Thigh
The thigh is the part of the lower extremity linking at the Man the basin with the leg. Its function is primarily locomotor.
In the edible birds, such as the Chicken or the Turkey, the thigh is one of the rear limbs of the animal, in opposition to the wings.
Anatomical structure
Osseous
The Fémur is the Os of the thigh, the longest bone of the human and particularly resistant Squelette because of the forces of bearing pressure which it has to support. Like all the long bones, one distinguishes a body (diaphyse) and two ends (épiphyse) to him. The crâniale end is called the head of the femur. It is connected to the body by the coll. The head: 2/3 of sphere of an average diameter of 35 Misters Recouverte with articular cartilage, it is the place of insertion of the triangular ligament. (which connects the femur to the iliaque bone) The collar: spindle-shaped One observes the large one and the lesser trochanter. One distinguishes on the posterior face from the femoral body the rough line. Place of insertion of many muscles The distal end is made up of the two femoral condyles. Condyles which are articulated with the tibia and the patella (old kneecap) to form the articulation of the knee
Vascular
The thigh offers passage to large arterial blood-vessels and Veine ux:- Arteries: femoral Artery, deep Artery of the thigh, perforating arteries
- Veins: Vein large saphene and Vein small saphene under the skin, femoral Vein located against the artery
Nervous
The Nerve sciatic nerve and its branches innerve muscles of the thigh, before becoming Nerve tibial in the area of the Knee.
Muscular
The muscles of the thigh are divided into three cabins: the former cabin, the posterior cabin and the internal cabin.The former cabin is occupied by:
- the Tensor muscle of the fascia lata
- Muscle sartorius (or muscle dressmaker)
- Muscle femoral quadriceps:
- former Right
- Vast médial
- Vast side
- Vast intermediary
The internal cabin, formed by the muscles supply mains :
- pectinate Muscle
- Muscle gracile (in the past Internal rights)
- Muscle long supply main
- Muscle short supply main
- Muscle large supply main
- Muscle femoral biceps
- Muscle semi-tendineux
- semi-membranous Muscle
Elements of private clinic and pathology
The thigh is studied easily on a stripped individual. The examination of the two thighs is comparative .Clinically, one seeks a Amyotrophie by the measurement of the tower of the thigh to the meter ribbon, one seeks a Parésie by the operation of Mingazzini.
The search for painful muscular points in a sportsman, as of the painful movements evoking a Diminishes a elongation a muscular Déchirure a muscular Hématome.
-
the femur is accessible to the standard radiological examination.
- the arteries and the veins are explored by injection of product of contrast. (arteriography and phlebography)
- the muscles are explored by echography and IRM.
