HIP ABDUCTOR MUSCLES
The hip abductor muscles are a group of four muscles located in the buttocks region on both sides of the body. Their names are: 1) Gluteus Maximus, 2) Gluteus Medius, 3) Gluteus Minimus, and 4) Tensor Fascia Lata. These muscles are shown in Figure 1 below:
Figure 1. The Hip Abductor Muscles.
INNERVATION (NERVE SUPPLY)
The nerve supply to the abductor muscles is as follows: The Gluteus Maximus is supplied by the Inferior Gluteal Nerve and branches from the Sacral Plexus. The Gluteus Medius, Gluteus Minimus, and Tensor Fascia Lata are supplied by the Superior Gluteal Nerve. See Figure 2 below:
Figure 2. Nerves of the Abductor Muscles.
