Which of the following leaves the pelvis via the greater sciatic foramen?
Your 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.

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

Uterine Cervix:
Your Answer: Is the portion of the uterus below the isthmus
Explanation:The uterus is divisible into two portions. The portion above the isthmus is termed the body, and that below, the cervix. The uterine cervix is the narrow inferior segment of the uterus, which projects into the vaginal cavity. It is a fibromuscular organ lined by a mucous membrane and measures approximately 3cm in length and 2.5cm in diameter. The cervix is continuous at its superior margins with the body of the uterus and at its inferior margins with the vagina.

A patient is about to undergo a pudendal nerve block after vaginal delivery to repair an episiotomy. Which spinal segments form the pudendal nerve?
Your Answer: S2, S3 and S4
Explanation:The pudendal nerve provides sensory innervation to regions of the anus, the perineum, the labia and the clitoris in women. The nerve is formed from the ventral rami of the S2-S4 sacral spinal nerves. The nerve is paired, each innervating the left and the right side of the body. Pudendal nerve blocks are indicated for analgesia of the second stage of labour, repair of an episiotomy or perineal laceration, and for minor surgeries of the lower vagina and perineum.

The juxtaglomerular apparatus (JGA) lies within which part of the kidney?
Your Answer: Renal Cortex
Explanation:The substructures of the nephrons are mainly located within the cortex. The JGA sits next to the glomerulus in the cortex (click on the magnifying glass of the image to see the arrangement). They play an important role in blood pressure homeostasis as the juxtaglomerular cells produce renin. The descending and ascending limbs of the loop of Henle and collecting ducts have sections within both the cortex and medulla

Bladder contraction during voiding (micturating) is mediated via innervation of which of the following pathways?
Your Answer: Parasympathetic fibres from L4,L5,S1 nerve roots
Correct Answer: Parasympathetic fibres from S2,S3,S4 nerve roots
Explanation:Detrusor contraction is via Parasympathetic innervation of pelvic splanchnic nerves (S2-4). This also causes relaxation of the internal urethral sphincter Note contraction and relaxation of the external urethral sphincter is under somatic control.

Bladder neck closure and relaxation of the bladder is mediated by?
Your Answer: Sympathetic Fibres S2,S3,S4
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.

The inguinal canal is reinforced posteriorly by which structure?
Your Answer: Conjoint tendon
Explanation:The Inguinal Canal
– Anterior wall: formed by the external oblique aponeurosis throughout the length of the canal; its lateral part is reinforced by muscle fibres of the internal oblique.
– Posterior wall: formed by the transversalis fascia; its medial part is reinforced by pubic attachments of the internal oblique and transversus abdominis aponeuroses that frequently merge to variable extents into a common tendon—the inguinal falx (conjoint tendon)—and the reflected inguinal ligament.
– Roof: formed laterally by the transversalis fascia, centrally by musculo-aponeurotic arches of the internal oblique and transversus abdominis, and medially by the medial crus of the external oblique aponeurosis.
– Floor: formed laterally by the iliopubic tract, centrally by gutter formed by the infolded inguinal ligament, and medially by the lacunar ligament. -

What is the average anteroposterior distance of the female pelvic outlet?
Your Answer: 11.5 cm
Correct Answer: 13 cm
Explanation:The pelvic outlet is bounded in front by the lower margin of the symphysis pubis, on each side by the descending ramus of the pubic bone, the ischial tuberosity and the sacrotuberous ligament, and posteriorly by the last piece of the sacrum. The AP diameter of the pelvic outlet is 13.5 cm and the transverse diameter is 11 cm.

Regarding the Pituitary gland which of the following statements is true?
Your Answer: It is surrounded by the sella turcica
Explanation:The Sella turcica is composed of three parts:
1. The tuberculum sellae (horn of saddle): a variable slight to prominent median elevation forming the posterior
boundary of the prechiasmatic sulcus and the anterior boundary of the hypophysial fossa.
2. The hypophysial fossa (pituitary fossa): a median depression (seat of saddle) in the body of the sphenoid that accommodates the pituitary gland (L. hypophysis).
3. The dorsum sellae (back of saddle): a square plate of bone projecting superiorly from the body of the sphenoid.
It forms the posterior boundary of the Sella turcica, and its prominent superolateral angles make up the posterior clinoid processes. -

The rectus sheath is formed by which of the following?
Your Answer: aponeuroses of transversus abdominis, external and internal oblique
Explanation:The rectus sheath is formed by the decussation and interweaving of the aponeuroses of the fl at abdominal muscles. The external oblique aponeurosis contributes to the anterior wall of the sheath throughout its length. The superior two thirds of the internal oblique aponeurosis splits into two layers (laminae) at the lateral border of the rectus abdominis; one lamina passing anterior to the muscle and the other passing posterior to it. The anterior lamina joins the aponeurosis of the external oblique to form the anterior layer of the rectus sheath. The posterior lamina joins the aponeurosis of the transversus abdominis to form the posterior layer of the rectus sheath.
