Regarding the urinary bladder, what type of epithelium lines it?
Your Answer: Transitional
Explanation:The urinary bladder, and most of the urinary structures are lined by epithelium called the urothelium, or the transitional epithelium. This stratified lining is divided into three parts, an apical layer, an intermediate layer and a basal layer. The transitional epithelium is available to stretch to accommodate the increased volume when the bladder is distended, without structural damage.

At the time of delivery, if there is a laceration of perineal body but not the anal sphincter, this type of laceration is classified as?
Your Answer: Second degree
Explanation:Perineal tears are common at the time of child birth. First degree perineal laceration means that the wound is so small that it doesn’t require any stitches and usually heals on its own. 2nd degree means that skin and smooth muscles are both torn. 3rd degree tear means that the tear is beyond the perineal muscles and the muscles surrounding the anal canal, while in 4th degree, the perineal tear goes through the anal sphincter up to the rectum.

The typical female breast contains how many lobes?
Your Answer: 15-20

Question 4

During vertex presentation, the position is determined by relationship of which part of the fetal vertex to the mother's pelvis?
Your Answer: Occiput
Explanation:A cephalic presentation is the one where head of the foetus enters the pelvic cavity at the time of delivery. The commonest form of cephalic presentation is the vertex presentation in which the occiput of the foetus enters the birth canal.

Question 5
Incorrect
-
Under which one of the following conditions is the pelvic inlet felt to be contracted?
Your Answer: The anterio-posterior diameter is only 12 cm
Correct Answer:
Explanation:Contracted pelvis occurs when one or more of its diameters is reduced so that it interferes with the normal mechanism of labour. A transverse diameter below 11 cm will result in difficult delivery of the foetus and C-section will be the better option in that case

Question 6
Correct
-
All of the following anatomical features of the pelvis favour a vaginal delivery, except?
Your Answer: Obstetric conjugate is less than 10 cm
Explanation:For the foetus to pass through the vagina, the obstetric conjugate should be 11cm or greater. If the diameter is less than 10 cm then its better to perform C-section as the labour might not progress. All the other options favour a normal vaginal delivery.

Which spinal segment is the lumbar plexus derived from?
Your Answer: L1-L5
Correct Answer: T12-L4
Explanation:The lumbar plexus is formed via contributions from the T12-L4 spinal cord segment. The plexus is responsible for the motor and sensory innervation of portions of the lower extremities and some parts of the lower abdomen and pelvis. Nerves arising from the plexus include the Iliohypogastric, ilioinguinal, genitofemoral, lateral femoral cutaneous, femoral nerve, obturator, and nerve to the lumbosacral trunk.

What is the anterior boundary of the pelvic outlet?
Your Answer: ischial tuberosity
Correct Answer: pubic arch
Explanation:The pelvic outlet is bounded anteriorly by the inferior border of the pubic arch, posteriorly by the sacrotuberous ligament and the tip of the coccyx and laterally by the ischial tuberosities.

Question 9
Incorrect
-
What is the anatomical landmark used for gauging the station of the fetal head during labour?
Your Answer: Pubic arch
Correct Answer: Ischial Spine
Explanation:The ischial spine is the anatomical landmark for assessing the station of the fetal head and also placing pudendal nerve blocks. (the pudendal nerve runs posterior to the ischial spine). The ischial spine can be palpated approximately 8cm into the vagina, at 4 and 8 o’clock.

Which of the following leaves the pelvis via the greater sciatic foramen?
Your Answer: Obturator Nerve
Correct Answer: Pudendal Nerve
Explanation:The pudendal nerve arises from the S2-S4 nerve roots and it lies medial to the internal pudendal artery while exiting the pelvis via the greater sciatic foramen. It curves around the sacrospinous ligament and re-enters the pelvis via the lesser sciatic foramen and from there it runs medial to the ischial tuberosity over the obturator internus in the pudendal canal to the deep perineal pouch.
