1

what are the contents of the spermatic cord?

testicular artery
Cremasteric artery and vein
Artery to the vas deferens
Pampiniform plexus of testicular veins
Genital branch of the genitofemoral nerve
Vas deferens
Lymph vessels
Processus vaginalis
Autonomic nerves

2

what is testicular artery a branch of?

a branch of the aorta

3

where does testicular artery arise?

just inferiorly to the renal arteries

4

what do the Cremasteric artery and vein supply?

supplies the cremasteric fascia and muscle

5

what is Artery to the vas deferens a branch of?

a branch of the inferior vesicle artery

6

where does Artery to the vas deferens arise from?

the internal iliac

7

what does the Pampiniform plexus of testicular veins drain?

drains venous blood from the testes into the testicular vein

8

what does the Genital branch of the genitofemoral nerve supply?

supplies the cremaster muscle

9

what is the vas deferens?

duct that transports sperm from the epididymis to the ejaculatory ducts, ready for ejaculation

10

where do the lymph vessels of the scrotum drain into? location?

the para-aortic nodes, located in the lumbar region

11

what is processes vaginalis?

a projection of peritoneum that forms the pathway of descent for the testes during embryonic development

12

how do the processes vaginalis present in adults?

In the adult, it is fused shut

13

what is the pampiniform plexus?

a network of veins, responsible for the venous drainage of the testes

14

location of pampiniform plexus?

wrapping itself around the testicular artery

15

when do the testes function best?

at a temperature just below that of the body

16

what is the function of the pampiniform plexus?

acts as a heat exchanger, cooling the arterial blood before it reaches the testes

17

where does the pampiniform plexus travel through?

through the inguinal canal

18

what happens as the pampiniform plexus travels through the inguinal canal?

the pampiniform plexus condenses into a single testicular vein

19

where does the right testicular vein drain into?

inferior vena cava

20

where does the left testicular vein drain into?

left renal vein

21

what is the vas deferens?

a straight, thick muscular tube

22

function of the vas deferens?

conveys sperm from the epididymis to the ejaculatory duct

23

what is vas deferens formed by?

the convergence of the vas deferens and seminal vesicle duct

24

after sperm has been passed from epididymis --> vas deferens --> ejaculatory duct, where does it then pass to?

From the ejaculatory duct, sperm can pass through to the urethra

25

what do the wall of the vas deferens contain?

a smooth muscle coat

26

how many layers are there to the smooth muscle coat of wall of vas deferens and what are they?

3 layers:
inner layer of longitudinal muscle
intermediate layer of circular muscle
outer layer of longitudinal muscle

27

what is the innervation to the SM coat o wall of vas deferns?

There is a rich autonomic innervation of these muscle fibres

28

what does the rich autonomic innervation of SM fibres of vas deferens allow for?

permits fast movement of sperm towards the ejaculatory duct

29

what is the vas deferens continuous with?

tail of the epididymis

30

where does vas deferens travel through?

the inguinal canal
