What are the four projections on bone?
Explanation
The four projections on bone are the head, process, crest, and spine. The head refers to the rounded end of a bone that fits into a joint. A process is a bony prominence or projection, such as a tubercle or tuberosity. A crest is a sharp ridge or border, often found on the top of a bone. A spine is a sharp, slender projection of a bone, often serving as an attachment point for muscles or ligaments. These four projections play important roles in the structure and function of bones.Rate this question:
