Q

What is the difference between the crural fibers and ligaments of inguinal canal?

A

Lacunar/pectinate ligaments attach inguinal ligament to pubic bone

Crural fibers are etensions of aponeurosis that form the boundary of superficial inguinal ring

A

testicular cancer

28
Q

Abdominal muscle layers make up testicle/ spermatic cord EXCEPT?

A

External spermatic fascia

32
Q

What is in the spermatic cord?

A

Vas deferens
testicular A and V
——->pampiniform plexus
gonadal N and lymph

33
Q

What is a testicular varicocele?

A

Varicosities of pampiniform plexus

——>swelling in scrotum with dull and recurring pain

34
Q

What is a persistent processus vaginalis?

A

patent connection b/t tunica vaginalis and abdomen

35
Q

What is a hydrocele?

A

peritoneal fluid accumulated within tunica vaginalis

36
Q

What is a hematocele?

A

accumulation of blood in tunica vaginalis

37
Q

What is the tunica albuginea?

A

directly covers testes, covered by visceral layer of tunica vaginalis

38
Q

How do you detect hydrocele vs hematocele?
