40
Joints of the ankle
1 +2 ankle mortise - prox tib/fib - distal tib/fib 3. talocrural
41
prox tib/fib jt type
plane jt
42
prox tib/fib FN
fibular rotation | up + down hiding
43
distal tib/fib jt type
syndesmois jt | which means fibrous
44
distal tib/fib ligaments
ant tib/fib post tib/fib interosseous --> STRONGEST... in fact so strong that tibia or fibula will break instead of ligament
45

1 medial collateral | 3 lateral collateral
47
what are the parts of the medial collateral
3 parts tibionavicular tibiocalcaneal ant/post tibiotalar
48
what part of calcaneus does tibiocalcaneal go to
susentaculum tali
49
lateral collateral ligaments
ant/post talofibular | calcaneofibular
50
FN of medial collaterals
resist eversion
51
FN of lateral collaterals
resist inversion
52
most common damage is in (a) in (b) collateral ligaments
(a) anterior talofibular (b) lateral collateral ligaments sprained ankle
53
FN of medial + lateral collateral ligs
dorsiflexion | plantarflexion
54
Which vein travels with the saphenous nerve
great saphenous vein
55
where does the great saphenous vein end

68
Function of the plantar aponeurosis
protect sole of the foot (a, v, n) provide support for the longitudinal arches make foot rigid
69
other word for plantar aponeurosis
plantaris longus
70
