Which structure connects the pelvis to the lower limbs?

The structure that connects the pelvis to the lower limbs is the femur. The femur, also known as the thigh bone, is the longest and strongest bone in the human body. It plays a crucial role in weight-bearing and movement, acting as the primary connection between the hip joint (at the pelvis) and the knee joint (leading to the lower leg).

In adults, the femur articulates with the acetabulum of the pelvis to form the hip joint, which allows for a wide range of motion in the lower limbs. This connection is essential for locomotion, as it facilitates the transfer of forces from the torso to the legs, enabling activities such as walking, running, and jumping.

Understanding the anatomy of the femur and its role in the skeletal system is fundamental in emergency medical care, as any injury to the femur can significantly impact mobility and may require immediate attention.
