Leg

Leg (/lɛɡ/) is a weight-bearing and locomotive anatomical structure, usually having a columnar shape. In the human body, the leg is the lower limb of the body, extending from the hip to the ankle, and including the thigh, the knee, and the cnemis.

Etymology

The word "leg" comes from the Old Norse word "leggr", which means "leg, bone of the arm or leg".

Anatomy of the Leg

The leg contains several distinct regions and is divided into four segments: the thigh, the knee, the lower leg, and the foot. Each of these segments contains specific bones, muscles, nerves, and blood vessels.

  • Thigh: The thigh is the area between the hip and the knee. It contains the femur, the longest bone in the human body.
  • Knee: The knee is a hinge joint that connects the thigh with the lower leg. It is made up of the patella (kneecap), the lower end of the femur, and the upper end of the tibia.
  • Lower leg: The lower leg, also known as the calf, is the area between the knee and the ankle. It contains the tibia and fibula bones.
  • Foot: The foot is the lowermost part of the leg. It is responsible for supporting the body's weight and enabling locomotion.
