The outer band

The gluteus maximus (m. gluteus maximus) unbend the thigh, straighten bent forward trunk, pulls a broad fascia of the thigh in the standing position fixes the pelvis and trunk. It is a large, flat, diamond-shaped muscle, which explains the development of a powerful man bipedal locomotion. It starts from the back of the outer (gluteal) surface of the ilium, from the lateral edge of the sacrum and coccyx. Lower beams of muscle attached to the gluteal tuberosity of femur, and is woven into the upper tract podvzdoshnobolshebertsovy. Gluteal tuberosity between the muscle and the trochanteric bag is great gluteal muscle (bursa trochanterica m. giutei maximi).

Average gluteus maximus (m. gluteus medius) assigns the thigh. At the same time rotate the sheaves of the front thigh inward, and back - out. For a fixed position removes hip pelvis to the side. Also involved in straightening bent forward trunk. This is a thick muscle, located under the gluteus maximus, consisting of superficial and deep layers of muscle bundles. Beams themselves are like a fan. Starting point is the muscle on the outer surface of the wing of the ilium, and a broad fascia of the thigh, and the place of attachment - to greater trochanter of the femur. Here is the trochanteric bag middle gluteus muscle (bursa trochanterica m. giutei medii). Small cap muscle (m. gluteus minimus) assigns the thigh and is involved in straightening the body. It covers the middle gluteal muscle, the point of beginning is located on the outer surface of the wing of the ilium between the anterior and the lower gluteal lines. Muscle attached to the front edge of the greater trochanter of the femur.

The muscle fascia stretched wide hips (m. tensor fasciae latae), exerts a broad fascia of the thigh and takes part in its bending. This flat elongated muscle located on the anterolateral surface of the pelvis. It starts from the top front iliac spine and attaches to podvzdoshnobolshebertsovomu tract.

Square thigh muscle (m. quadratus femoris) rotates the thigh outwards. Is rectangular in shape, partly covered up by a large gluteal muscle. It starts from the lateral surface of the ischial tuberosity and is attached to the greater trochanter and intertrochanteric crest of femur. Distal end of the muscle grows into a broad fascia of the thigh.

Upper gemellus (m. gemellus superis), as well as a square, rotate the thigh outwards. Of a muscular bundle, which is the beginning point of the ischial spine on, and place attachment - trochanteric fossa of femur.

Lower gemellus (m. gemellus inferior) rotates the thigh outwards. Start point is the muscle the sciatic tuber and place attachment - trochanteric fossa of the femur.

Outside locking arm (m. obturatorius externum), together with previous muscle rotates the thigh outwards. Muscle is an irregular triangle, the point of beginning is located on the outer surface of the pubic and ischial bones in the locking of the membrane, and the place of attachment is trochanteric fossa of the femur.
