Condyle

Explanation:

The condyle is one of the outgrowth or projections present at the surface of the bone. The condyle is large and round in shape. It has a smooth articular surface and serves in joints formation. The condyle is present at the end of one bone and joins it with other bones.  

Example: occipital condyles of occipital bone serve in joint formation with the first vertebra of the vertebral column.
