A patient at the time of her second delivery opted for a bilateral pudendal nerve block. In order to inject the anaesthetic agent near the pudendal nerve a anaesthetic consultant had to insert a finger into the vagina and press laterally to palpate which landmark?

Question 3

Which of the following structures lying posterior to the ovary are at risk of injury in excision of a malignant tumour in the right ovary?
Your Answer: Ureter
Explanation:The ovaries are two nodular structures situated one on either side of the uterus in relation to the lateral wall of the pelvis and attached to the back of the broad ligament of the uterus, lying posteroinferiorly to the fallopian tubes. Each ovary has a lateral and medial surface. The ureter is at greater risk of iatrogenic injury at this location.

Question 4

A 38 year old man is to undergo excision of the base of the prostate for malignant growth, which of the following structures is directly related to the base of the prostate?
Your Answer: Urinary bladder
Explanation:The prostate is situated in the pelvic cavity and is also located immediately below the internal urethral orifice at the commencement of the urethra. It is held in position by the puboprostatic ligaments, the superior fascia of the urogenital diaphragm and the anterior portions of the levatores ani. The base of the prostate is directed upward and is attached to the inferior surface of the urinary bladder while the apex is directed downward and is in contact with the superior fascia of the urogenital diaphragm.

Question 5

Which nodes are most likely to be enlarged in a patient complaining of a boil located on the labia majora?
Your Answer: Superficial inguinal
Explanation:The perineum, external genitalia, the labia majora and scrotum drain to the superficial inguinal lymph nodes. In a man, the testes do not drain to the superficial inguinal lymph nodes but rather travel in the spermatic cord and drain into the lumbar nodes. The lumbar nodes drain the internal pelvic organs. The sacral nodes drain the prostrate gland, uterus, vagina, rectum and posterior pelvic wall and the external iliac nodes in turn drain the lower limb. The internal iliac nodes drain the pelvis and gluteal region.

A 60-year old patient presenting with squamous cell carcinoma of the anal canal was brought in to the oncology ward for chemotherapy. In which of the following lymph nodes of this patient would you likely find metastases?
Your Answer: Internal iliac
Explanation:The efferent lymphatics from the anal canal proceed to the internal iliac lymph nodes. This would most likely form the site of enlargement in the lymphatics.

Question 7
Correct
-
Injury to which of the following arteries is likely to affect the blood supply to the seminal vesicles?
Your Answer: Middle rectal
Explanation:Ligation of middle rectal artery is most likely to affect the blood supply of seminal vesicles since arteries supplying the seminal vesicles are derived from the middle and inferior vesical and middle rectal arteries.

Question 8
Correct

An episiotomy is indicated for a woman during a difficult vaginal delivery. Whilst the registrar was performing this procedure she made a median cut too far through the perineal body cutting the structure immediately posterior. Which structure is this?
Your Answer: External anal sphincter
Explanation:An episiotomy is an incision that is made whenever there is a risk of a tear during vaginal deliver. A posterolateral incision, as opposed to a median incision is preferred. Of the options given, the external anal sphincter lies right posterior to the perineal body. The sacrospinous and the sacrotuberous ligaments are deep in the perineum that they should not be involved in this.

Question 9

Which name is given to the inferior fascia of the urogenital diaphragm?
Your Answer: Perineal membrane
Explanation:The urogenital fascia is mostly commonly referred to as the perineal membrane. This term refers to an anatomical fibrous membrane in the perineum. It is triangular in shape, and thus at times referred to as the triangular ligament. It is about 4 cm in depth. Its The perineal membrane’s apex is anterior and is separated from the arcuate pubic ligament by an oval opening for the passage of the deep dorsal vein of the penis. The lateral marginas of this triangular ligament are attached on either side to the inferior rami of the pubis and ischium, above the crus penis. Its base faces the rectum, and connects to the central tendinous point of the perineum. The pelvic fascia and Colle’s fascia is fused to the base of this triangle.

Which lymph nodes are most likely to enlarge due to the spread of infection through the lymphatic channels in a patient with a boil on his scrotum?
Your Answer: Superficial inguinal nodes
Explanation:The superficial inguinal nodes drain the perineum and the external genitalia which include the scrotum and the labia majora. The testes, however, drain to the lumbar nodes.

What is formed when the ductus deferens unites with the duct of the seminal vesicle?
Your Answer: Ejaculatory duct
Explanation:The deferens is a cylindrical structure​ with dense walls and an extremely small lumen It is joined at an acute angle by the duct of the seminal vesicles to form the ejaculatory duct, which traverses the prostate behind it’s middle lobe and opens into the prostatic portion of the urethra, close to the orifice of the prostatic utricle.

Prostatectomy carries a risk of loss of penile erection due to injury to the prostatic plexus responsible for an erection. From which nerves do these fibres originate?
Your Answer: Pelvic splanchnics
Explanation:Erection is a function of the parasympathetic nerves. Of the nerves listed, only the pelvic splanchnic nerves have parasympathetic fibres that innervate the smooth muscles and glands of the pelvic viscera.

The following structures DO NOT lie between the layers of the mesosalpinx except for the?

During hysterectomy, the ureter is most likely to be ligated when a surgeon is clamping the?
Your Answer: Uterine tubes
Correct Answer: Uterine arteries
Explanation:The ureter forms the posterior boundary of a shallow depression which lodges the ovary and then runs medially and forward on the lateral aspect of the uterine cervix and upper part of the vagina to reach the fundus of the bladder. It is also situated about 2cm from the side of the cervix of the uterus. The relationship of the ureters and uterine arteries is of clinical significance because the arteries are at risk of iatrogenic injury during hysterectomy.

Question 17

-
Where do the seminal vesicles lie?
Your Answer: Base of the bladder and rectum
Explanation:The seminal vesicles are two lobulated membranous pouches situated between the fundus of the bladder and rectum and act as a reservoir for the semen and secrete a fluid that is added to the seminal fluid. Each sac is pyramidal in shape but they all vary in size not only in different individuals but also in the same individuals. The anterior surface is in contact with the fundus of the bladder, extending from near the termination of the ureter to the base of the prostate. Each vesicle consist of single tube, which gives off several irregular caecal diverticula. These separate coils and the diverticula are connected by fibrous tissue.

What forms the pelvic diaphragm?
Your Answer: Levator ani and coccygeus muscles
Explanation:The pelvic diaphragm is formed by the levator ani and the coccygeus muscles. The levator ani forms the greater part of the pelvic floor supporting the viscera in the pelvic cavity.

The principal motor and sensory nerve of the perineum is the?
Your Answer: Pudendal
Explanation:The pudendal nerve is formed by S1,2,4 anterior branches. It gives off the inferior haemorrhoid nerve before dividing terminally into the perineal nerve and the dorsal nerve of the clitoris or the penis. Thus, it is the principal motor and sensory nerve of the perineum.
