Femur

The video tutorial provides a comprehensive overview of the femur, the longest and strongest bone in the human body. It covers the femur's structure, its connections with the pelvis, tibia, and patella, and its role in forming the hip and knee joints. The tutorial details the femur's three anatomical sections: proximal, shaft, and distal, highlighting key features and muscle attachments. It also discusses the clinical significance of the femoral neck and the importance of the femur's ability to withstand pressure from all directions.

What is the primary function of the femur in the human body?

• To protect the internal organs

• To produce red blood cells

• To support the weight of the upper body

• To serve as an attachment for muscles

Which joint is formed by the femoral head and the acetabulum of the pelvis?

• Ankle joint

• Hip joint

• Elbow joint

• Knee joint

What is a potential risk associated with a femoral neck fracture?

• Fracture of the tibia

• Dislocation of the hip joint

• Interruption of blood supply to the femoral shaft

• Loss of muscle function

Which muscle attaches to the pectineal line on the femoral shaft?

• Adductor longus

• Gluteus maximus

• Pectineus

• Biceps femoris

What is the function of the linea aspera on the femoral shaft?

• To connect the femur to the pelvis

• To serve as an attachment point for muscles

• To protect the femoral artery

• To support the knee joint

Which structures form the knee joint?

• Femoral shaft and patella

• Femoral head and acetabulum

• Femoral neck and pelvis

• Femoral condyles and tibia

What covers the condyles of the femur to allow smooth joint movement?

• Muscle tissue

• Hyaline cartilage

• Ligaments

• Bone marrow
