Name the two arches of the foot?
Logitudinal and Transverse Arches
Function of arches in feet?
Distribute weight
Act as shock absorbers
Act as spring boards
What is the transverse arch made up of
Tendon of Tibialis Posterior
Tendon of Peroneus (Fibularis) Longus
Adductor Hallucis muscle
Deep transverse metatarsal ligament
The tendon of tibialis posterior and tendon of peroneus (fibularis) Longus make up ?
Tarsal Arch
Adductor Hallucis muscle makes up ?
Metatarsal Arch
Deep Transverse Metatarsal Ligament
Anterior Arch
Bones of Lateral arch?
Calcaneus, cuboid, Metatarsal 4 and 5
What happens to the lateral arch when standing?
It rests on the ground
Bones of medial arch
Calcaneus, Talus, Navicular, 3 cuneiforms, Metatarsals 1-3
Is the medial arch higher or lower than the lateral arch
Higher and more important than lateral arch
Dynamic support of longitudinal arch of foot ?
