Which of the following best represents the structure of a condyle?

The structure of a condyle is best represented by a large convex surface. In anatomy, a condyle refers to a rounded protrusion at the end of a bone that typically articulates with another bone. The convex surface allows for the smooth movement and proper articulation of joint structures, facilitating motion and absorbing shock at points where bones meet.

In contrast, a shaft with two ends is more representative of long bones, while a small cuboid shape characterizes certain types of bones such as those in the wrist and ankle. An irregular bone shape does not accurately capture the specific characteristics of a condyle, which is defined by its rounded, large convex surface that is essential for joint function.
