Which one of the following muscles is the most important muscle forming the pelvic floor?
Your Answer: Levator ani
Explanation:Levator ani muscle is composed of three different muscles i.e. iliococcygeus, pubococcygeus and the puborectalis muscle. It is the main muscle that supports the organs of the pelvic cavity.
Bulbocavernosus and Ischiocavernosus muscles are located in-between the anus and scrotum and play an important role in sexual response in males.
Superficial and deep transverse perineal muscles are located in the perinium and pass in front of the anus. -

Your Answer: Gynecoid
Correct Answer: Android
Explanation:There are four types pelvic shapes:
1) Android pelvis: it has a larger inlet and smaller outlet along with small posterior sagittal diameter, prominent ischial spines and has a two finger arch.
2) Gynecoid pelvis: it has a transverse or nearly a circular ellipse and it is the most favourable for delivery.
3) Anthropoid pelvis: the brim is an anteroposterior ellipse.

Sensory supply to the clitoris is via branches of which nerve?
Your Answer: Pudendal nerve
Explanation:The pudenal nerves has three branches, namely the inferior rectal, perineal and the dorsal nerve of the clitoris. The perineal nerve has two branches: The superficial perineal nerve gives rise to posterior scrotal or labial (cutaneous) branches, and the deep perineal nerve supplies the muscles of the deep and superficial perineal pouches, the skin of the vestibule, and the mucosa of the inferior most part of the vagina. The inferior rectal nerve communicates with the posterior scrotal or labial and perineal nerves. The dorsal nerve of the penis or clitoris is the primary sensory nerve serving the male or female organ, especially the sensitive glans at the distal end.

From which of the following spinal segments do both the internal and external anal sphincters receive their innervation?
Your Answer: S3
Correct Answer: S4
Explanation:The anal sphincters are responsible for closing the anal canal to the passage of faeces and flatus. The smooth muscle of the involuntary internal sphincter sustains contraction to prevent the leakage of faeces between bowel movements and is innervated by the pelvic splanchnic nerves, which are a branch of the spinal segment 4. The external sphincter is made up of skeletal muscle and can therefore contract and relax voluntarily. Its innervation comes from the inferior rectal branch of the pudendal nerve, and the perineal branch of S4 nerve roots.

Presence of which one of the following features at term makes spontaneous delivery incompatible?
Your Answer: Occiput anterior
Correct Answer: Mentum posterior
Explanation:When face presentation is diagnosed, around 60% of cases are in the mentum anterior position, 25% are mentum posterior and 15% are mentum transverse; most malpositions rotate spontaneously into mentum anterior. A vaginal birth at term is possible only if the foetus is in the mentum anterior position.

The arterial blood supply to the bladder is via branches of which artery?
Your Answer: Inferior epigastric artery
Correct Answer: Internal Iliac

Sensory supply to the clitoris is via branches of which nerve?
Your Answer: Perineal
Correct Answer: Pudendal nerve
Explanation:The Pudendal nerve divides into inferior rectal, perineal and dorsal nerve of the clitoris (or penis in males). The dorsal nerve of clitoris supplies sensory innervation to the clitoris. The perineal branch supplies sensory innervation to the skin of the labia majora and minora and the vestibule.

Which of the following leaves the pelvis via the greater sciatic foramen?
Your Answer: Pudendal Nerve
Explanation:The pudendal nerve is formed by sacral nerve roots S2, S3 and S4 almost immediately as they exit the spinal foramina. The pudendal nerve exits the pelvis via the greater sciatic foramen, travels behind the sacrospinous ligament before re-entering the pelvis via the lesser sciatic foramen. It is an important nerve to be aware of as it supplies sensation to the genitalia and can also be damaged/compressed at a number of places along its course. Image sourced from Wikipedia

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.
