1
Q

what are the contents of the spermatic cord?

A
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
Q

what is testicular artery a branch of?

A

a branch of the aorta

3
Q

where does testicular artery arise?

A

just inferiorly to the renal arteries

4
Q

what do the Cremasteric artery and vein supply?

A

supplies the cremasteric fascia and muscle

5
Q

what is Artery to the vas deferens a branch of?

A

a branch of the inferior vesicle artery

6
Q

where does Artery to the vas deferens arise from?

A

the internal iliac

7
Q

what does the Pampiniform plexus of testicular veins drain?

A

drains venous blood from the testes into the testicular vein

8
Q

what does the Genital branch of the genitofemoral nerve supply?

A

supplies the cremaster muscle

9
Q

what is the vas deferens?

A

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

10
Q

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

A

the para-aortic nodes, located in the lumbar region

11
Q

what is processes vaginalis?

A

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

12
Q

how do the processes vaginalis present in adults?

A

In the adult, it is fused shut

13
Q

what is the pampiniform plexus?

A

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

14
Q

location of pampiniform plexus?

A

wrapping itself around the testicular artery

15
Q

when do the testes function best?

A

at a temperature just below that of the body

16
Q

what is the function of the pampiniform plexus?

A

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

17
Q

where does the pampiniform plexus travel through?

A

through the inguinal canal

18
Q

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

A

the pampiniform plexus condenses into a single testicular vein

19
Q

where does the right testicular vein drain into?

A

inferior vena cava

20
Q

where does the left testicular vein drain into?

A

left renal vein

21
Q

what is the vas deferens?

A

a straight, thick muscular tube

22
Q

function of the vas deferens?

A

conveys sperm from the epididymis to the ejaculatory duct

23
Q

what is vas deferens formed by?

A

the convergence of the vas deferens and seminal vesicle duct

24
Q

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

A

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

25
Q

what do the wall of the vas deferens contain?

A

a smooth muscle coat

26
Q

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

A

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

27
Q

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

A

There is a rich autonomic innervation of these muscle fibres

28
Q

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

A

permits fast movement of sperm towards the ejaculatory duct

29
Q

what is the vas deferens continuous with?

A

tail of the epididymis

30
Q

where does vas deferens travel through?

A

the inguinal canal

31
Q

where does vas deferens move through?

A

lateral pelvic wall in close proximity to the ischial spine

32
Q

what happens after vas deferens has moved through lateral pelvic wall in close proximity to the ischial spine?

A

Turns medially to pass between the bladder and the urethra

33
Q

what happens after the vas deferens has turned medially to pass between the bladder and the urethra?

A

Joins the duct from the seminal vesicle to form the ejaculatory duct
