muscles of the anterior compartment of the leg

A

tibialis anterior
extensor digitorum longus
extensor hallucis longus
fibularis tertius

28
Q

muscles of the lateral compartment of the leg

A

fibularis longus and brevis

29
Q

what does the fibularis brevis attatch to

A

the small toe

30
Q

where does the fibularis longus attatch

A

passes under the foot and goes to the big toe

31
Q

what is the lateral compartment supplied by

A

superficial fibular nerve

32
Q

what are the two branches of the common fibular nerve

A

superfiscial fibular nerve

deep fibular nerve

33
Q

what does the superfiscial fibular nerve supply

A

lateral compartment of the leg

34
Q

what does the deep fibular nerve supply

A

anterior compartment of the leg

35
Q

what do the muscles of the lateral compartment do

A

eversion of the foot

36
Q

what are the retinacula

A

thickenings of the deep fascia

37
Q

what are the two extensor retinacula

A

superior and inferior

38
Q

what is the shape of the inferior extensor retinaculum

A

Y shaped

39
Q

what are the two parts of the posterior compartment

A

superfiscial and deep

40
Q

superfiscial posterior compartment of the leg muscles

A

gastrocnemius
soleus
plantaris

41
Q

plantar flexors

A

gastrocnemius and soleus

42
Q

where does the gastrocnemius and soleus converge

A

calcaneal tendon

43
Q

what is the plantaris for

A

proprioception

44
Q

what is the superfiscial posterior compartment supplied by

A

posterior tibial artery

45
Q

what is the superfiscial posterior compartment innervated by

A

tibial nerve

46
Q

deep posterior compartment muscles

A

popliteus
tibialis posterior
flexor digitorum longus
flexor hallucis longus

47
Q

what nerve supplies the deep posterior compartment

A

tibial nerve

48
Q

what artery supplies the deep posterior compartment

A

posterior tibial artery

49
Q

longest vein in the body

A

great saphenous vein

50
Q

what happens if you snap the calcaneal tendon

A

under so much tension you cant get them back together

51
Q

why is the talocrural joint very stable in dorsiflexion

A

the talus is thicker at the back and so it is wedged in place

52
Q

why are you more likely to get an injury in plantar flexion

A

talocrural joint is less stable

53
Q

what is the talocrural joint stabalised by

A

collateral ligaments: fibular collateral ligament and the deltoid collateral ligament

54
Q

at which joint does inversion and eversion happen

A

subtalar joint

55
Q

what type of joint is the subtalar joint

A

ball and socket

56
Q

what ligament supports the talus slotting into the navicular

A

spring ligament

57
Q

pes cavus

A

when the arches of the foot are too big

58
Q

pes planus

A

flat foot

59
Q

hallux valgus

A

big toe deviates inwards

60
Q

what do you get with hallux valgus

A

bonion
