What is the longest and thickest bone in the human body?

Tibia
Fibula
Femur
Humerus

The correct answer is: Femur

The correct answer, the femur, holds the distinction of being the longest and thickest bone in the human body. It is located in the thigh and plays a crucial role in supporting the weight of the body during various activities such as walking, running, and jumping. The femur extends from the hip joint to the knee joint and is vital for maintaining balance and stability during movement. The femur's structural characteristics contribute significantly to its load-bearing capacity, making it essential for mobility and activities involving the lower limbs. Its length allows for effective leverage in movements involving the hip and knee joints, making it a key element in the overall biomechanics of the human body. Understanding this bone's significance helps emphasize the importance of lower body strength and health in fitness training and rehabilitation practices.
