Inguinal Canal and Spermatic Cord Flashcards
what is in the spermatic cord
-ductus/vas deferens
-testicular artery
- pampiniform plexus of veins > testicular vein
-genitofemoral nerve
-autonomic nerves
-lymphatics
what does the spermatic cord pass through
the inguinal canal
where do gonads develop
upper back in males
what are gonads in the same plane as
peritoneal fat
what muscle are gonads located in
transversalis
what does the gubernaculum do
attaches to gonads in males and females
- has a branch that connects to parietal peritoneum
where is the inguinal hole
inserts of deep surface of skin that ends of bottom of scrotum or labia majora
what does the inguinal hole go through
every layer of tissue/muscle
what are the 3 inguinal rings
deep inguinal ring, middle inguinal ring, superficial inguinal ring
what does the transversalis fascia turn into in the spermatic cord
internal spermatic fascia
what inguinal ring does the transversalis fascia give rise to
deep inguinal ring
what does the transversus abdominal muscle turn into in the spermatic cord
doesnt contribute to spermatic cord or inguinal ring
what does the internal abdominal muscle turn into in the spermatic cord
the cremaster muscle
what inguinal ring does the internal abdominal muscle give rise to
the middle inguinal ring
what does the external abdominal oblique muscle turn into in the spermatic cord
external spermatic fascia
what inguinal ring does the external abdominal oblique muscle give rise to
the superficial inguinal ring`
what is the cremaster muscle and what does it do
it is skeletal muscle that pulls the tests towards the body in thermoregulation
what innervates the cremaster muscle
somatic motor genitofemoral nerve. runs from the ventral ramus
what is the cremaster reflex
scratch inner thigh to see if testes flex in paralyzed patients
what inguinal rings do spermatic cord contents pass through
all 3 of them
what is the processus vaginalis and what does it do
continuation of parietal peritoneum that withers away except near testes
-provides frictionless environment in scrotum for testes to move around
what is the spatial relationship between spermatic cord contents and the processus vaginalis
they run alongide each other
what inguinal rings does the processus vaginalis pass through
all 3
what is the purpose of the venous plexus
thermoregulation of testes
