Which bony landmark is found on the femur?

The lesser trochanter is indeed a bony landmark found on the femur. It serves as an important site for muscle attachment, specifically for the psoas major and iliacus muscles, which are key players in hip flexion. The presence of the lesser trochanter contributes not only to the anatomy of the femur but also to its functional capabilities in movement, such as walking, running, or climbing.

In contrast, the ASIS (anterior superior iliac spine) and PSIS (posterior superior iliac spine) are bony landmarks located on the pelvis, not the femur. These landmarks are important for understanding pelvic positioning and assessing alignment in various movements, but they are not part of the femur itself. The greater trochanter, while also a bony landmark on the femur, serves different muscle attachments and has a distinct anatomical role compared to the lesser trochanter. Understanding the function and placement of these landmarks aids in comprehending human movement and anatomy in a more comprehensive manner.
