The LONGEST bone in the human body

The human body is made up of 206 bones, which come in a variety of shapes and sizes. From the short, irregular, flat bones of the skull to the long, narrow bones of the extremities, they all have a characteristic shape depending on their function and where they are found.

In this lesson from a TEACHER we will discover What is the longest bone in the human body and because. In addition, we will present you with a list of the 10 longest bones in the body. If you want to know more about the long bones of the human body, read on!

The longest bone in the human body is the bone found in the thigh: the femur. East leg bone it articulates at one end with the coccyx and at the other with the tibia and fibula. As we will see below, its length varies, but it is usually found around 50 centimeters.

Within the musculoskeletal system, the femur has the function of inserting very robust muscles. In fact, a total of 22 individual muscles originate from or insert into the femur, one of the most important being the thigh muscle: the quadriceps femoris. The

quadriceps femoris It is the most voluminous muscle in the entire human body since it is responsible for supporting the entire weight of the human body and allows us to walk, walk, sit and run.

The femur is a long, strong bone that, normally corresponds to more than 25% of the body's height, although its length depends on sex and ethnic origin. That is why these data are of great relevance in anthropology when studying a body; the length of the bone and the data on sex and origin are used to find out the height that, with great probability, the human being could have been when he was alive. When carrying out these studies, it is of great importance to take into account the variation in height within the same population, with age and even the possibility that the individual could have suffered a disease that affected the growth or deterioration of the bones (osteoporosis).

In the human body, in addition to the femur, we can find many long bones but what are the 10 longer bonesof the human body? Here is a list of the longest ones, ordered from longest to shortest:

1. The femur. As we have already mentioned above, it represents 25% of the height of the human body, that is, it can be between 40 and 50 cm in adult individuals of normal size.
2. The tibia. The tibia is the main and anterior bone of the leg. It articulates with the femur, fibula and talus and is usually around 40 centimeters long.
3. Fibula. The other bone that makes up the leg. It is located behind the tibia and is thinner than it. Due to its position and insertion, it is somewhat smaller than the tibia, but still measures around 40 centimeters.
4. Humerus. The humerus is about 36 cm long, although like the other bones on this list, its length varies greatly with the height of the individual. This bone is found in the arm and articulates at one end with the scapula and at the other with the ulna and radius.
5. The ulna. The ulna is considerably smaller than the bones seen so far as it is about 28 centimeters long. It is the thick and long bone that forms the inner part of the forearm.
6. The radio. The radius is the bone next to the ulna, which forms the outer part of the forearm. It is about 26 centimeters in length.
7. The seventh rib. The seventh rib is the last true rib and the false ribs are attached to it by means of cartilaginous tissue. It is 24 cm in length and is the longest rib in the human body.
8. The eighth rib. The eighth rib or false first rib is about 23 cm.
9. The ilium. The ilium is 18.50 cm long. It's a flat bone, shaped like a two-bladed helix. This bone joins the ilium, ischium and pubic bones and is located on the sides of the sacrum where it forms the pelvis.
10. Sternum. The sternum is about 10 cm long. It is a flat bone located in the center of the chest. It is responsible for joining the ribs in the rib cage, allowing the rib cage to have enough elasticity so that we can breathe.
