Yes, women's elbows are slightly different from men's.
While the basic bone structure is the same, there are subtle differences in the angles and mobility of the elbow joint. Women generally have slightly more flexible elbows than men, allowing for a greater range of motion. This means women's arms can bend a little further away from their bodies compared to men. This difference, along with shoulder differences, contributes to the overall biomechanics of the arm.
It's important to note that these are general trends and not absolute rules. Individual variation exists, and not all women will have more flexible elbows than all men. However, on average, the difference exists.
These variations can be attributed to differences in hormones, muscle mass, and skeletal structure. Further research may reveal additional factors contributing to these differences.
