Gluteal

Gluteal refers to the muscles found in the buttocks. These muscles are known as the gluteus maximus, gluteus medius, and gluteus minimus. They are one of the strongest muscles in the human body and play a crucial role in maintaining the upright posture of the body.

Anatomy

The gluteal region is located posterior to the pelvic girdle and extends distally to the thigh. It is primarily composed of the three gluteal muscles: the gluteus maximus, gluteus medius, and gluteus minimus. These muscles originate from the ilium and sacrum and insert on the femur.

Gluteus Maximus

The gluteus maximus is the largest and most superficial of the gluteal muscles. It is responsible for the movement of the hip and thigh. Standing up from a sitting position, climbing stairs, and maintaining an erect posture are all aided by the gluteus maximus.

Gluteus Medius

The gluteus medius is located beneath the gluteus maximus and is the primary internal rotator of the hip. It also assists in hip abduction and medial rotation.

Gluteus Minimus

The gluteus minimus is the smallest and deepest of the gluteal muscles. It assists in hip abduction and medial rotation, similar to the gluteus medius.

Function

The gluteal muscles play a crucial role in maintaining the upright posture of the body. They are involved in numerous actions including extension, abduction, external and internal rotation of the hip joint.

Clinical Significance

Injury or strain to the gluteal muscles can result in gluteal pain or sciatica. Conditions such as piriformis syndrome can also affect the gluteal region.
