27
Q

Inferior Epigastric vessels

A

branch off the external iliac artery deep to the rectus abdominus

28
Q

Superior Epigastric Vessels

A

terminal branch of the internal thoracic artery

29
Q

Inferior and superior epigastric vessels

A

anastomise with each other to supply blood to lower limbs if descending aorta is compromised
become enlarged to handle increased blood flow

30
Q

what are the umbilical folds

A

the inferior epigastric vessels coursing between the transversalis fascia and the parietal peritoneum, causing a fold in the pertineum

Where is the T10 dermatome

A

umbilicus

34
Q

Where is the L1 dermatome

A

The inguinal fold

35
Q

Anterior Superior Iliac Spine

A

bony projection from the iliac crest

inguinal ligament attaches

36
Q

Pubic tubercle

A

projection on the upper medial portion of superior ramus of pubis

37
Q

What are the Inguinal triangles boundaries

A

Inferior: Inguinal ligament
Superolaterally: Inferior Epigastric vessels
Medially: lateral border of rectus abdominus

38
Q

Inguinal Canal

A

Passageway for structures to and from the scrotum

From the Deep inguinal ring to the superficial inguinal ring

39
Q

Superficial inguinal ring

A

gap in external oblique located superior to the pubic tubercle

40
Q

Deep inguinal ring

A

evagination of the transversalis fascia

41

42
Q

What keeps arterial blood cooler before reaching the testis

A

the pampiniform plexus of veins

43
Q

What is the al dente spaghetti in the spermatic cord

dartos fascia is continuous with Scarpa’s fascia

crinkles scrotum to help protect in cold

47
Q

A

located in inguinal canal

anchors uterus to the labium majus (labia majora)

48
