Which term refers to a large rounded end of a long bone usually set off from the rest of the bone by a neck?

Explanation:
In long bones, the large rounded end that forms a joint surface is called the head. It sits at the end of the bone and is typically set off from the shaft by a narrowed region called the neck. The head, usually capped with articular cartilage, provides the rounded surface that articulates with another bone in a joint (think of the femoral head fitting into the hip socket). Other terms describe bumps or ridges for muscle attachment or slight ridges along the bone (tubercle, tuberosity, line), but they do not denote the large rounded articular end.
