The nerve of the anterior compartment of thigh is the femoral nerve. [2] Innervation for the quadriceps muscles come from the posterior division of the femoral nerve, while the anterior division (which contains cutaneous as well as muscular components) gives a lateral and a medial branch, the second being responsible for the innervation of the sartorius muscle. [4]
The medial femoral circumflex artery (with its branches) supplies arterial blood to several muscles, including: the adductor muscles of the hip, gracilis muscle, [1] [3] pectineus muscle, [3] and external obturator muscle. [1] It delivers most of the arterial supply to the femoral head and femoral neck via branches - the posterior retinacular ...
The pectineus muscle is the most anterior adductor of the hip. The muscle's primary action is hip flexion; it also produces adduction and external rotation of the hip. It can be classified in the medial compartment of thigh [2] (when the function is emphasized) or the anterior compartment of thigh (when the nerve is emphasized). [3]
Posterior view of several hip muscles Anterior view of several hip muscles Posterior view of gluteus maximus and gluteus medius. In human anatomy, the muscles of the hip joint are those muscles that cause movement in the hip. Most modern anatomists define 17 of these muscles, although some additional muscles may sometimes be considered.
The anterior branch runs downward on the sartorius, perforates the fascia lata at the lower third of the thigh, and divides into two branches: one supplies the integument as low down as the medial side of the knee; the other crosses to the lateral side of the patella, communicating in its course with the infrapatellar branch of the saphenous nerve.
The external obturator muscle or obturator externus muscle (/ ˌ ɒ b tj ʊəˈr eɪ t ər ɪ k ˈ s t ɜːr n ə s /; OE) is a flat, triangular muscle, which covers the outer surface of the anterior wall of the pelvis. It is sometimes considered part of the medial compartment of thigh, [1] and sometimes considered part of the gluteal region. [2]
The sartorius muscle originates from the anterior superior iliac spine, [4] and part of the notch between the anterior superior iliac spine and anterior inferior iliac spine. It runs obliquely across the upper and anterior part of the thigh in an inferomedial direction. [3] It passes behind the medial condyle of the femur to end in a tendon.
The adductor longus is in relation by its anterior surface with the pubic portion of the fascia lata, and near its insertion with the femoral artery and vein. By its posterior surface with the adductor brevis and magnus , the anterior branches of the obturator artery , vein , and nerves , and near its insertion with the profunda artery and vein .
