Which bone contains the greater trochanter?
The greater trochanter of the femur is a large, irregular, quadrilateral eminence and a part of the skeletal system. It is directed lateral and medially and slightly posterior. In the adult it is about 2-4 cm lower than the femoral head.
Where is the gluteal tuberosity found?
femur
The gluteal tuberosity is the lateral ridge above the linea aspera of the femur. It is the site of insertion of the gluteus maximus muscle.
What is attached to the greater trochanter?
The greater trochanter is the attachment site for five muscles: the gluteus medius, gluteus minimus, piriformis, obturator externus, and obturator internus.
Which muscle has part of its insertion on the gluteal tuberosity?
Gluteus maximus muscle
| Origin | Lateroposterior surface of sacrum and coccyx, gluteal surface of ilium (behind posterior gluteal line), thoracolumbar fascia, Sacrotuberous ligament |
|---|---|
| Insertion | Iliotibial tract, gluteal tuberosity of femur |
Where is the deltoid tuberosity?
humerus
The deltoid tuberosity of the humerus lies proximally about a third of the way to the elbow and provides an attachment point for the deltoid muscle. The deltoid is a triangular muscle with three attachment points: the humerus, the clavicle, and the scapula.
What is the trochanter of the femur?
A trochanter is a tubercle of the femur near its joint with the hip bone. In humans and most mammals, the trochanters serve as important muscle attachment sites. Humans are known to have three trochanters, though the anatomic “normal” includes only the greater and lesser trochanters.
Is the greater trochanter the hip bone?
There are two major bursae in the hip that typically become irritated and inflamed. One bursa covers the bony point of the hip bone called the greater trochanter. Inflammation of this bursa is called trochanteric bursitis.
Which gluteal muscle inserts somewhere other than trochanter?
| SUPERFICIAL MUSCLES OF THE GLUTEAL REGION | ||
|---|---|---|
| Muscle | Origin | Insertion |
| Gluteus minimus | External surface of ilium between anterior and inferior gluteal lines | Anterior surface of greater trochanter of femur |
| Tensor fasciae latae | Anterior superior iliac spine; anterior portion of iliac crest | Iliotibial tract |
What is a tuberosity in anatomy?
Tuberosity – A moderate prominence where muscles and connective tissues attach. Its function is similar to that of a trochanter. Examples include the tibial tuberosity, deltoid tuberosity, and ischial tuberosity. Tubercle – A small, rounded prominence where connective tissues attach.
Which bones have a tuberosity?
The tubercle is much more prominent in the upper ribs than in the lower ribs. The most prominent tubercle of the tibia, a leg bone which is more commonly known as the shinbone or shankbone, is the tibial tuberosity. The tibial tuberosity is located on the tibia’s anterior surface, distal to the medial condyle.
