The following statements describe different muscles and their location:
- The erector spinae: located in the lower back, between the iliac crest and the 12th rib.
- The external rotators: found on the outside of the pelvis, surrounding the acetabulum.
- The internal rotators: found on the inner side of the upper arm, between the shoulder and elbow.
- The adductors: located in the inner thighs, near the knee.
- The abductors: found in the outer thighs.
The erector spinae is responsible for maintaining the natural curvature of the spine, while the external rotators and internal rotators work together to rotate the hip and thigh muscles. The adductors are involved in moving the thighs towards the midline of the body, and the abductors assist in moving the legs away from the midline of the body.
