1

What bones form the ankle joint? (3)

-Tibia
-Fibula
-Talus

2

What are the tibia and fibula held together by distally?

Tibiofibular ligaments.

3

What is the socket formed by the distal tibia and fibula called?

Mortise.

4

What are the bones of the foot?

-Talus
-Calcaneus (post)
-Navicular (med)
-Cuboid (lat)
-3 Cuneiforms (med)
-5 Metatarsals
-14 phalanges (2 on great toe, 3 on other toes)

5

What are the small bones/outgrowths on the distal end of metatarsal 1?

Sesamoid bones.

6

What type of joint is the ankle joint?

Synovial hinge joint.

7

What movements are possible at the ankle?

-Dorsiflexion, 45* (ant compartment)
-Plantarflexion, 20* (post compartment)
-Inversion, 30*
-Eversion, 20*

8

What ligaments strengthen the ankle posteriorly? (2)

-Posterior tibiofibular ligament
-Posterior talofibular ligament
(-Calcaneal tendon)

9

What ligaments strengthen the ankle medially? (2)

-Deltoid ligament (post tinulotalar & tibulocalcaneal)
-Plantar calcaneonavicular ligament

10

What ligament strengthens the ankle medially/posteriorly?

Calcaneofibular ligament.

11

What are the 2 intertarsal joints?

-Subtalar joint
-Transverse talar joint

12

What is the subtarsal joint formed by?

Talus and calcaneus bones.

13

What movements are possible are the subtarsal joint?

-Inversion (tibialis anterior and posterior)
-Eversion (fibularis longus and brevis)

14

What is the transverse talar joint formed by?

2 articulations:
-calcaneus and cuboid bones
-navicular and talus bones

15

How many arches are there in the foot?

Three.
-1 transverse, 2 longitudinal

16

What supports the longitudinal arches in the foot?

PASSIVE - plantar aponeurosis, short/long plantar ligaments, plantar calcaneal ligament
DYNAMIC - flexor hallucis longus, fibularis longus, intrinsic plantar muscles

17

What supports the transverse arch in the foot?

PASSIVE - wedge shaped cuneiform
DYNAMIC - fibularis longus, tibialis posterior

18

What is pes planus?

Flat foot.
-due to lowered/flattened longitudinal arch

19

What usually causes pes planus?

Loose/degenerating ligaments.

20

Which bone is often displaced with pes planus?

Talus.
-displaced inf/med

21

What are the intrinsic extensor muscles on the dorsum of the foot? (2)

-Extensor halucis brevis
-Extensor digitorum brevis

22

What artery is located on the dorsum of the foot?

Dorsalis pedis artery.

23

Which nerves supply the dorsal aspect of the foot? (2)

-Superficial fibular nerve (L4-S1)
-Deep fibular nerve (L4, L5)

24

What is the motor innervation of the superficial fibular nerve?

-Lateral compartment of the leg

25

What is the sensory innervation of the superficial fibular nerve?

-Most of skin over dorsum of foot (apart from webbing between toes 1 and 2)
-Ant/lat distal 1/3 of leg

26

What is the motor innervation of the deep fibular nerve?

-Anterior compartment of the leg
-Intrinsic extensor muscles of the foot (EDB, EHB)

27

What is the sensory innervation of the deep fibular nerve?

Triangular region between 1st and 2nd toes.

28

Which nerves supply the skin of dorsum of the foot ? (4)

SUPERFICIAL FIBULAR - most of dorsum of foot
DEEP FIBULAR - region between 1st and 2nd toes
SURAL - lateral leg/foot/little toe, lateral malleolus
SAPHENOUS - ant/med leg, medial malleolus

29

Where are the majority of the intrinsic muscles of the foot located?

In the plantar aspect.
-sole of foot

30

How many layers is the plantar aspect of the foot arranged into?

4 layers of muscles.
