Q
Soleus
A
O = posterior tibia & fibula I = posterior calcaneus A = ankle plantar flexion N = tibial nerve
1
Q
Gastrocnemius
A
O = medial & lateral condyles of femur I = posterior calcaneus A = knee flexion, ankle plantar flexion N = tibial nerve
2
Q
Plantaris
A
O = posterior lateral condyle of femur I = posterior calcaneus A = very weak assist in knee flexion & ankle plantar flexion N = tibial nerve
3
Q
Tibialis posterior
A
O = interosseous membrane, adjacent tibia and fibula I = navicular and most tarsals and metatarsals A = ankle inversion; assists in plantar flexion N = tibial nerve
4
Q
Flexor hallucis longus
A
O = posterior fibula and interosseous membrane I = distal phalanx of the great toe A = flexes great toe; assists in inversion and plantar flexion N = tibial nerve
5
Q
Popliteus
A
O = Lateral condyle of femur I = posterior surface of medial condyle of tibia A = initiates knee flexion N = tibial nerve
6
Q
Vastus intermedialis
A
O = anterior femur I = tibial tuberosity via patellar tendon A = knee extension N = femoral nerve
7
Q
Vastus medialis
A
O = linea aspera I = tibial tuberosity via patellar tendon A = knee extension N = femoral nerve
8
Q
Vastus lateralis
A
O = linea aspera I = tibial tuberosity via patellar tendon A = knee extension N = femoral nerve
9
Q
Tensor fascia latae
A
O = anterior superior iliac spine (ASIS) I = lateral condyle of tibia A = combined hip flexion & abduction (ABD) N = superior gluteal nerve
10
Q
Gluteus minimus
A
O = lateral ilium I = anterior surface of the greater trochanter A = hip abduction (ABD) & medial rotation N = superior gluteal nerve
11
Q
Gluteus medius
A
O = outer surface of ilium I = lateral surface of greater trochanter A = hip abduction (ABD) N = superior gluteal nerve
12
Q
Biceps femoris
A
O = long head: ischial tuberosity
Short head: lateral lip of linea aspera
I = fibular head
A = long head: hip extension & knee flexion
Short head: knee flexion
N = long head: sciatic nerve
Short head: common peroneal nerve
13
Q
Semitendinosus
A
O = ischial tuberosity I = anteromedial surface of proximal tibia A = hip extension & knee flexion N = sciatic nerve
14
Q
Semimembranosus
A
O = ischial tuberosity I = posterior surface of medial condyle of tibia A = hip extension & knee flexion N = sciatic nerve
