What are the main functions of the foot?

Supports & propulsion

3

How many large muscles are in the foot?

19

4

Movement of the top of the ankle & foot toward anterior tibia

Dorsiflexion (flexion)

5

Movement of ankle & foot away from tibia

Plantar flexion (extension)

6

Turning ankle & foot outward; abduction, away from midline; weight is on medial edge of foot

Eversion

7

Turning ankle & foot inward; adduction, toward midline; weight is on lateral edge of foot

Inversion

8

Combination of ankle dorsiflexion, subtalar eversion, & forefoot abduction (toe-out)

Pronation

9

Combination of ankle plantar flexion, subtalar inversion, & forefoot adduction (toe-in)

Supination

10

If the foot is too rigid it doesn't __________ adequately

Pronate

11

Difference between walking & running:

Walking= one foot is always in contact with ground
Running= point of time when neither foot is in contact with ground

12

_____ bones in each foot that form arch

26

13

Between the talus & 3 cuniforms

Navicular

14

Between calcaneus and 4th & 5th metatarsals

Cuboid

15

Sesamoid bones increase:

Mechanical advantage

16

Serves as a pulley for posterior tendons to increase mechanical advantage of muscles in performing inversion & eversion actions

Distal malleoli of tibia & fibula

17

High ankle sprain=

Sydesmosis joint sprain

18

What does the high ankle sprain involve?

Anterior inferior tibiofibular ligament

Ankle joint is a _________ joint

hinge

20

Where does inversion & eversion happen?

29

Halluces means:

big toe

30

Origin of the extensor digitorum longus:
