What is the origin of the satorius?
What is the anterior superior iliac spine
100
What is the insertion of the satorius?
What is the upper medial surface of body of tibia.
100
What are the actions of the sartorius?
What are: flexes hip and knee, laterally rotates thigh if flexed at hip.
100
Articularis genus: O:____ I:_____ A:_____
What is: Articularis genus: O: femoral surface close to knee, off the deep fibers of the vastus intermedius I: synovial membrane of the knee joint A: pulls the synovial membrane of the knee superior with knee extension, prevents impingement of the synovial membrane between patella and the femur
100
Soleus: O:_____ I:____ A:____
What is: Soleus: O: upper fibula, soleal line of tibia I: calcaneus A: plantarflex the foot
200
What are the origins of the rectus femoris?
What is anterior inferior iliac spine, illium just above the acetabulum
200
What are the insertions of the rectus femoris?
What are: common quadriceps tendon into patella, tibial tuberosity
200
What are the actions of the rectus femoris?
What are: extends knee flexes hip
200
Psoas major: O:____ I:_______ A:_____
What is: Psoas major: O: transverse processes of L1-L5 of spine, vertebral bodies of T12-L4 and the intervening intervertebral discs I: iliopsoas tendon to the lesser trochanter of the femur A: hip flexion, lateral rotation
200
Plantaris: O:____ I:____ A:______
What is: O: above the lateral head of gastrocnemius on femur I: calcaneus, calcaneus tendon A: weakly flexes knee, plantarflex the ankle, stabilize knee when standing (what does this resemble...?) (Gastrocnemeous actions)
300
What are the origins of the vastus lateralis?
What is greater trochanter, linea aspera, lateral intermuscular septum
300
What are the insertions of the vastus lateralis?
What are the common quadriceps tendon into patella, tibial tuberosity
300
What are the actions of the vastus lateralis?
What are: extends knee, can abnormally displace patella
300
Illiacus: O:____ I:____ A:______
What is: Illiacus: O: inner surface of upper iliac fossa I: iliopsoas tendon to the lesser trochanter of the femur A: powerful hip flexion, lateral rotation
300
Popliteus: O:_____ I:______ A:_____
What is: O: lateral femoral condyle, arcuate popliteal ligament, lateral meniscus, knee joint capsue I: posterior tibial surface above the soleal line A: laterally and medially rotates femur/tibia and unlocks knee
400
What is the origin of the vastus intermedius?
What is the femoral shaft.
400
What are the insertions of the vastus intermedius?
What are: common quadriceps tendon into patella and tibial tuberosity
400
What is the action of the vastus intermedius?
What is extends knee.
400
Pectineus: O:___ I:___ A:____
What is: O: pectineal line of the pubis, superior pubic ramus I: the pectineal line of the femur (just below the lesser trochanter on the posterior aspect of the femur) A: flexes hip, adducts thigh, medially rotate thigh
400
Flexor digitorum longus: O:______ I:_______ A:_______
What is: Flexor digitorum longus: O: posterior surface of tibia, crural fascia I: plantar surface of bases of the 2-5th distal phalanges A: primarily flexes 2nd-5th toes, weak plantarflexor, weak inversion and adduction of foot
500

Gastrocnemius: O: _____ I:________ A:________
What is Gastrocnemius: O: just above medial condyle, just above lateral condyle I: calcaneus A: plantarflex the ankle, knee flexion (when not weight bearing), stabilizes ankle and knee when standing
