1

where do the testes and epididymis receive innervation from?

the testicular plexus

2

what is the testicular plexus?

a network of nerves derived from the renal and aortic plexi

3

aside from the testicular plexus, what else do the testes and epididymis receive in terms of innervation?

they receive autonomic and sensory fibres

4

what is the arterial supply to the testes and epididymis via?

the paired testicular arteries

5

where do the paired testicular arteries arise?

directly from the abdominal aorta

6

where are the testicular arteries' course of travel?

They descend down the abdomen, and pass into the scrotum via the inguinal canal, contained within the spermatic cord

7

venous drainage of testicles and scrotum?

paired testicular veins

8

what are the paired testicular veins formed from?

They are formed from the pampiniform plexus in the scrotum

9

what is the pampiniform plexus in the scrotum?

a network of veins wrapped around the testicular artery

10

where does the left testicular vein drain in the abdomen?

drains into the left renal vein

11

where does the right testicular vein drain in the abdomen?

directly into the inferior vena cava

12

what is the lymphatic drainage of the testes?

paired lumbar and para-aortic nodes, located at the L1 vertebral level

13

where are the paired lumbar and para-aortic nodes located?

L1 vertebral level

14

what is the lymphatic drainage of the scrotum?

into the nearby superficial inguinal nodes

15

what is a feature of the scrotal sac?

very distensible

16

what does distensibility of the scrotal sac mean?

it will enlarge in response to the size of its contents

17

what are the most common causes of scrotal swelling?

Inguinal hernia
Hydrocoele
Haematocoele
Varicocoele
Epididymitis

18

what is an inguinal hernia? (causes scrotal swelling)

contents of the abdominal cavity protrude into the scrotum, via the inguinal canal

19

what is a hydrocoele? (causes scrotal swelling)

a collection of serous fluid within the tunica vaginalis

20

what is a hydrocoele most commonly due to? (causes scrotal swelling)

failure of the processus vaginalis to close

21

what is a haematocoele? (causes scrotal swelling)

a collection of blood in the tunica vaginalis

22

how can a haematocoele be distinguished from a hydrocoele?

by transillumination

23

what is transillumination? (distinguish between haematocoele and hydrocoele)

where a light is applied to the testicular swelling

24

what happens in haematocoele during a transillumination?

Due to the dense nature of blood, light is unable to pass through

25

what is Varicocoele?

gross dilation of the veins draining the testes

26

which testicle is more affected in varicocoele?

The left testicle is more commonly affected

27

why is the left testicle more affected in varicocoele?

the left testicular vein drains into a smaller vessel, the left renal vein, at a perpendicular angle

28

what can a large varicocoele look and feel like?

a bag of worms within the scrotum

29

what is Epididymitis?

inflammation of the epididymis

30

causes of Epididymitis?

inflammation of the epididymis, usually caused by bacterial or viral infection
