Q

describe the talus bone

A
  • most superior bone of the foot
  • articulates with tibia & fibula to form talocrural joint
  • articulates with navicular to form transverse tarsal joint
  • most foot motions are related to the talus
17
Q

describe the calcaneus

A
  • heel bone
  • articulates with talus to form subtalar joint
  • articulates with cuboid & navicular to form transverse tarsal joint
18
Q

describe the navicular bone

A
  • big protuberance on medial side of foot

- articulates with talus, the 3 cuneiform bones, cuboid, & calcaneus

19
Q

describe the medial, intermediate, & lateral cuneiform bones

A
  • makes up transverse arch of foot
  • articulates with navicular & 1st three metatarsal bones
  • articulates with cuboid
20
Q

what bones do the cuboid bone articulate with?

A
  • lateral cuneiform bone
  • navicular bone
  • calcaneus
  • 4th & 5th metatarsals
