When we reach adulthood our body is made up of 206 bones, each one of them fulfils an important function to allow us to perform important tasks such as walking, moving, jumping and even listening, since areas such as the middle ear also have small bundles that transmit the vibration of the sounds guaranteeing our hearing.

And when it comes to limbs such as arms or legs, the presence of skeleton is much more evident, although we do not always know the name of each of its parts. If you wonder what the leg bones are, keep reading, because in this article we clarify it in detail.

What is meant by leg?

Before delving into what the leg bones are, it is important to clarify which area we are referring to exactly, because even if you don’t know, there is a difference between the anatomical concept of the leg and the popular idea of ​​this area.

In anatomy, the leg is the third segment of the lower limbs and goes from the knee to the ankle, that is, it only comprises the area that we colloquially call the calf. Therefore, for experts in anatomy or professionals of science, the thigh area is not included in the leg and therefore neither are the bones that make it up.

In a popular way, we call our entire lower limb leg from thigh to ankle. Taking these two concepts into account, it can be explained why in some places it is explained that the leg is made up of 2 bones and in others it is said that there are 3.

The bones that make up the leg and thigh

At the anatomical level and according to the previous explanation, the leg bones are two:

  • The tibia: it is a long bone whose most distant end is part of the knee joint. It is located next to the fibula and is connected to it through the interosseous membrane of the leg. This important bone helps us support our bone while participating in the proper movement of the body.
  • The fibula: it is also known as the fibula and is located on the outside of our leg. Like the tibia, it helps us to support part of the body’s weight effectively.

For its part, the thigh bone is the femur, which is also the longest and most robust bone in our body. It allows the thigh to be joined with the hip and, thanks to the kneecap, it is also part of the knee joint together with the tibia, so that these three bones are a fundamental part of the movement of our lower extremities and of their correct health and well-being. Remember that from the point of view of anatomy the thigh is not included in the leg, so for many specialists the femur is not between the bones of the leg and the distinction must be made separately.
