What is the name of the bony process on the proximal, medial side of the femur?

The lesser trochanter is a bony process located on the proximal, medial side of the femur. It serves as an important attachment point for muscles, particularly the iliopsoas muscle, which is crucial for hip flexion. This structure is smaller than the greater trochanter, which is located laterally and is a site for attachment of other muscles such as the gluteus medius and minimus. The femoral head, also mentioned in the options, refers to the rounded top of the thigh bone that forms the hip joint and is situated superiorly, rather than medially. The ischial tuberosity, located on the pelvis, provides support when sitting but is not associated with the femur. Understanding the anatomy of these structures is crucial for comprehending their functions and relationships in the musculoskeletal system.
