18
Q

Interior abdominal lymphosome

A

Horizontal group of superficial LNs

19
Q

Where does the long saphenous vein run?

A

Medial, anterior to malleolus

20
Q

Indirect vs direct hernia

A

Indirect inguinal hernia: through inguinal canal

Direct inguinal hernia: no regard for anatomy, goes through everything

Femoral canal is tight so femoral hernias are more dangerous

21
Q

Mid point of inguinal ligament

A

Half-way between ASIS and pubic tubercle - superficial ring is at midpoint

22
Q

Mid inguinal point

A

Halfway between ASIS and pubic symphysis - where femoral artery runs

23
Q

Contents of axillary region

A

Biceps brachii, coracobrachialis, BP, axillary artery, axillary vein

24
Q

Borders of axillary region

A

Anterior: pec major and minor
Medial: serrates anterior and thoracic wall
Lateral: intertubecular sulcus
Posterior: scapulars, theres major, lat dorsi
