What does the circumflex femoral artery supply?
The medial femoral circumflex artery is the primary source of blood supply to the femoral head. A traumatic injury of this vessel may lead to avascular necrosis of the femoral head (AVN). Additionally, this artery supplies the adductors of the hip, obturator externus muscle, hamstrings muscles and sciatic nerve.
Where is the lateral femoral circumflex artery?
upper thigh
The lateral circumflex femoral artery, also known as the lateral femoral circumflex artery, or the external circumflex artery, is an artery in the upper thigh.
What is the largest branch of the lateral femoral circumflex artery?
The main function of the lateral circumflex femoral artery is to supply blood to the hip joint, knee joint, parts of the femur, quadriceps femoris, tensor fasciae latae, as well as skin of the anterolateral aspect of the thigh….Lateral circumflex femoral artery.

What does circumflex artery supply?
The circumflex artery branches off the left coronary artery and encircles the heart muscle. This artery supplies blood to the outer side and back of the heart.
Where is the lateral circumflex?
The lateral circumflex femoral artery is a branch of the profunda femoris that arises from its lateral aspect just after the medial circumflex femoral artery. While the medial circumflex runs posteriorly around the femoral neck, the lateral circumflex courses laterally from its origin and anterior to the femoral neck.
What is circumflex artery?
How deep is the femoral artery in the thigh?
The two bony landmarks useful for identifying the inguinal ligament are the anterior superior iliac spine and pubic symphysis. The average common femoral artery is approximately 4 cm in length and lies just anterior to the femoral head.
Where does the lateral circumflex artery supply blood?
The medial femoral circumflex artery and its branches supply most of the blood to the head and neck of the femur. The lateral femoral artery winds anterolaterally, and the medial femoral artery winds posteromedially around the neck of the femur; they ultimately anastomose with each other at the superolateral aspect of the femoral head.
Where are the extracapsular arteries located in the femur?
Extracapsular arterial ring—formed posteriorly by a large branch of the medial femoral circumflex artery and anteriorly by the lateral circumflex femoral artery, which are branches of the femoral artery or the profunda femoris artery. The extracapsular ring supplies most of the head and neck of the femur.
Which is the smallest branch of the circumflex femoral artery?
Branches. The transverse branch of lateral circumflex femoral artery is a small artery in the thigh. It is the smallest branch of the lateral circumflex femoral artery and passes lateralward over the vastus intermedius, pierces the vastus lateralis, and winds around the femur, just below the greater trochanter,…
What is the function of the deep femoral artery?
The main function of the deep femoral artery is to provide blood supply to the skin of the medial thigh region, proximal femur and muscles that extend, flex and adduct the thigh. This article will discuss the anatomy and function of the deep femoral artery.
