Which term describes a bump on the surface of a bone where a tendon attaches?

The term that describes a bump on the surface of a bone where a tendon attaches is "process." In anatomical terminology, a process refers to a projection or outgrowth of tissue from a larger body. This feature serves as an important site for muscle and tendon attachment, providing leverage and support for movement.

In contrast, a facet is typically a smooth flat surface on a bone that allows for articulation with another bone rather than tendon attachment. A neck is a narrower section that connects a head of a bone to the shaft, primarily serving as a structural feature rather than a point of attachment for tendons. The head often refers to the rounded end of a bone that typically fits into a socket to form a joint, rather than a bump where tendons attach.
