25
Q

FDL insertion?

A

divides into 4 tendons deep tin the sole of the foot to insert on the plantar surfaces of the distal phalanges of toes 2-5; note that each tendon passes through the split tendon of the flexor digitorum brevis

26
Q

FDL innervation?

A

Tibial n(S2-S3)

27
Q

FDL action?

A

Flexes toes 2-5 and assists in plantar flexion

28
Q

A

deep posterior compartment middle 1/3 of the shaft of the fibula

29
Q

FHL insertion?

A

plantar surface of the the distal phalanx of the hallux

30
Q

FHL innervation?

A

Tibial n(S2-S3)

31
Q

FHL action?

A

Flexes hallux, assists ankle plantar flexion and assists inversion

32
Q

Tibialis posterior origin?

A

posterior side of the proximal lateral shaft of the tibia, the proximal medial shaft of the fibula

33
Q

Tibialis posterior insertion?

A

8 insertions= Primarily navicular and 1st cuneiform, tendonous expansions of 2nd and 3rd cuneiforms, 2nd, 3rd, and 4th metatarsal bases and cuboid

34
Q

Tibialis posterior innervation?

A

Tibial n(L4-S1)

35
Q

Tibialis posterior action?

A

inversion and adduction of the foot and assists in plantar flexion

36
Q

Gastrocnemius origin?

A

posterior aspect of the femur. superior surfaces of the medial and lateral condyles

37
Q

Gastroc insertion?

A

unites with the soleus to form the tendo-calcaneus(Achilles’ tendon) to insert on the tuberosity of the calcaneus

38
Q

Gastroc innervation?

A

Tibial n(L5-S2;primarily L5-S1)

39
Q

Gastroc action?

A

Plantar flexors at the ankle; assists the hamstrings and popliteus in flexing at the knee and assists the hamstrings at the knee during terminal extension in a closed kinetic chain

40
Q

Soleus origin?

A

Head, neck, and proximal 1/3 of the fibula; and from the posteromedial aspect of the shaft along the popliteal/soleal line

41
Q

Soleus insertion?

A

unites with the gastroc to form the calcaneal tendon

42
Q

Innervation of the soleus?

A

Tibial n(L5-S2)

43
Q

Action of the soleus?

A

Plantar flexion of the foot

44
Q

Popliteus origin?

A

lateral aspect of the lateral femoral condyle

45
Q

Popliteus insertion?

A

posterior aspect of the proximal tibia above the popliteal/soleal line

46
Q

Popliteus innervation?

A

Tibial n(L4-S1)

47
Q

Popliteus action?

A

Internally rotates tibia in an open kinetic chain and externally rotates the femur when the tibia is fixed(closed kinetic chain) and assists knee flexion; it functions primarily as a knee stabilizer

48
Q

Semitendinosus origin?

A

ischial tuberosity

49
Q

Semitendinosus insertion?

A

shaft of the tibia just inferior to the medial condyle as the posterior portion of the pes anserinus

50
Q

Semitendinosus innervation?

A

tibial division of the sciatic nerve (L5-S2; primarily L5)

51
Q

Semitendinosus action?

A

Primarily knee flexion and when the knee is flexed it internally rotates the tibia; also assists extension and internal rotation at the hip

52
Q

Semimembranosus origin?

A

ischial tuberosity

53
Q

Semimembranosus insertion?

A

posterior aspect of the medial tibial condyle

54
Q

Semimembranosus innervation?

A

tibial division of the sciatic nerve(L5-S2; primarily L5)

55
Q

Semimembranosus action?

A

Same as semitendinosus

56
Q

Biceps femoris origin?

A

2 heads? Long head- ischial tuberosity

Short head- distal 1/2 of the lateral lip of the linea aspera and lateral supracondylar line of the femur

57
Q

Biceps femoris insertion?

A

fibular head with slips to the lateral tibial condyle and fibular collateral ligament

58
Q

Biceps femoris innervation?

A

sciatic-tibial division to the long head and peroneal/fiular division to the short head (L5-S2; primarily S10)

59
Q

Biceps femoris action?

A

Flexion at the knee and when the knee is flexed it externally rotates the leg; the long head also assists extension and external rotation at the hip
