Anatomy of the nerves and blood vessels of the anterior thigh: origin, course, and termination
Origin and anatomical course of the femoral artery
The femoral artery originates from the external iliac artery, courses through the anterior thigh, and terminates as the popliteal artery. It plays a vital role in lower limb circulation.
Anatomy of the Nerves and Blood Vessels of the Anterior Thigh
Origin and Anatomical Course of the Femoral Artery
The femoral artery is the primary blood vessel supplying the anterior thigh. It originates from the external iliac artery and transitions into the femoral artery as it passes beneath the inguinal ligament.
Origin
The femoral artery arises from the external iliac artery at the level of the inguinal ligament. This transition marks the beginning of its course through the thigh.
Anatomical Course
- Proximal Segment: Begins at the inguinal ligament and enters the femoral triangle.
- Mid-Thigh Course: Travels deep to the sartorius muscle within the adductor canal.
- Distal Segment: Becomes the popliteal artery after passing through the adductor hiatus.
Termination
The femoral artery terminates as it exits the adductor canal and enters the popliteal fossa, where it continues as the popliteal artery.
Clinical Significance
The femoral artery is crucial for lower limb circulation and is commonly used for catheterization procedures. Its superficial location makes it accessible for medical interventions.
