Obturator artery
Obturator artery
The Obturator artery (pronunciation: ob-too-ray-tor ar-ter-ee) is a significant blood vessel in the human body that originates from the internal iliac artery. It plays a crucial role in supplying blood to the pelvic muscles and the hip joint.
Etymology
The term "Obturator" is derived from the Latin word "Obturare," which means to close or obstruct. This name is given due to the artery's location near the obturator foramen, a large opening in the hip bone.
Anatomy
The obturator artery typically arises from the anterior division of the internal iliac artery, but variations can occur. It travels along the lateral wall of the pelvis to the obturator foramen, passing through the obturator canal to reach the thigh. Here, it divides into both anterior and posterior branches, supplying blood to the medial compartment of the thigh, the hip joint, and the adductor muscles.
