SESSION 5 - Inguinal Canal And Spermatic Cord
1. From your knowledge of the attachments of the abdominal wall muscles:
(a) What is the position of the deep inguinal ring in relation to the inguinal
ligament?
(b) The deep ring is a hole in which fascia?
(c) What muscle makes the immediate lateral border to the deep ring?
(d) What two muscle lie immediately anterior to the deep ring?
(e) What blood vessel lies just medially to the deep ring?
2. We see that there are two muscles anterior to the deep ring to give it strength
and protection. What two muscles lie posterior to the superficial ring for
similar purposes?
3. Concerning the boundaries of the inguinal canal
(a) The floor is the … … … … … ligament
(b) The roof is curved fibres of the … … … … … muscle and the … … … … .
muscle
(c) The lateral third of the anterior wall is the … … … oblique and the
… … … oblique. More medially the anterior wall is the .… … … ...
oblique only
(d) The posterior wall is … … … … fascia and the … … … … tendon
4. In an indirect inguinal hernia from where does the peritoneal sac emerge?
5. In a direct hernia there is weakness of which tissue?
6. Which hernia is medial and which lateral to the inferior epigastric vessels?
7. Clinically, how would decide between these two hernias?
8. Which of these structures passes through the deep inguinal ring
(a) Genital branch of the genitofemoral nerve
(b) Processus vaginalis
(c) Ilio-inguinal nerve
(d) Inferior epigastric artery
(e) Cremasteric artery
(f) Artery to the vas
(g) Round ligament of the uterus
(h) Ligament of the ovary
9. Which of these structures lie in the inguinal canal
(a) Ilio-inguinal nerve
(b) External spermatic fascia
(c) Internal spermatic fascia
(d) Vas deferens
(e) Testicular artery
(f) Pampiniform plexus
(g) Cremasteric muscle
10. What clinical condition occurs when there is a continuous small leak of
peritoneal fluid down a patent processus vaginalis?
11. What clinical condition occurs when there is a wide open patent processus
vaginalis?
12. The contents of the spermatic cord are easily remembered when listed like
this. Can you name the structures?
(a) Three arteries (where do they originate?)
(b) Three veins
(c) Three nerves
(d) Three fasciae
(e) Three other structures
13. From you knowledge of referred pain in the abdomen where would you feel
the sensation of a kicked testis? Would it be lateralised to one or other side?
14. What is the name of the immediate, moderately thick covering of the testis?
15. Is the appendix of the testis a remnant of the paramesonephric duct or the
mesonephric duct?
16. Is the appendix of the epididymis a remnant of the paramesonephric duct or
the mesonephric duct?
17. Does the testis have a parasympathetic supply?
18. What are the boundaries of the femoral canal? When a femoral hernia is
irreducible which boundary can be cut with little risk? If a blood vessel is
damaged during this procedure which one is it likely to be?
19. How long is the vas? To help you, here are other structures that are the same
approximate length: the femur, the transverse colon, teeth to cardia of
stomach, spinal cord, thoracic duct!
