Final answer:
The calcaneus is the bone in the heel of the foot, part of the tarsal bones, and it transfers body weight from the tibia to the ground. (option 3)
Step-by-step explanation:
The bone you can feel in the heel of your foot is called the calcaneus. The calcaneus is a large and robust bone that forms the foundation of the hindfoot. Positioned at the back of the foot, it plays a crucial role in weight-bearing and absorbing shock during activities like walking and running. The calcaneus is integral to the structure of the foot, contributing to the formation of the subtalar joint, which is essential for proper foot movement and stability.
Palpating the calcaneus in the heel region is common due to its surface prominence. This bone serves as a point of attachment for the Achilles tendon, a powerful tendon that connects the calf muscles to the back of the heel. The calcaneus, along with other tarsal bones, contributes to the overall architecture of the foot, enabling intricate movements and providing support for the body's weight. Understanding the specific bones of the foot, such as the calcaneus, enhances our appreciation of human anatomy and aids in diagnosing and treating conditions related to the skeletal system.
