What term describes a large, knoblike process on a bone?

The term that describes a large, knoblike process on a bone is "tuberosity." This term specifically refers to a rounded projection on a bone that serves as an attachment point for muscles or tendons. Tuberosities are typically larger than other similar bone features and can be found on various bones throughout the body. Their structure indicates an area where significant stress or pull from muscles occurs, necessitating a strong attachment point.

The other terms have distinct meanings in anatomy. "Crest" refers to a narrow, ridge-like structure, typically serving as a site for muscle attachment but is not knoblike. "Process" is a more general term that describes any projection or outgrowth from a bone, including various shapes and sizes, but does not specifically denote a knoblike feature. "Trochanter" specifically refers to a large, blunt process found only on the femur, and while it is also a large projection, it has a unique definition and location within the skeletal system that does not encompass all knoblike processes.
