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.

Which nerves innervate the internal anal sphincter?
Your Answer: Pelvic Splanchnic
Explanation:The anal sphincters are responsible for closing the anal canal to the passage of faeces and flatus. The smooth muscle or 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 the rectus sheath which of the following statements are true?
Your Answer: Above the arcuate line the internal oblique divides into two lamellae

The juxtaglomerular apparatus (JGA) lies within which part of the kidney?
Your Answer: Renal Medulla
Correct 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.

After a vaginal delivery, a patient suffers a perineal tear. On examination the laceration involves the external anal sphincter and has partially torn the internal anal sphincter. Which of the following classifies this tear?
Your Answer: 3b
Correct Answer: 3c
Explanation:During childbearing the vagina and perineum are prone to lacerations that may involve the skin or can extend into the anal sphincter complex. It is important to be able to identify obstetric and anal sphincter injuries to provide adequate care and prevent complications. In the classification of obstetric tears according to RCOG guidelines:
First degree tear: injury to the perineal skin and/or the vaginal mucosa
Second degree tears: Injury to perineum involving perineal muscles but not the anal sphincter.
Third-degree tear: Injury to perineum involving the anal sphincter complex:
Grade 3a tear: Less than 50% of external anal sphincter (EAS) thickness torn.
Grade 3b tear: More than 50% of EAS thickness torn.
Grade 3c tear: Both EAS and internal anal sphincter (IAS) torn.
Fourth-degree tear: Injury to perineum involving the anal sphincter complex (EAS and IAS)
and anorectal mucosa. -

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. -
