Kinesiology – The Skeletal System and Muscle Function, 3ed. The contractions of the anterior fibers of the gluteus minimus result into flexion and internal rotation, but the contractions of the posterior fibers result into external rotation of the hip. At the level of the insertion, the tendon of the gluteus minimus is located superficial to the reflected tendon of the rectus femoris and the capsule of the hip joint. A study of its mechanics showed that gluteus minimus acts as a flexor, an abductor and an internal or external rotator, depending on the position of the femur and which part of the muscle is active.

Together: abduction of the hip joint or stabilizes the pelvis relative to the femur, which is used in walking. Reviewer: Reading time: 4 minutes. This is a large area, reaching from the iliac crest above to the almost the sciatic notch below. • The gluteus minimus muscle (plural: glutei minimi) and gluteus medius muscle are two muscles of the more superficial group in the gluteal region.. Summary. How it moves depends on the location of the femur. Moreover, this muscle is an important stabilizer of the pelvis in the gait cycle. The gluteus maximus muscle is the largest gluteal muscle located in the buttocks. The gluteus minimus helps with abduction (movement away from the midline of the body) and medial (inward) rotation of the thigh at the hip. Finally, the tendon inserts onto the anterolateral aspect of the greater trochanter. Function. Like all the other muscles featured on this site, it can get overloaded, tense and develop trigger points. The gluteus minimus, which is responsible for 25% of abduction power, runs in the same plane deep to the gluteus medius. Origin: (proximal attachments) Outer (external) surface of ilium, between the anterior and inferior gluteal lines. When their femoral attachments are fixed, the muscles pull the ipsilateral ilium towards the femur, resulting in the slight ipsilateral pelvic tilt. Gluteus Maximus Appearance 2021 The gluteus medius is located deep to the gluteus maximus, but superficial to the smaller gluteus minimus… While a limb is take off the ground then the pelvis on the opposite side will tending drop through loss of support from below. The gluteus minimus is a small triangular muscle located deep in the posterior region of the hip, spanning from the gluteal surface of the ilium to the proximal end of the femur.

Besides this, the strong tension within these muscles contributes to the stabilization of the pelvis and trunk while walking or standing. A, Standard open-chain action of abduction of the thigh at the hip joint. The distal portion of the muscle and its tendon also receives the contribution from the trochanteric anastomosis; an arterial network formed by the ascending branch of the medial circumflex femoral artery and descending branches of the superior and inferior gluteal arteries.
