Answer 2

• Syndesmoid joint
• Tibia/Fibula
• Gliding, Rotation

Question 3

Tarsometatarsal joint

Answer 3

• Synovial plane joint
• 5 metatarsal bones/3 uniforms/cuboid
• Flexion, Extension, Abduction, Adduction, Rotation

Question 4

Metatarsophalangeal joint

Answer 4

• Flexion, Extension, Abduction, Adduction, Circumduction (of toes e.g. spreading), plantar and dorsiflexion

Question 5

Interphalangeal Joints

Answer 5

• Hinge joint
• Joints between phalanges
• Flexion, Extension, and (small amount) abduction and adduction

Question 6

Anterior Talofibular Ligament (ATFL)

Answer 6

• Attaches from anterior lateral malleolus and talus
• Stabilises ankle joint and prevents inward rolling of the foot (excessive)

Question 7

Calcaneofibular Ligament (CFL)

Answer 7

• Lateral malleolus to calcaneus
• Stabilises ankle joint and prevents inversion of the foot (excessive)

Question 8

Posterior Talofibular Ligament (PTFL)

Answer 8

• Lateral malleolus to posterior aspect of talus
• Aligns ankle during movement and prevents movement of talus bone (excessive)

Question 9

Deltoid ligaments

Answer 9

• Medial side of ankle
• Consists of 4 ligaments: Tibionavicular, Tibiocalcaneal, Anterior Tibiotalar, Posterior tibiotalar ligaments
• Provide stability and prevent excessive inversion and eversion
