What is the type of muscle adductor magnus?

Adductor Magnus is a broad triangular muscle forming a septum which divides the anterior muscles from the posterior aspect of the thigh. It is the largest muscle in the medial compartment. It lies deep to the adductor brevis and the adductor longus.

What is hamstring part of adductor magnus?

The most medial part of the muscle, the hamstring part, stemming from the ischial tuberosity, forms the thick medial margin of the muscle that descents almost vertically towards the lower end of the thigh.

Does adductor magnus flex the knee?

Since it crosses the joint, it acts on to different parts of the leg; it causes adduction at the thigh and flexion at the knee. It is innervated by the obturator nerve (L2-L4). Adductor Magnus is the largest muscle of the medial compartment, lying posteriorly of the group.

Is adductor inner or outer thigh?
