The heel bone is called the calcaneus.
The Calcaneus: Anatomy and Function
The calcaneus is a crucial bone in the foot's structure, playing a vital role in locomotion and weight-bearing. Let's delve into its specifics:
- Location: The calcaneus is the largest of the tarsal bones, located in the hindfoot, specifically below the bones that form the ankle joint.
- Size: As the largest tarsal bone, it is quite robust, designed to withstand the considerable forces of walking, running, and jumping.
- Function: The calcaneus's primary function is to provide support and leverage for the foot. It acts as the attachment point for the Achilles tendon, allowing for plantar flexion of the foot (pointing the toes down).
- Connection: The calcaneus lies at the back of the foot (hindfoot), specifically below the bones that make up the ankle joint.
Understanding the Tarsal Bones
Here’s a simple table to help understand where the calcaneus fits among the tarsal bones:
Bone Group | Example Bones |
---|---|
Tarsals | Calcaneus, Talus, Navicular, Cuboid, Cuneiforms |
Metatarsals | Bones of the Foot Arch |
Phalanges | Bones of the Toes |
The calcaneus is essential for walking, running, and balancing. Its unique design and position allow for efficient movement and effective shock absorption during physical activities. Understanding its role helps appreciate the complexity of the human foot.
