Joints

The hip joint represents the connection between thigh and hip (Articulatio coxae). It is a nut joint, a special form of the ball joint. The head of the joint is clearly more than halfway in the acetabulum.

The socket (acetabulum) is formed by the pelvis, the joint head is the head of the femur (caput femoris). The hip can be moved in this joint The joint between the thigh and the lower leg (knee joint) is a bicondylar joint.This means that the joint surface is formed by two condyles of the thigh (medial and lateral) and the two condyles of the tibia. In this joint

Bent (flexion) and
Slight stretching (extension). Furthermore, the thigh can be
Induced (adduction) or
Are led away (abduction).
Slight turning movements inwards and outwards are also possible.
Diffraction (flexion),
Stretching (extension), and
Rotary movements (internal and external rotation).

Vessels of the thigh

The large abdominal aorta (aorta abdominalis) divides in the pelvis into the right and left common pelvic arteries (arteria iliaca communis dextra and sinistra). The vessels of the internal iliac artery supply the buttocks and thigh. The A. iliaca externa is the source of the large femoral artery (Arteria femoralis).

This branches out into numerous smaller and larger branches and supplies both the deep and superficial areas of the leg. Branches also extend to the genital region. The venous system is divided into superficial and deep veins.

The deep large veins run approximately parallel to the corresponding arteries and have the same names. The largest superficial vein is the vein saphena magna. It receives the blood from numerous other superficial veins and finally conducts it in the groin area into the deep vein femoralis. All other superficial veins are also connected to the deep veins via smaller bridging veins and thus conduct the blood from the periphery back to the trunk.

External (externna) and a
Inner (internal) pelvic artery.
