1

What joints are the tibiofibular joints?

proximal = synovial plane joint
distal = fibrous syndesmosis

2

Functions of the interosseous membrane

unites tibia and fibula, forms compartments for muscles, provides attachment for muscles.

3

What movements does the ankle joint allow?

plantarflexion (flexion, pointed toes) and dorsiflexion (extension)

4

What ligament is found medially at the ankle?

medial deltoid ligament
radiates from malleolus to talus, calcaneous and navicular

5

What ligament is found laterally as ankle?

Lateral ligaments- anterior and posterior talofibular and calcaneofibular

6

Which foot joint is ellipsoid?

metartarsophalangeal but limited add/abduction

7

What is the subtalar joint?

talocalcaneal

8

how is inversion and eversion produced?

ankle joint combined with movements of subtalar and midtalar joint motion

9

What is inversion? Useful why?

combined adduction and supination and plantarflexion at ankle
useful for uneven ground

10

What strengthens the intertarsal joints?

dorsal and plantar ligaments

11

What is the calcaneus navicular joint strengthened by?

spring ligament (plantar calcaneonavicular)

12

what tendons do you find on the plantar aspect of the foot?

tibialis posterior and anterior, peroneus longus

13

What joints are the tarsometatarsal joints?

plane synovial

14

What type of joints are the metatarsophalangeal joints? What stabilises them?

synovial ellipsoid
strong collateral ligaments, deep transverse metartarsal ligament, plantar ligaments and extensor tendon fibres

15

Name the 3 arches of the foot?

Medial and lateral longitudinal and transverse arch

16

What bones are involved and what stabilises the medial longitudinal arch?

calcaneus, talus, navicular, cuniforms and medial 3 metartarsals
spring ligament

17

What bones are involved and what stabilises the lateral longitudinal arch?

calcaneus, cuboid, lateral 2 metartarsals
long plantar ligament

18

What bones are involved and what stabilises the transverse arch?

metartarsals
tendons of the fibularis longus and tibialis posterior

19

What do the lubricals and quadratus plantae attach onto?

flexor digitorum longus

20

What muscle in the foot are there 2 names for?

quadratus plantae = flexor accessorius

21

Name the foot extensors

extensor digitorum longus and brevis, extensor hallucis longus

22

What intrinsic muscles move the big toe?

abductor hallucis, flexor hallucis brevis, adductor hallucis

23

What intrinsic muscles move the little toe?

abductor digiti minimi, flexor digiti minimi brevis

24

What is the axis for adduction/abduction of the toes?

the 2nd toe

25

What are the intrinsic foot muscles innervated by?

the tibial nerve via the medial and lateral plantar nerves

26

Name the arteries of the foot

medial and lateral plantar arteries, dorsalis pedis artery, plantar arch
