Top 10 Longest Bones in the Human Body, we are going to learn about the Longest bone in the human body. Everyone would have the curiosity to know about the Longest bone in the human body and its function.
Two hundred and six is the total number of bones in the human body. We have 206 unique parts that make up our skeleton and they are inherently different from each other.
Bones have many functions in the human body and they are the one to support the body structurally. It also protects our vital organs and allows us to move. There are many functions the bone may take place.
But a few particular bones have a special and particular type of function. Here in this article, we will know about the longest bones in the human body and their function. They are:
List of Longest Bones in the human body:
1. The femur (Thighbone):
Femur bone also called thigh bone is the longest bone in the human body with 19.9 inches which makes it stand in the number one place. Out of the 206 bone, the Femur is the longest and strongest bone in the Human body.
The two Femur bones serve as pillars in our leg that helps us to walk, run, jump, and all other kinds of movements we make in our leg.
The femur is located, as the common term for it suggests, in the thigh or upper portion of the leg and it runs from the hip to the knee.
The proximal end of the bone, the part that is located closest to the hip, has the femoral head that helps to create the joint within the hip. The distal end of the femur is located closest to the knee.
2. Tibia (shin bone):
Tibia also is known as shin bone is the 2nd longest bone in the human body with 16.9 inches. It forms the knee joint with the femur and the ankle joint with the fibula and tarsus.
The tibia is located in the lower leg medial to the fibula, distal to the femur and proximal to the talus of the foot. In humans, the tibia forms the lower half of the knee joint above and the inner protuberance of the ankle below.
It is widest at its proximal end near the femur, where it forms the distal end of the knee joint before tapering along its length to a much narrower bone at the ankle joint.

3. Fibula (lower leg):
The fibula is the 3rd longest bone in the human body with 15.9 inches. The fibula is the long, thin and lateral bone of the lower leg. It runs parallel to the tibia, or shin bone, and plays a significant role in stabilizing the ankle and supporting the muscles of the lower leg.
Compared to the tibia, the fibula is about the same length but is considerably thinner. The difference in thickness corresponds to the varying roles of the two bones; the tibia bears the body’s weight from the knees to the ankles, while the fibula merely functions as a support for the tibia.
4. Humerus (upper arm):
The Humerus is the 4th longest bone in the human body with 14.4 inches. The humerus is the largest bone in the entire upper extremity. The top of the humerus joins with an area called the glenoid fossa on the scapula or shoulder blade.
The bottom of the humerus touches the top of the radius and ulna which joins the upper arm with the lower arm. The meeting of these bones allows for the wide range of motion which is possible at the shoulder joint, along with movement at the elbow.
5. Ulna (inner lower arm):
The Ulna is the 5th longest bone in the human body with 11.1 inches. The ulna is located on the opposite side of the forearm from the thumb. It joins with the humerus on its larger end to make the elbow joint and joins with the carpal bones of the hand at its smaller end.
Together with the radius, the ulna enables the wrist joint to rotate. Ulna fractures cause severe pain, difficulty in moving the joint affected, and even deformity of the arm if the fracture is compound.
6. Radius (outer lower arm):
The radius bone is the 6th longest bone in the human body with 10.4 inches. It is located on the lateral side of the forearm parallel to the ulna (in anatomical position with arms hanging at the sides of the body, palms facing forward) between the thumb and the elbow.
The radius and ulna pivot around one another to allow rotation of the wrist. Together, along with the humerus, they create the elbow joint. The radius provides bodyweight support when the arms are used during crawling and lifting the weight of the body, such as during pushups.
7. 7th rib:
The 7th rib is the 7th longest bone in the human body with 9.5 inches. This is one of the human bones forming the human rib cage. The ribs are the long curved bones which form the rib cage, part of the axial skeleton.
The seventh rib is primarily associated with the liver and stomach. A lesion of the left seventh rib is primarily associated with the stomach while the liver will be affected by the rib on the associated side.
8. 8th rib:
The 8th rib is the 8th longest bone in the human body with 9.1 inches. This is also one of the human bones forming the human rib cage.
Ribs 8 are attached indirectly to the sternum. For these ribs, the costal cartilage of each attaches to the cartilage of the next higher rib. The last false ribs (11–12) are also called floating (vertebral) ribs because these ribs do not attach to the sternum at all.
9. Innominate bone (hipbone):
The Innominate bone is also known as the hip bone is the 9th longest bone in the human body with 7.3 inches.
Innominate bone are the fused bones of the pelvis either side of the sacrum. The bone comprises the ischium, pubis and ilium which are fused to each other in the acetabulum and are part of the appendicular skeleton.
10. Sternum (Breast bone):
The sternum is also known as breast bone is the 10th longest bone in the human body with 6.7 inches.
It is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury.
These are the top 10 longest bones in the human body. Enjoy reading it..!!
