Study Notes
Femur Overview
- The femur is the longest, strongest, and heaviest bone in the human body.
Femur Anatomy
- The head of the femur articulates at the acetabulum of the pelvis.
- The greater trochanter of the femur is the site of attachment for the gluteus medius, gluteus minimus, and iliotibial tract muscles.
- The neck of the femur is a narrow, cone-shaped region that connects the head to the shaft, providing a wide range of motion.
Femur Structure
- The proximal aspect of the femur has three bony processes: the greater trochanter, lesser trochanter, and head.
- The neck of the femur projects at an angle of approximately 125° to the shaft.
Muscular Attachments
- The gluteus medius, gluteus minimus, and iliotibial tract muscles originate from the greater trochanter of the femur.
- Forceful contraction of the gluteus medius at the greater trochanter can cause the femur to rotate laterally.
Joint Formation
- The head of the femur articulates with the acetabulum of the pelvis to form the hip joint.
