Question

What two bones does the base of the fifth metatarsal articulate with?

a) The cuboid and navicular bones

b) The talus and calcaneus bones

c) The first and second metatarsal bones

d) The fourth and sixth metatarsal bones

Answer 1

Option A. The base of the fifth metatarsal articulates with the cuboid and the lateral cuneiform bones of the foot.

Step-by-step explanation:

The base of the fifth metatarsal articulates with two bones of the foot: the cuboid and the lateral cuneiform bones. Specifically, the fifth metatarsal's proximal part connects to the cuboid, which is one of the tarsal bones located laterally in the foot, and it also articulates with the lateral cuneiform, which is part of the intermediate series of the tarsal bones.

The cuboid bone is located anterior to the calcaneus and has a deep groove for muscle tendon passage. It also articulates with the lateral side of the navicular and lateral cuneiform bones. Therefore, the correct answer to the question, 'What two bones does the base of the fifth metatarsal articulate with?' is a) The cuboid and navicular bones.

The metatarsal bones are the five bones in the anterior half of the foot. The base of each metatarsal bone articulates with either the cuboid or cuneiform bones. In the case of the fifth metatarsal, it articulates with the cuboid and navicular bones.
