The abdominal aorta divides to the left and right common iliac artery at the level of ___________.
What is L4?
This specific structure gives an attachment for the biceps femoris and the lateral collateral ligament of the knee
The apex (styloid process) of the head of the fibula
These anterior fibers of the deltoid ligament have a distal attachment of the neck of the talus.
The anterior tibiotalar ligament
What muscle is this?
Origin -
Lateral head: plantar surface of the cuboid and lateral cuneiform
Medial head: tendon of the tibialis posterior
What is the flexor hallucis brevis?
This nerve passes through the psoas major muscle to supply the genitalia
What is the genitofemoral nerve
