Which spinal segment is the lumbar plexus derived from?
Your Answer: T12-L4
Explanation:The lumbar plexus is formed via contributions from the T12-L4 spinal cord segment. The plexus is responsible for the motor and sensory innervation of portions of the lower extremities and some parts of the lower abdomen and pelvis. Nerves arising from the plexus include the Iliohypogastric, ilioinguinal, genitofemoral, lateral femoral cutaneous, femoral nerve, obturator, and nerve to the lumbosacral trunk.

What are the branches of the pudendal nerves in women?
Your Answer: Perineal, inferior anal and dorsal nerve of clitoris
Explanation:The pudendal nerve provides sensory and motor 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. The nerve gives the following branches in females: the inferior anal nerve, the perineal nerve and the dorsal nerve of the clitoris.

Question 9
Correct
-
The main support of the uterus is provided by:
Your Answer: The cardinal ligament
Explanation:The cardinal ligament (or Mackenrodt’s ligament, lateral or transverse cervical ligament) is a major ligament of the uterus. It is located at the base of the broad ligament of the uterus. It attaches the cervix to the lateral pelvic wall by its attachment to the Obturator fascia of the Obturator internus muscle, and is continuous externally with the fibrous tissue that surrounds the pelvic blood vessels. It thus provides support to the uterus.

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 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.

Correct
-
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 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.

Question 20
Correct
-
Sensory supply to the clitoris is via branches of which nerve?
Your Answer: Pudendal nerve
Explanation:The pudenal nerves has three branches, namely the inferior rectal, perineal and the dorsal nerve of the clitoris. The perineal nerve has two branches: The superficial perineal nerve gives rise to posterior scrotal or labial (cutaneous) branches, and the deep perineal nerve supplies the muscles of the deep and superficial perineal pouches, the skin of the vestibule, and the mucosa of the inferior most part of the vagina. The inferior rectal nerve communicates with the posterior scrotal or labial and perineal nerves. The dorsal nerve of the penis or clitoris is the primary sensory nerve serving the male or female organ, especially the sensitive glans at the distal end.

The uterine vein drains where?
Your Answer: Internal iliac vein
Explanation:The venous drainage of the uterus is via the uterine veins which form a plexus passing below the artery within the base of the broad ligament communicating with the rectal and the vesical venous plexus before draining into the internal iliac veins.

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.

The typical female breast contains how many lobes?
Your Answer: 15-20
Explanation:The female breast is made of about 15 to 20 individual lobes. The lobules each consists of alveoli which drain into a single lactiferous duct. The ductal system leads to lactiferous sinuses and collecting ducts which expel milk from openings in the nipple.

Regarding the uterine artery which of the following statements are TRUE?
Your Answer: It arises from the internal iliac artery
Explanation:The uterine artery arises from the internal iliac artery, in particular the anterior division of the internal iliac artery. Some older texts refer to the internal iliac as the hypogastric artery. The vaginal artery typically arises as its own branch of the internal iliac artery. The ovarian arteries are branches of the aorta

Regarding lymph drainage of the breast where does the majority of lymph drain to?
Your Answer: Axillary nodes
Explanation:Lymphatic drainage of the breast.
The lateral two thirds of the breast drains into the axillary lymph nodes. This constitute about 75% of the lymphatic drainage of the breast. The medial third of the breast drains into the parasternal lymph nodes and these communicate with the ipsilateral lymph nodes from the opposite breast. The superior part of the breast drains into the infraclavicular lymph nodes and inferior part drains into the diaphragmatic lymph nodes. -

What is the inferior border of the deep perineal pouch?
Your Answer: Superior fascia of the urogenital diaphragm
Correct 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
