Termination of deep branch of medial circumflex femoral artery
Describe the course of the medial circumflex femoral artery.
- leaves femoral triangle by passing between PECTINEUS and PSOAS MAJOR
- continues posteriorly between OBTURATOR EXTERNUS and ADDUCTOR BREVIS
- finally reaches between QUADRATUS FEMORIS and upper border of ADDUCTOR MAGNUS where it will give off its transverse and descending branches
