Answer 2

(D) Sartorius​

(D) Sartorius ​is a two Joint muscle.

• A long, narrow muscle that passes obliquely from the hip bone to the inside of the leg just below the knee on the front of each thigh.
• The sartorius has a special role because it may act as a knee and hip flexor at the same time.
• The anterior superior iliac spine is where the sartorius originates, along with the tensor fascia lata. It works at the hip to externally rotate as well as flex the hip.
• It twists the thigh laterally, flexes the hip, and weakly abducts at the hip.
• It has the ability to flex the knee, which rotates the leg medially as well.
