What is the meaning of the bone term Trochlea?

Explanation:
Trochlea means a pulley-like structure. The word comes from Latin and describes a shape that acts like a small pulley, guiding movement rather than being a simple flat surface. In bone anatomy, a trochlea is a grooved, pulley-shaped surface that allows smooth, guided motion at a joint. For example, the humeral trochlea fits with the ulna to produce the bending motion of the elbow, using its groove to direct movement much like a pulley directs a rope. So the intended meaning is pulley-like structure. The other options refer to a boat, the moon, or a triangle, which aren’t how the term is used in anatomy.
