Arches of The Foot - Coggle Diagram

- - - - Talus
        
        Recieves the weight of the body from the Tibia
        
        Has no muscular attachments
      - Calcaneus
        
        Largest and strongest bone in the foot
        
        Transmits body weight from Talus to the ground
      - Cuboid
        
        Most lateral bone in the distal row of tarsals
        
        Has a groove for the fibularis longus muscle
      - Navicular
        
        Forms the Longitudinal arch of the foot
        
        Site for tendon attachment
      - 1st, 2nd, 3rd cuneiform
        
        Articulates with the navicular posteriorly and metatarsals anteriorly
  - - - Proximally: Base
      - Midpoint: Shaft
      - Distal: Head
    - - 1st Metatarsal (Great Toe)
        
        Has Sesamoid bones on the plantar surface
      - 2nd Metatarsal
      - 3rd Metatarsal
      - 4th Metatarsal
      - 5th Metatarsal (Smallest toe)
        
        Tuberosity of the 5th projects laterally over the Cuboid
        
        This projection provides an attachment site for Fibularis Brevis
  - - - 2 Phalanges (Proximal & Distal)
    - - 3 Phalanges (Proximal, Middle, & Distal)
- - - - Characteristics
        
        Higher & more important compared to the lateral arch
        
        Elasticity, due to height & number of small joints
      - Composed of
        
        Calcaneus
        
        Talus
        
        Talar Head is the keystone of the medial arch
        
        Navicular
        
        3 Cuneiforms
        
        3 Metatarsals
      - Supporting Muscles
        
        Tibialis Anterior Tendon
        
        Tibialis Posterior Tendon
        
        Fibularis Longus Tendon
        
        Flexor Digitorum Longus
        
        Flexor Hallucis Longus
        
        Intrinsic foot musculature
    - - Structure:
        
        Much flatter shape
        
        Rest on the ground during standing
      - Composed of:
        
        Calcaneus
        
        Cuboid
        
        Lateral two Metatarsals
      - Supporting Muscles
        
        Fibularis Longus
        
        Flexor Digitorum Longus
        
        Intrinsic Foot musculature
    - - Primary load bearing and shock distributor
  - - - Coronal plane of the foot
    - - Cuboid
      - 3 Cuneiforms
      - Bases of each metatarsal
    - - Fibularis longus
      - Tibialis Posterior
      - Transverse head of Adductor Hallucis
    - - Provide transverse stability, allowing weight to be shared across all 5 Metatarsals
