Subtalar joint

2

What two joints make up the midtarsal joints?

1. Calcaneocuboid
2. Talocalcaneonavicular

3

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

Tibialis anterior and posterior

4

In relation to the midtarsal joint: what muscles produce eversion with fibular nerves?

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

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
