Gluteal muscles cover the lateral surfaces of the ilia . The gluteus maximus muscle is the largest and most posterior of the gluteal muscles. Its origin includes parts of the ilium; the sacrum, coccyx, and associated ligaments; and the lumbodorsal fascia. Acting alone, this massive muscle produces extension and lateral rotation at the hip joint. The gluteus maximus shares an insertion with the tensor fasciae latae muscle, which originates on the iliac crest and the anterior superior iliac spine. Together these muscles pull on the iliotibialtract, a band of collagen fibers that extends along the lateral surface of the thigh and inserts on the tibia. This tract provides a lateral brace for the knee that becomes particularly important when you balance on one foot. The gluteus mediusand gluteus minimus muscles originate anterior to the origin of the gluteus maximus muscle and insert on the greater trochanter of the femur. The anterior gluteal line on the lateral surface of the ilium marks the boundary between these muscles. The lateral rotators originate at or inferior to the horizontal axis of the acetabulum. There are six lateral rotator muscles in all, of which the piriformis muscle and the obturator muscles are dominant . The adductors originate inferior to the horizontal axis of the acetabulum. This muscle group includes the adductor magnus, adductor brevis, adductor longus, pectineus, and gracilis muscles. All but the adductor magnus originate both anterior and inferior to the joint, so they perform hip flexion as well as adduction. The adductor magnus muscle can produce either adduction and flexion or adduction and extension, depending on the region stimulated. The adductor magnus muscle may also produce medial or lateral rotation at the hip. The other muscles produce medial rotation. These muscles insert on low ridges along the posterior surface of the femur. When an athlete suffers a pulled groin, the problem is a strain--a muscle tear or break--in one of these adductor muscles. The medial surface of the pelvis is dominated by a pair of muscles. The large psoas major muscle originates alongside the inferior thoracic and lumbar vertebrae, and its insertion lies on the lesser trochanter of the femur. Before reaching this insertion, its tendon merges with that of the iliacus muscle, which nestles within the iliac fossa. These two muscles are powerful hip flexors and are often referred to collectively as the iliopsoas muscle. medical student: Dr.Fofo

Movements of the thigh are accomplished by muscles anchored to the pelvic girdle?

Yes, muscles such as the quadriceps, hamstrings, adductors, and abductors attach to the pelvic girdle and are responsible for moving the thigh. These muscles work together to allow for various movements such as flexion, extension, abduction, adduction, and rotation of the thigh.


Is the pectoral or pelvic girlde lightweight?

The pectoral girdle is typically lighter in weight compared to the pelvic girdle. This is because the pectoral girdle is designed for more flexibility and mobility in upper body movements, while the pelvic girdle provides support and stability to the lower body.


Does the pelvic girdle have tendons?

yes


Why is the pelvic girdle only in the back of your bodies and not over your abdomen area?

The pelvic girdle is located in the back of the body to support the weight of the upper body and to provide stability for movements like walking and running. Placing it over the abdomen area would hinder flexibility and range of motion in the legs and hips. Additionally, having the pelvic girdle in the back allows for the attachment of powerful muscles that aid in posture and movement.


Where is the weight-bearing most important in pectoral or pelvic girdles?

Weight-bearing is most important in the pelvic girdle. The pelvic girdle is located at the base of the spine and pelvis, and it supports the weight of the upper body and provides stability for movements such as walking and standing. In contrast, the pectoral girdle is mainly involved in supporting the arms and shoulders.

The hind limbs on a frog attach to the central skeleton by first attaching to the girdle?

The hind limbs of a frog attach to the central skeleton through the pelvic girdle, specifically the ilium and sacral vertebrae. This connection provides support and allows for efficient movement during activities like jumping and swimming.

In contrast to a male pelvic girdle a female pelvic girdle is?

In comparison to a male pelvic girdle, a female pelvic girdle typically has a wider pelvic inlet and wider pubic angle, allowing for childbirth. Additionally, the female pelvic bones are generally lighter and thinner than those of a male.

The pelvic girdle sacrum and coccyx together form the?

The pelvis. The sacrum and coccyx are part of the human vertebral column, and when connected to the pelvic bones, they form the pelvic girdle, which is also known as the pelvis. This structure supports the spine and provides attachment points for muscles and ligaments.
