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.

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: Third degree
Correct 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.

You are asked to assess a patients perineal tear following labour by vaginal delivery. You note a laceration that extends approximately a quarter of the thickness through the external anal sphincter. How would you classify this tear?
Your Answer: 2nd
Correct Answer: 3a
Explanation:1. First-degree trauma corresponds to lacerations of the skin/vaginal epithelium alone.
2. Second-degree tears involve perineal muscles and therefore include episiotomies.
3. Third-degree extensions involve any part of the anal sphincter complex (external and internal sphincters):
i Less than 50 per cent of the external anal
sphincter is torn.
ii More than 50 per cent of the external anal
sphincter is torn.
iii Tear involves the internal anal sphincter
(usually there is complete disruption of the
external sphincter).
4. Fourth-degree tears involve injury to the anal sphincter complex extending into the rectal mucosa. -

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. -

Question 10

-
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.

Regarding molding of the fetal head, which one is true?
Your 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).

During the filling phase of micturition. At what bladder volume is the first urge to void felt?
Your Answer: 150ml
Explanation:Micturition is defined as a process of expelling urine from the body. It is caused by the reflex contraction of detrusor muscle. Urinary bladder is a hollow muscular organ which can store 400-600ml of urine until it is expelled from the body. The first urge to urinate is felt when the bladder is filled with around 150ml of urine. The reflex action is initiated when the stretch receptors located in the bladder wall are stimulated. The afferent fibres pass to the pelvic splanchnic nerves to the 2nd, 3rd, and 4th sacral segments and some pass through the hypogastric plexus to the first and second lumbar segments of the spinal cord. Efferent pathways from the 2nd, 3rd, and 4th sacral segments leave the cords and through the splanchnic nerves and inferior hypogastric plexus supplies the smooth muscle of the bladder i.e. detrusor muscle. Detrusor muscle contracts and the sphincters are relaxed.

Bladder neck closure and relaxation of the bladder is mediated by?
Your Answer: Parasympathetic Fibres T11,L1,L2
Correct Answer: Sympathetic Fibres L1,L2
Explanation:The neck of the bladder is surrounded by the internal sphincter. It is supplied by the sympathetic and parasympathetic nerves of the splanchnic nerve. Parasympathetic stimulation causes the detrusor muscle to contract and the internal urethral sphincter to relax. It Is predominantly by the parasympathetic nerves S2-S4. Relaxation of the bladder is caused by inhibiting the sacral parasympathetic preganglionic neurons and exciting the lumbar sympathetic preganglionic neurons. Remember SYMPATHETIC is for STORAGE and PARASYMPATHETIC is for PEEING.
