Q

What supplies the cremaster muscle and where does that artery come from?

A

artery of the cremaster muscle and comes from the inferior epigastric which is a branch of the external iliac

21
Q

Where do the testicular veins originate from?

A

Pampiniform venous plexus

22
Q

How are variscosities formed in the pampiniform venous plexus?

A

defective valves in the testicular veins

usually on left side due to increased pressure in the left renal vein

23
Q

What is orchitis and what can it lead to?

A

inflammation of the glandular tissue within the testes

can lead to sterility

24
Q

What is a Varicocele and how is it most likely caused? is left cause different from right?

A

enlargement of the veins of the spermatic cord

Left– most likely cause is an obstruction of the left renal vein

Right– most likely cause is obstruction of the right testicular vein

25
Q

What does the superior vesical artery supply?

A

superior aspect of the bladder and portion of the vas deferens

26
Q

What does the inferior vesical artery supply?

A 
neck of the bladder
prostate
seminal vesicles
ejaculatory duct
the ampulla of the vas deferens
27
Q

What are the 4 branches of the internal pudendal artery?

A

Posterior scrotal artery
perineal arteries
dorsal arteries of the penis
deep arteries of the penis–supply erectile tissue of the corpora cavernosa by way of their helicine branches

28
Q

What does the deep dorsal vein receive blood from and where does it drain?

A

receives the venous return from the corpora cavernosa

drains into the prostatic venous plexus and vesicle plexus terminating in the internal iliac veins

29
Q

What nerves provide primary sensory supply to the glans penis and erectile tissue?

A

Dorsal nerves

30
Q

What nerve conveys sensory information from the root of the penis?

A

ilioinguinal nerve (L1)

31
Q

What is contained within the fluid produced by the spinal vesicles?

A 
Fructose
prostaglandins
ascorbic acid
simple sugars
amino acids
32
Q

What communication establishes a viable route for spread of infection from the prostate to the brain?

A

inferior portions of the prostatic plexus communicates with the internal vertebral venous plexus

33
Q

What nerve fibers are responsible for erection?

A

Pelvic splanchnic nerves–parasympathetic fibers

34
Q

How do surgeons avoid impotency by cutting the prostatic nerve plexus?

A

Transurethral resection of the prostate TURP–removing the disease portion of the prostate through the urethra

35
Q

What fibers are responsible for generating the urge to urinate?

A

visceral afferent fibers traveling with pelvic splanchnic nerves

36
Q

What nerve fibers cause contraction of the smooth muscle of the bladder?

A

pelvic splanchnic nerves

37
Q

What muscle fibers relax allowing urination and what nerve fibers innervate this muscle?

A

Pubococcygeous muscle innervated by somatic motor fibers from the pudendal nerve (S2-S4)

38
Q

What nerve fibers cause peristaltic activity in the large bowel and when it reaches the rectum what nerve fibers a stimulated to cause simulation to defecate?

A

Pelvic splanchnic nerves cause peristaltic activity and the visceral afferent fibers traveling with the pelvic splanchnic nerves give perception of fullness

39
Q

What muscles relax to allow for defecation?

A

Puborectalis muscle

internal and external sphincters innovated by pudendal nerve

40
Q

What nerves send efferent signals to initiate vasodilation of the spongy ere tile tissue and stimulation of secretory activity in the bulbourethral glands?

A

Pelvic splanchnic nerves–preganglionic parasympathetic and visceral afferents

41
Q

With continued afferent input what nerve fibers are activated?

A

Lumbar splanchnic nerves–Pre/postganglionic (after synapsing in inferior mesenteric and hypogastric ganglia) sympathetic and visceral afferents

42
Q

What expels the semen through the penile urethra and what innervates these muscles?

A

rhythmic contractions of the bulbospongiosus and ischiocavernosus muscles–pudendal nerve somatic motor fibers

43
Q

What two mechanisms are important for sperm production?

A

Evaporation and countercurrent heat exchange

44
Q

What covering comes form the Parietal Peritoneum

A

Tunica Vaginalis

45
Q

What covering comes from the Transversalis Fascia

A

Internal Spermatic Fascia

46
Q

What covering comes from the Internal Abd. Obl. M.

A

Cremaster m./ Middle Spermatic Fascia

47
Q

What covering comes from the External Abd. Obl. M

A

External Spermatic Fascia

48
Q

What covering comes from the Scarpa’s Fascia

A

Colle’s Fascia

49
Q

What covering comes from the Superficial Fascia

A

Dartos Muscle
