3
In relation to the midtarsal joint: what two muscles produce inversion with tibial and deep fibular nerve?
Tibialis anterior and posterior

Fibularis muscles
5
What foot joint is between the cuneiforms/cuboid proximally and the metatarsals?
Tarsometatarsal
6
What synovial joint of the foot allows flexion, extension, abduction, adduction and circumduction of the digits?
MTP
7
What joint of the foot allows flexion and extension of the toes?
Interphalangeal
8
What structures of the foot provide shock absorption, push off spring in function and increased weight bearing capacity by weight distribution across the whole foot?
Arches of foot
9
What two structures support the arches of the foot?
Plantar aponeurosis
Plantar ligaments
10
What is the thickened central area of the plantar fascia, the deep fascia of the sole of the foot?
Plantar aponeurosis
11
What arch is composed of bones of the medial aspect of the foot (calcaneus, talus, navicular, 3 cuniforms and metatarsals 1-3)?
Medial longitudinal arch
12
What is the medial longitudinal arch supported by?
Flexor hallucis longus, attachments of tibialis anterior and fibularis longus
13
Where does tibialis anterior attach to?
Junction between medial cuniform and base of 1st metatarsal
14
Where does the fibularis longus tendon attach to?
Medial cuniform and base of 1st metatarsal
15
What arch is formed by calcaneous, cuboid, metatarsals 4&5 and is usually weight bearing on standing?
Lateral longitudinal arch
16
What arch consists of cuboid, cuniforms and bases of all 5 metatarsals - also supported by fibularis longus and TA?
Transverse arch
17
What intrinsic muscles of foot produce flexion of toes?
Sole muscles
18
What intrinsic muscles of foot produce abduction.adduction of the toes?
Interossei
19
What is the dorsalis pedis artery a branch of and what does it branch to give?
Branch of anterior tibial artery
Branches to give arcuate artery on dorsum of foot
20
What are the medial and lateral plantar arteries branches of and what do they both contribute to?
Posterior tibial artery
Deep plantar arch
21
Where do metatarsal arteries come from?
Deep plantar arch and arcuate artery
22
What does the dorsal venous arch give rise to?
Great (medially) and small (laterally) saphenous veins
23
What do deep veins of the foot drain into?
Anterior and posterior tibial and fibular veins
24
What nerve supplies motor to the sole muscles?
Tibial
25
What nerve supplies motor to the muscles of dorsum?
Deep fibular
26
In relation to the sensory nerve supply of foot on dorsum: what supplies the first interdigital cleft?
