What are the structural and functional differences between a tarsal and a metatarsal?

Expert Solution

Step 1: Understanding tarsals

Tarsals are a group of seven small bones that make up the posterior half of the human foot, located between the tibia, fibula, and metatarsals. These bones are essential for maintaining the structure and flexibility of the foot and ankle. The tarsal bones include:

1. Talus: This bone sits on top of the calcaneus and forms the lower part of the ankle joint.

2. Calcaneus: The largest tarsal bone, it forms the heel of the foot and plays a crucial role in weight-bearing and balance.

3. Navicular: Located in front of the talus, this bone helps support the arch of the foot.

4. Cuboid: This bone is positioned on the lateral side of the foot, contributing to the stability of the midfoot.

5. Three Cuneiform Bones: These are the medial, intermediate, and lateral cuneiform bones. They connect the navicular bone to the metatarsal bones and are important for maintaining the arch of the foot.
