The muscles on the top of the hip bone, specifically the ilium, are primarily the gluteal muscles. These muscles are essential for hip movement, stability, and overall lower body function.
Gluteal Muscles
The gluteal group comprises the following muscles:
-
Gluteus Maximus: The largest and most superficial of the gluteal muscles. It is primarily responsible for hip extension and external rotation. It also plays a role in thigh abduction.
-
Gluteus Medius: Located beneath the gluteus maximus, this muscle is crucial for hip abduction and stabilization of the pelvis during walking and running.
-
Gluteus Minimus: The smallest and deepest of the gluteal muscles, it assists the gluteus medius in hip abduction and internal rotation.
-
Tensor Fasciae Latae (TFL): Although not directly part of the "gluteus" group, the TFL originates near the hip bone (ilium) and contributes to hip flexion, abduction, and internal rotation. It also stabilizes the knee.
These gluteal muscles cover the lateral surface of the ilium, contributing significantly to the shape and function of the hip and surrounding area.
