Glutei

Glutei

The glutei are a group of three muscles which make up the buttocks: the gluteus maximus, gluteus medius, and gluteus minimus. These muscles are responsible for the movement of the hip and thigh. They are among the strongest muscles in the human body and play a crucial role in maintaining posture and allowing for a range of movements.

Gluteus Maximus

The gluteus maximus is the largest and most superficial of the three gluteal muscles. It is responsible for the movement of the hip and thigh, particularly in actions such as climbing stairs, running, and standing up from a sitting position. The gluteus maximus also helps to maintain the trunk in an erect posture.

Gluteus Medius

The gluteus medius is located on the outer surface of the pelvis. It is partially covered by the gluteus maximus. The primary function of the gluteus medius is to abduct the thigh and stabilize the pelvis during walking and running.

Gluteus Minimus

The gluteus minimus is the smallest and deepest of the gluteal muscles. It lies beneath the gluteus medius. The gluteus minimus works in concert with the gluteus medius to abduct the thigh and stabilize the pelvis.

Function

The glutei are essential for various movements and activities. They are involved in:

• Hip extension
• Hip abduction
• Hip external rotation
• Hip internal rotation

These muscles also play a significant role in maintaining the stability of the pelvis and the alignment of the lower body during activities such as walking, running, and jumping.

Clinical Significance

Weakness or dysfunction in the glutei can lead to various issues, including lower back pain, hip pain, and knee pain. Strengthening the gluteal muscles is often a focus in physical therapy and rehabilitation programs for these conditions.
