Question

What is the origin, insertion, and innervation of the Hip ER muscle?

1) Origin: internal surface of the anterolateral wall of the pelvis and obturator membrane, Insertion: medial surface of the greater trochanter, Innervation: Nerve to obturator internus
2) Origin: medial surface of the greater trochanter, Insertion: internal surface of the anterolateral wall of the pelvis and obturator membrane, Innervation: Nerve to obturator internus
3) Origin: internal surface of the anterolateral wall of the pelvis and obturator membrane, Insertion: lateral surface of the greater trochanter, Innervation: Nerve to obturator internus
4) Origin: lateral surface of the greater trochanter, Insertion: internal surface of the anterolateral wall of the pelvis and obturator membrane, Innervation: Nerve to obturator internus

Answer 1

The origin, insertion, and innervation of the Hip ER (External Rotator) muscle are defined

Step-by-step explanation:

The origin, insertion, and innervation of the Hip ER (External Rotator) muscle are as follows:

1. Origin: internal surface of the anterolateral wall of the pelvis and obturator membrane
2. Insertion: medial surface of the greater trochanter
3. Innervation: Nerve to obturator internus
