Question 1
Correct
-
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.

Regarding the female breast how many lobes does the typical breast contain?
Your Answer: 15-20
Explanation:The basic components of the mammary gland are the alveoli. These are lined with milk-secreting cuboidal cells surrounded by myoepithelial cells. The alveoli join to form groups known as lobules. The lobules form lobes. Each lobe has a lactiferous duct that drains into openings in the nipple. Each breast typically contains 15-20 lobes.

Presence of which one of the following features at term makes spontaneous delivery incompatible?
Your Answer: Mentum anterior
Correct Answer: Mentum posterior

A vaginal birth at term is possible only if the foetus is in the mentum anterior position.

Regarding the structure of the detrusor muscle. Which of the following is true?
Your Answer: The detrusor is divided into 3 layers consisting of inner and outer layers of longitudinal smooth muscle with a middle circular smooth muscle layer

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

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.

The main support of the uterus is provided by:
Your 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: Pubic symphysis

How many seminiferous tubules would you typically expect to find in a testicular lobule?
Your Answer: 2
Explanation:There are between 250 and 400 lobules in each testis. The lobule is a structural unit of the testis with each lobule contained in one of the intervals between fibrous septa which extend between the mediastinum testis and the tunica albuginea. Each lobule contains 1 to 3 seminiferous tubules.

Which two nerves provide the primary cutaneous sensory innervation to the labia majora?
Your Answer: Ilioinguinal and pudendal
Explanation:The Pudendal provides cutaneous innervation to the posterior external genitalia via one of its terminal branches called the perineal nerve (this further branches into the posterior labial nerves or posterior scrotal nerve in men). The ilioinguinal nerve provides anterior sensation via the anterior labial nerves (anterior scrotal nerve in men). The genital branch of the genitofemoral nerve contributes some fibres to the skin of the mons pubis and labia majora in females. The posterior cutaneous nerve of thigh sometimes overlaps sensory areas.

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 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

Which of the following terms best describes the pelvic type of small posterior sagittal diameter, convergent sidewalls, prominent ischial spines, and narrow pubic arch?
Your Answer: Anthropoid
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.
4) Platypelloid pelvis: in this type the pelvic brim is kidney shape -

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.

Regarding the pelvic outlet, what structure marks the posterior boundary?
Your Answer: Tip of the coccyx
Explanation:The bony pelvis is made up of a girdle with a central canal. The rim that surrounds the upper opening of the canal is called the pelvic inlet, while the lower rim is the called the pelvic outlet. The pelvic outlet is diamond-shaped and is bounded posteriorly by the tip of the sacrum, and anteriorly by the pubic symphysis, with its lateral boundaries being the ischial tuberosities and the sacrotuberous ligament.

What is the inferior border of the deep perineal pouch?
Your Answer: Perineal membrane
Explanation:The perineal membrane (also known as the inferior fascia of the urogenital diaphragm) separates the deep and superficial perineal pouches i.e. it is the inferior border of the deep pouch and superior border of the superficial pouch. The deep perineal pouch is the space therefore between superior and inferior layers of the urogenital diaphragm The superior fascia of the urogenital diaphragm is the superior border
