Origin: (proximal attachments)
Outer surface of ilium, between the posterior and anterior gluteal lines.

Insertion: (distal attachments)
Lateral and superior surfaces of the greater trochanter of femur.

Actions of Gluteus Medius on the thigh (femur):

a. image descriptionAbducts thigh at the hip.

b. Anterior fibers image descriptionMedially Rotate thigh at the hip.

c. Posterior fibers image descriptionLaterally Rotate thigh at the hip.

Nerve to Muscle and its Spinal Segment:

a. Superior gluteal nerve (L5, S1).
