subtalar joint

3
Q

what movement do the tibialis ant and pos cause

A

inversion of the foot

4

calcaneocuboid and talocalcaneonavicular

6
Q

What joint is between the cuneiforms/cuboid proximally and the metatarsals

A

tarsometatarsal joints

7
Q

what are the main movements of the mid tarsal joints

A

inversion (tibialis ant and pos) and eversion (fibularis muscles)

8
Q

what type of joints are the midtarsal joints

A

synovial

9
Q

what type of joints are the MTP

A

synovial

10
Q

what type of joints are the interphalangeal joints

A

synovial hinge joints - flexion and extension of the toes

11
Q

what is the function of the arches of the foot

A

shock absorption, push off spring function, inc weight bearing capacity by weight redistribution across the whole foot

12
Q

what are the arches supported by

A

plantar aponeurosis and plantar ligaments

13
Q

what also protects against puncture wounds

A

plantar aponeurosis

14
Q

what is the plantar aponeurosis

A

thickened central area of plantar fascia - deep fascia of the sole of the foot

15
Q

what is the medial longitudinal arch formed from

A

calcaneus, talus, navicular, 3 cuneiforms and 1-3 metatarsals

16
Q

what is the medial longitudinal arch supported by

A

flexor hallicus longus

attachment of tibials ant

attachment of fibularis longus

17
Q

what is the lateral longitudinal arch formed by

A

calcaneus, cuboid and metatarsals 4 and 5

18
Q

what arch is usually weight bearing on standing

A

lateral longitdunal arch

19
Q

what plane of the foot is the transverse arch located in

A

coronal

20
Q

what is the transverse arch formed by

A

cuboid, cuneirforms and the bases of all 5 metatarsals

21
Q

what is the transverse arched supported b

A

fibularis longus and tibialis posterior

22
Q

what action do the sole muscles produce

A

flexion of the toes

23
Q

what action do the interosse muscles produce

A

abduction/adduction of the toes

24
Q

what is the dorsalis pedis artery a branch of

A

anterior tibial artery

25
Q

where is the pulse of the dorsalis pedis artery taken

A

lateral to extensor hallicus longus tendon

26
Q

what does the dorsalis pedis artery branch to

A

arcuate artery on the dorsum of the foot

27
Q

what do the medial and lateral plantar arteries branch from

A

pos tibial artery

28
Q

what arch do the med and lat plantar arteries contribute to

A

deep plantar arch

29
Q

what arises from the deep plantar arch (artery)

A

metatarsal arteries which branch into digital arteries

30
Q

how many digital arteries per toe

A

4

31
Q

superficial veins: what does the dorsal venous arch give rise to

A

small and great saphenous vein

32
Q

describe th deep veins of the foot

A

follow arteries

drain into ant and pos tibial and fibular veins - join to form the popliteal vein

33
Q

describe the motor supply to the foot

A

tibial nerve to the muscles of the sole of the foot

deep fibular nerve to the muscles of the dorsum

34
Q

sensory nerve supply to the dorsum of the foot

A

mainly superficial fibular with deep fibular nerve supplying the first interdigital cleft

sural nerve supplying the proximal lateral border

saphenous nerve supplying the medial border

35
Q

what is the sural nerve formed from

A

a sensory nerve formed from tibial and common fibular nerves

36
Q

sensory nerve supply to the plantar surface of the foot

A

Mainly tibial nerve to the heel and majority of sole (medial and lateral planter nerves)

sural nerve supplying the proximal lateral border

saphenous nerve supplying the proximal medial border (borders as for the dorsum)

37
Q

describe the lymphatic drainage of the foot

A

lymphatic vessels accompany the great and small saphenous veins
