The medius muscle is shaped like a cap. Its anterior fibers act as a medial rotator and flexor; the posterior fibers as a lateral rotator and extensor; and the entire muscle abducts the hip. The minimus has similar functions and both muscles are inserted onto the greater trochanter. [17] Muscles of the hip
The human genome consists of two copies of each of 23 chromosomes (a total of 46). [1] One set of 23 comes from the mother and one set comes from the father. [1] Of these 23 pairs of chromosomes, 22 are autosomes, and one is a sex chromosome. [1]
The quadriceps femoris muscle is subdivided into four separate muscles (the 'heads'), [1] [2] with the first superficial to the other three over the femur (from the trochanters to the condyles): The rectus femoris muscle occupies the middle of the thigh, covering most of the other three quadriceps muscles. [1] It originates on the ilium. It is ...
The hip flexors are (in descending order of importance to the action of flexing the hip joint): [2] Collectively known as the iliopsoas or inner hip muscles: Psoas major; Iliacus muscle; Anterior compartment of thigh. Rectus femoris (part of the quadriceps muscle group) Sartorius; One of the gluteal muscles: Tensor fasciae latae; Medial ...
The femur (/ ˈ f iː m ər /; pl.: femurs or femora / ˈ f ɛ m ər ə /), [1] [2] or thigh bone, is the only bone in the thigh — the region of the lower limb between the hip and the knee. In many four-legged animals the femur is the upper bone of the hindleg .
The quadratus femoris is a flat, quadrilateral skeletal muscle. Located on the posterior side of the hip joint, it is a strong external rotator and adductor of the thigh, [2] but also acts to stabilize the femoral head in the acetabulum. The quadratus femoris is used in Meyer's muscle pedicle grafting to prevent avascular necrosis of femur head.
The other two borders of the femur are only slightly marked: the lateral border extends from the antero-inferior angle of the greater trochanter to the anterior extremity of the lateral condyle; the medial border from the intertrochanteric line, at a point opposite the lesser trochanter, to the anterior extremity of the medial condyle.
The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body. [1] The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle) can be
