Answer 15

condyloid joint

Question 16

describe the talus bone

Answer 16

• 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

Question 17

describe the calcaneus

Answer 17

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

Question 18

describe the navicular bone

Answer 18

• big protuberance on medial side of foot

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

Question 19

describe the medial, intermediate, & lateral cuneiform bones

Answer 19

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

Question 20

what bones do the cuboid bone articulate with?

Answer 20

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