Which ligament is described as the ligament on the sole between the heelbone and navicular bone?

• A. Plantar calcaneonavicular ligament
• B. Side branch ligaments between hand bones and fingerbones
• C. Costoclavicular ligament
• D. Round surface for ligament between coracoid process and collarbone

Answer: (A)

The ligaments that connect the heel bone to the navicular bone on the sole are the plantar calcaneonavicular ligaments, also known as the spring ligament. It extends from the sustentaculum tali of the calcaneus to the navicular bone on the plantar side of the foot. Its main role is to support the medial longitudinal arch and act like a spring during weight bearing, helping to maintain proper foot height and stability as you step.

The other options describe ligaments located in different regions (between hand bones and fingers, between the ribs and clavicle, or between the coracoid process and the clavicle), so they don’t match the described location between the heelbone and navicular bone.
