- interphalangeal joints
what kind of joint is the tarsometatarsal joint?
planar joint
what kind of joint is the metatarsophalangeal joint?
condyloid joint
what kind of joint is the interphalangeal joint?
condyloid joint
describe the talus bone
- 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
describe the calcaneus
- heel bone
- articulates with talus to form subtalar joint
- articulates with cuboid & navicular to form transverse tarsal joint
describe the navicular bone
- big protuberance on medial side of foot
- articulates with talus, the 3 cuneiform bones, cuboid, & calcaneus
describe the medial, intermediate, & lateral cuneiform bones
- makes up transverse arch of foot
- articulates with navicular & 1st three metatarsal bones
- articulates with cuboid
what bones do the cuboid bone articulate with?
- lateral cuneiform bone
- navicular bone
- calcaneus
- 4th & 5th metatarsals
