Which nerve supplies the anterior compartment of the thigh?

Femoral nerve

5

Which nerve supplies the medial compartment of the thigh?

Obturator nerve (L2-L4)
Except hamstring part of adductor magnus- this is tibial nerve

6

Which nerve supplies the posterior compartment of the thigh?

Sciatic nerve
All tibial part except:
Except short head of biceps femoris (common fibular part of sciatic nerve)

7

What is the origin of biceps femoris (long head), semitendinosus and semimembrenosus?

Ischial tuberosity

8

Where does the biceps femoris (long and short head) insert?

Head of fibula

What is the role of muscles in the medial compartment of the thigh?

Adduct thigh
Also flexes thigh and medially rotates

14

What is the role of muscles in the posterior compartment of the thigh?

Flexion at knee

15

Where do gastrocnemius, plantaris and soleus insert?

Calcaneal tendon

16

What is the origin of each gastrocnemius head?

Medial head: Medial condyle of femur

What is the origin and insertion of obturator externus?

Obturator foreamen to greater trochanter (femur)

25

What is the origin and insertion of semitendinosus?

Ischial tuberosity to medial surface of tibia

26

What is the origin and insertion of semimembrinosus?

Ischial tuberosity to medial tibial condyle

27

What is the origin and insertion of popliteus?

Post surface tibia to lateral femur condyle

28
