Regarding the rectus sheath which of the following statements are true?
Your Answer: Below the arcuate line the transversus divides into two to encompass the rectus abdominus
Correct Answer: Above the arcuate line the internal oblique divides into two lamellae
Explanation:The rectus sheath is formed by the aponeurosis of the internal and external oblique muscles and the transversus abdominus muscle. The internal oblique divides into two lamellae and encloses the rectus muscle. Anteriorly it fuses with the aponeurosis of the external oblique and posteriorly with that of the transverus abdominus. Below the arcuate line the aponeurosis of all the flat muscles lies anteriorly and posteriorly it is only enclosed by the transveralis fascia.

Uterine Cervix:
Your Answer: The cervical canal is covered with stratified squamous epithelium
Correct 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.

Question 7
Correct
-
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.

All of the following anatomical features of the pelvis favour a vaginal delivery, except?
Your Answer: Obstetric conjugate is less than 10 cm
Explanation:For the foetus to pass through the vagina, the obstetric conjugate should be 11cm or greater. If the diameter is less than 10 cm then its better to perform C-section as the labour might not progress. All the other options favour a normal vaginal delivery.

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 roof of the femoral triangle is formed by which structure?
Your Answer: Fascia lata
Explanation:The femoral triangle is bounded:
– Superiorly by the inguinal ligament that forms the base of the femoral triangle.
– Medially by the lateral border of the adductor longus.
– Laterally by the sartorius; the apex of the femoral triangle is formed where the borders of the sartorius and the adductor muscles meet.
– The floor of the femoral triangle is formed by the iliopsoas laterally and the pectineus muscle medially.
– The roof of the femoral triangle is formed by the fascia lata and cribriform
fascia, subcutaneous tissue, and skin. -

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

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

Which of the following statements regarding the Vaginal artery is typically TRUE?
Your Answer: It arises from the Internal iliac artery
Explanation:The Vaginal artery, like the Uterine artery is typically a branch of the Internal Iliac artery. It can sometimes arise as a branch of the Uterine artery so it is important to read the question (if the stem stated it CAN arise from the Uterine artery then that would be true)

Which one of the following statements regarding the fetal head is true?
Your Answer: Considered to be engaged when the biparietal diameter passes the level of the pelvic inlet
Explanation:The fetal head is engaged when the head of the foetus or the presenting part enters the pelvic inlet or pelvic brim. It usually occurs at 38 weeks of gestation.
The Spalding sign refers to the overlapping of the fetal skull bones caused by collapse of the fetal brain. It appears usually a week or more after fetal death in utero.
In brow presentation the scalp is deflexed as the foetus is looking upward. Normally the head is inflexed such that the chin is touching the chest. -

A patient who is 36 weeks pregnant comes to see you as she has developed tingling to the right lateral thigh over the past 3 weeks. On examination there are no skin changes and no muscle weakness. What is the likely diagnosis?
Your Answer: Pudendal nerve entrapment
Correct Answer: Meralgia Paraesthetica
Explanation:Raised pressure with the pelvis can cause a number of nerve entrapment syndromes. This is entrapment of the lateral cutaneous nerve of the thigh (or lateral femoral cutaneous nerve) also known as Meralgia Paraesthetica. Pregnancy is a risk factor. Shingles can effect this nerve but the rash would usually present itself within 14days.
