Subinguinal hiatus
borders:
a) Inguinal ligg.
b) sup.ramus Pubic bone (iliopubic eminence-pubic tubercle)
Er divided by iliopectineal arch into–>
a) lacuna musculorum (laterally)
þar er, iliopsoas, femoral n og lateral cut. femoral n
b) lacuna vasorum (medially)
þar er, femoral br of genitofemoral og femoral vessels

Femoral triangle contents
1) Laterally - femoral nerve
-Ant. cut. rr: skin, anterior femoral reg
-Muscular rr: PISQ
-Saphenous n: skin medial leg/foot dorsum
2) Middle - femoral artery
- external pudendal aa
- superficial epigastric
- superficial circumflex iliac
- deep femoral a (laterally from femoral A)–>
‘medial c.flex femoral
‘lateral c.flex femoral
‘perforating aa
3) Medially - femoral vein
drains blood from structures from Femoral A
-great saphenous vein - spf structures medial lower limb
Adductor canal
borders:
laterally- vastus medialis m.
medially- adductor longus og adductor magnus
ventrally- vastoadductor membrane
*contents:
-femoral A - (og desc, genicular branch)
-femoral V
-femoral N (og infrapatellar branch)
Adductor hiatus
-distal end of adductor canal
(add.canal cont. in popliteal fossa
-pierces adductor magnus
-contents: popliteal A + V (cont. of femoral A+V)
Obturator canal
borders: inf. margin sup ramus pubic bone + obt.membrane
*contents:
