Biggest Bone In Body: This Will Leave You Astonished

The thigh bone or the femur is the longest and strongest bone of human anatomy.

It is the only bone in the upper leg located above the tibia and fibula of the lower large. Femurs support the entire weight of the human body.

The human body is made up of 206 distinct bones. These bones are inherently different from each other and many people are curious to know about the interesting facts related to bones. Different bones are responsible for different functions and the hard structure skeleton made up of bones helps in the protection of the vital organs. Out of all these bones in the human skeleton, the longest bone is the thighbone or femur. Apart from the femur, there are many long bones in the human body. The three largest bones after the femur are the tibia or the shin bone, the fibula or the lower leg, and the humerus or the upper arm. The fibula is the third-largest bone. The biggest concentration of bone in the human body is in the hands and feet with a total of 106 bones.

The femurs serve as the pillar bones in the human body as they help us to make all kinds of movements of the legs. It is also the strongest bone of the skeletal system. The femur is the only bone around the thigh area. It is a light-weighted hollow bone but is as strong as concrete.

Weird Facts About Biggest Bone In Body

The longest bone, the femur is sure an important bone but the bone has some weird facts related to it. Apart from being the longest bone, the femur is also a very important bone in the human body. Even though the tibia is vertically set from the knee joint up to the ankle, the femur is set at a 10-15 degree angle called the Q-angle. The Q-angle is greater in females since males have a narrower pelvis than the females.

Among all the long bones of the leg and arm, the femur is the longest in the skeletal system. The length of a person or any animal varies according to the height of the individual. One fun way to know about the length of your femur is by calculating one-third of your height. This is because the length of the femur is always about a quarter of an individual's height. Therefore, you can easily presume how long their femur is actually.

Now coming to the significant role of the femur, it plays the role of the weight-bearing bone of the human body. The femur along with the tibia teams up with the other bones of the foot to support the weight of the human body. However, the stabilizing leg muscle fibula does not play any role in bearing the weight along with the tibia and femur. Weight-bearing exercises like walking, jogging, and running help in maintaining the health of bones and make bones denser. The medial femoral condyle is responsible for bearing a larger amount of weight as the center of gravity is medial to the knee.

Being a long bone in the human skeleton, the femur is made up of both red and yellow bone marrow. The red bone marrow is composed of hematopoietic tissue. The functional unit of this tissue is stem cells that are responsible for creating new platelets and red blood cells. On the other hand, the yellow bone marrow is mostly made up of fat.

Insightful Facts About Biggest Bone In Body

The biggest bone femur is the only bone located in the upper leg of the human body. The femur's head is attached to the pelvic bone which results in the formation of the hip joint. The lateral end of the femur attaches with the patella or the knee cap and the proximal ends of the tibia. The thick pelvis makes the femora converge more in women.

Femurs are measured to be the longest bone in humans; it is considered to be the largest, as well as, the thickest bone. It is also the strongest bone of the human skeleton. The anatomy of the femur is divided into three parts: the upper portion, the body, and the lower portion. The upper extremity is the shortest, while the lower extremity is taken to be the thickest femoral extremity in the human anatomy. The body of the femur is cylindrical in shape. It is thinner from the centre and broadest and looks somewhat flattened from below. It serves as an attachment point for all the muscles and bones located above the hip and knee.

The femur is also the originating point for some biarticular muscles like plantaris and gastrocnemius muscles. In total, 23 muscles either insert into or originate from this bone. The transitioning area of the femur from the head is quite rough in nature since many muscles attach to the hip bone in this area. The lower extremity consists of two condyles that do not lie parallel to each other. The femur in humans is slightly arched, it is convex in the front and concave behind where the femur is strengthened by a longitudinal ridge. A bony projection called the third trochanter is sometimes observed to be present on the femur near the gluteal tuberosity border.

Interesting Facts About Biggest Bone In Body

The human skeleton has 206 bones out of which the femur is the strongest and the longest bone of the body. The main function of the femur is to bear the weight of the human body and maintain the stability of the gait. However, there are some interesting facts about this bone that you might want to know.

When we say the femur bears the weight of the body, we mean that the entire weight only sits on the two femoral heads of the bones. The femur forms one of the most essential components of the lower kinetic chain. These bones can be divided into three parts: proximal, shaft, and distal. The proximal femur consists of the femoral head, neck, and the two bony protrusions called the greater trochanter and lesser trochanter. The trochanters attach muscles to the bones. The shaft slightly arches in an anterior position and in the distal femur the shaft finally flares into a cone-shaped structure. The base of the distal femur looks cuboidal and is composed of the lateral and medial condyle. The condyles present helps in joining the femur to the bone, tibia. The fibula present in the lower leg is separated from the femur by the patella.

Surprising Facts About Biggest Bone In Body

The femur located between the hip and the knee is not only the largest bone of the human body but there are some surprising facts about the bone. It is the only bone between the hip and the knee. The measurement of the femur bone shows that it makes up one-third of the total height of a person.

The femur plays a big role in helping us to stand, walk, and run. Basically, it allows us to move our legs in whichever way we want and in all directions. It is a highly distinct bone because of its robust nature. The large structure of the bone might suggest that the bone is heavy, however, the opposite is true. The femur is a hollow bone that makes it light weighted. Still, the bone is stronger than concrete and its main function is to bear the weight of the upper human body. Breaking or fracturing the femur takes a lot of force. Intense car accidents and falling from great heights are the two most familiar cases where the femur bone might be fractured. Some common early syndromes of femur fractures are fat embolism, compartment syndrome, and shock.
