Q

Describe the course and branches of the obturator artery?

A

Passes through the obturator canal to reach the medial compartment of thigh. Gives of anterior and posterior branches.

Anterior - branches to muscles of the medial compartment
Posterior - branches to the muscles attached to the ischial tuberosity

Q

What is the course taken by obturator nerve?

A

Runs along the lateral wall of the pelvis and passes through the obturator canal to enter the thigh
Splits into anterior and posterior branches relative to the adductor brevis

Gives off muscular branches to the medial thigh e.g. branches to the adductors
Anterior branch gives off cutaneous branches to the middle part of the medial thigh
