Question

Which of the following bones are the longest in the body?
A) Two fibulas
B) Two femurs
C) Two tibias
D) Two ulnas

Answer 1

Hint: The thigh bone is the longest and the strongest bone in a skeleton. In humans, the thigh bone is longest and they have two legs with two femurs for locomotion.

Step by step answer: There are 206 to 210 bones in an adult human body. Out of which, 60 bones are found in legs. There are 2 femur bones, 2 knee caps or patella, 2 tibia bones, 2 fibula bones and 26 bones per foot (52 bones in the foot). The bone has a head region joined with the acetabulum in the pelvic bone. The other part of the femur joins with the tibia and kneecap or patella. It is the part of the upper leg which is longer than any other bone in the body. It can defend itself with 1800 to 2500 pounds, so it is the strongest. It shows very few chances of fractures in the thigh bone. Still, if any accidents take place, it takes three to 6 months to heal. In some animals, they are not the strongest but they are still present. The femur forms a ball and a socket joint with the hip which is being held in a place by the ligament.
Hence, the correct answer is option B.

Note: Femurs are not only present in the humans, but they are also present in arthropods in legs. When talking about the strongest bone, the jawbone and skull bone is also very strong with the femur.
