. It is supplied by the vestibula branch of pudental artery.
Inferior hemorrhoidal artery supplies the lower part of the rectum.
Femoral artery is the continuation of external iliac artery and supplies most of the leg. -

What is the average anteroposterior distance of the female pelvic outlet?
Your Answer: 11.5 cm
Correct Answer: 13 cm
Explanation:The pelvic outlet is bounded in front by the lower margin of the symphysis pubis, on each side by the descending ramus of the pubic bone, the ischial tuberosity and the sacrotuberous ligament, and posteriorly by the last piece of the sacrum. The AP diameter of the pelvic outlet is 13.5 cm and the transverse diameter is 11 cm.

Regarding lymph drainage of the fallopian tubes where does the majority of lymph drain to?
Your Answer: External iliac nodes
Correct Answer: Para-aortic nodes
Explanation:Lymphatic vessels from the ovaries, joined by vessels from the uterine tubes and most from the fundus of the uterus, follow the ovarian veins as they ascend to the right and left lumbar (caval/aortic) lymph nodes.
