Hip Abduction/Adduction
Hip Abduction
Tensor fascia lata, *Sartorius, Gluteus maximus, Gluteus medius
• All of the muscles are located towards the lateral portion of the thigh. When they contract, they pull the thigh away from the midline of the body.

*Sartorius
Sartorius is not located entirely on the lateral portion of the thigh. Because it crosses, laterally to medially, the anterior portion of the thigh, contracting the sartorius results in multiple movements. It would cause flexion, abduction, & lateral rotation of the hip, along with knee flexion. Sartorius originates laterally on the ilium and inserts medially on the tibia. Shortening sartorius would cause the tibia to move closer to the ilium, resulting in hip and knee flexion. It would also pull the tibia medially, causing lateral rotation and abduction of the hip. Looking for gum on the bottom of your shoe would be an example of all the movements of sartorius at once.
Hip Adduction
Adductor longus, Gracilis, Adductor magnus
• All of the muscles are located towards the medial portion of the thigh. When they contract, they pull the thigh towards the middle of the body.
– During this motion the lateral muscles are relaxed and returning to their normal positions.

In this activity, you will again match the muscle to its movement.
