Under which one of the following conditions is the pelvic inlet felt to be contracted?
Your Answer: Pelvic shape is platypelloid
Correct Answer:
Explanation:Contracted pelvis occurs when one or more of its diameters is reduced so that it interferes with the normal mechanism of labour. A transverse diameter below 11 cm will result in difficult delivery of the foetus and C-section will be the better option in that case

Which two nerves provide the primary cutaneous sensory innervation to the labia majora?
Your Answer: Ilioinguinal and pudendal
Explanation:The Pudendal provides cutaneous innervation to the posterior external genitalia via one of its terminal branches called the perineal nerve (this further branches into the posterior labial nerves or posterior scrotal nerve in men). The ilioinguinal nerve provides anterior sensation via the anterior labial nerves (anterior scrotal nerve in men). The genital branch of the genitofemoral nerve contributes some fibres to the skin of the mons pubis and labia majora in females. The posterior cutaneous nerve of thigh sometimes overlaps sensory areas.

Regarding the uterine artery which of the following statements are TRUE?
Your Answer: It arises from the vaginal artery
Correct 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

Which spinal segment is the lumbar plexus derived from?
Your Answer: T10-L5
Correct 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.

Regarding the female breast how many lobes does the typical breast contain?
Your Answer: 4
Correct 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.

A patient present to the clinic with a 1 day history of vaginal prolapse. Upon examination, the vagina is 1.5 cm below the vaginal plane. What grade is the prolapse according to the POP-Q classification?
Your Answer: Grade 2
Correct Answer: Grade 3
Explanation:Pelvic organ prolapse is a common condition amongst ageing women where a weakness in the pelvic support structures of the pelvic floor allows pelvic viscera to descend.
The Pelvic Organ Prolapse Quantification system (POP-Q) is useful for describing and staging the severity of the pelvic organ prolapse.
Grade 1: the most distal portion of the prolapse is more than 1 cm above the level of the hymen
Grade 2: the most distal portion of the prolapse is 1 cm or less proximal or distal to the hymenal plane
Grade 3: the most distal portion of the prolapse protrudes more than 1 cm below the hymen but protrudes no farther than 2 cm less than the total vaginal length (for example, not all of the vagina has prolapsed)
Grade 4: vaginal eversion complete -

Which one of the following muscles is the most important muscle forming the pelvic floor?
Your Answer: Bulbo cavernousus
Correct Answer: Levator ani
Explanation:Levator ani muscle is composed of three different muscles i.e. iliococcygeus, pubococcygeus and the puborectalis muscle. It is the main muscle that supports the organs of the pelvic cavity.
Bulbocavernosus and Ischiocavernosus muscles are located in-between the anus and scrotum and play an important role in sexual response in males.
Superficial and deep transverse perineal muscles are located in the perinium and pass in front of the anus. -

What is the inferior border of the deep perineal pouch?
Your Answer:
Correct Answer: Perineal membrane
Explanation:The perineal membrane is a tough fascial sheet that attaches to the sides of the urogenital triangle. it forms the inferior border of the deep pouch which lies between this and the levator ani and the superior border of the superficial pouch.
