Femur Bone Anatomy Quiz

Femur Bone Anatomy

• Head of femur: The rounded uppermost part of the femur that fits into the acetabulum of the pelvis, forming the hip joint.
• Fovea capitis: A small depression located on the head of the femur, serves as an attachment point for the ligamentum teres, which stabilizes the hip joint.
• Neck of femur: The constricted region just below the head; it connects the head to the shaft and is a common site for fractures.
• Greater trochanter: A large protrusion on the lateral side of the femur, serving as an attachment point for muscles of the hip and thigh.
• Lesser trochanter: A smaller projection located on the medial side of the femur, also serving as a muscle attachment site, particularly for the iliopsoas muscle.
• Linea aspera: A prominent ridge along the posterior shaft of the femur that serves as an attachment for several muscles and helps stabilize the bone.
• Patellar surface: The smooth area on the distal end of the femur where it articulates with the patella (kneecap), facilitating knee movement.
• Medial epicondyle of femur: A bony prominence on the inner side of the distal femur, providing attachment for ligaments and muscles.
• Lateral epicondyle of femur: Similar to the medial epicondyle but located on the outer side, also acting as a site for muscle and ligament attachment.
• Gluteal tuberosity: A roughened area on the posterior surface of the femur that serves as an attachment point for the gluteus maximus muscle.
• Medial condyle of femur: The rounded bony end of the femur that articulates with the tibia on the inner side of the knee.
• Lateral condyle of femur: The rounded bony end that articulates with the tibia on the outer side of the knee, facilitating smooth knee joint movement.
• Pectineal line of femur: A faint ridge on the posterior surface of the femur, running from the lesser trochanter to the linea aspera, serving as an attachment for the pectineus muscle.
• Adductor tubercle: A small bony prominence located above the medial condyle, providing attachment for the adductor magnus muscle, important for thigh adduction.
