Regarding molding of the fetal head, which one is true?
Your Answer: Does not happen when the maternal pelvis is adequate
Correct Answer: Does NOT have time to occur in breech delivery
Explanation:Molding allows the skull bones of the fetal head some mobility during the normal delivery of foetus as the skull changes its shape to accommodate passage through the mothers pelvis. However this does not occur in breach delivery where the skull is in circular shape. Babies born breech typically have craniofacial and limb deformations resulting from their in utero position. These babies characteristically have a long, narrow head, (“dolichocephaly” or “type 1”), with a prominent occipital shelf, redundant skin over the neck, overlapping lambdoidal sutures, and an indentation below their ears (from shoulder compression).

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: 3rd type B
Correct 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.

Question 6
Correct
-
From which of the following spinal segments do both the internal and external anal sphincters receive their innervation?
Your 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.

Which of the following takes part in the arterial supply of the ovary?
Your Answer: Uterine arteries
Explanation:The ovarian arteries, arising from the abdominal aorta and the ascending uterine arteries which are branches of the internal iliac artery all supply the ovaries. They terminate by bifurcating into the ovarian and tubal branches and anastomose with the contralateral branches providing a collateral circulation.

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.

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

A patient undergoes surgery for a vaginal vault prolapse. After surgery she complains of numbness of the anterior aspect of the labia. Which nerve has likely been damaged during surgery?
Your Answer: Ilioinguinal
Explanation:The anterior aspect of the vulva (mons pubis, anterior labia) is supplied by derivatives of the lumbar plexus: the anterior labial nerves, derived from the
ilio-inguinal nerve, and the genital branch of the genitofemoral nerve.
The posterior aspect of the vulva is supplied by derivatives of the sacral plexus: the perineal branch of the posterior cutaneous nerve of the thigh laterally, and the pudendal nerve centrally. -

Which two nerves provide the primary cutaneous sensory innervation to the labia majora?
Your Answer: Ilioinguinal and inferior rectal
Correct 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.

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.

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.
