Question

iliopsoas
the iliopsoas (ile - o - soas; the p is silent) is a fused muscle composed of two muscles, the iliacus and the psoas major (figure 6.20c). it runs from the iliac bone and lower (1. ) deep inside the pelvis to insert on the lesser trochanter of the femur. it is a prime mover of hip flexion. it also acts to keep the upper body from falling backward when we are standing erect.
adductor muscles
the muscles of the adductor group form the muscle mass at the (2. ) side of each thigh (figure 6.20c). as their name indicates, they adduct, or press, the thighs together. however, because gravity does most of the work for them, they tend to become flabby very easily. special exercises are usually needed to keep them toned. the adductors have their origin on the (3. ) and insert on the proximal aspect of the femur.

hamstring group
the muscles forming the muscle mass of the posterior thigh are the hamstrings (figure 6.20a). the group consists of three muscles - the biceps femoris, semimembranosus, and semitendinosus - which originate on the ischial (4. ) and run down the thigh to insert on both sides of the proximal tibia. they are prime movers of thigh extension and knee flexion. their name comes from the fact that butchers use their tendons to hang hams (consisting of thigh and hip muscles) for smoking. you can feel these (5. ) at the back of your knee.

Explanation:

1. The iliopsoas runs from the iliac bone and lower vertebrae deep inside the pelvis.
2. Adductor muscles are on the medial side of each thigh.
3. Adductors originate on the pelvis.
4. Hamstring group muscles originate on the ischial tuberosity.
5. You can feel hamstring tendons at the back of the knee.
