What is the name of the heel bone in the human body?

The heel bone in the human body is called the calcaneus. It is the largest bone in the foot and forms the foundation of the rear part of the foot. The calcaneus plays a crucial role in weight-bearing and walking, as it provides support for the body when standing and serves as an attachment point for several muscles and ligaments, including the Achilles tendon. This tendon connects the calf muscles to the heel, allowing for fluid movement during activities like walking, running, and jumping. Understanding the anatomy of the foot is essential in contexts like emergency care and orthopedic assessments, as injuries to the heel can significantly impact mobility and overall function. The other options refer to different bones in the lower leg and foot, such as the tibia and fibula, which are the two long bones in the lower leg, and the navicular, which is a bone in the midfoot region.
