Question

The longest bone of the human skeleton is
(a) Femur
(b) Humerus
(c) Tibia
(d) Radius

Answer 1

Hint: Longer and stronger bones are required at the places where there are more muscles present to provide more surface for attachment and support. It is the solitary bone situated inside the human thigh. It is both the longest and the most grounded bone in the human body, stretching out from the hip to the knee.

Complete answer:
Femur the longest bone in the human body. It is present in the thigh i.e. the upper part of the leg of the body. The thigh bone (Femur) is practically 19.9 inches long and is the longest bone in the human body. It runs starting from the hip to around the knee region. As the longest bone in the human body, it is very much protected in skeletal remaining parts.
-The femur bone is present in the thigh of the body. The femur is also called the thigh bone due to its position.
-It is a long rough cylindrical bone with two spherical heads. The upper end of the femur fixes into the hip sockets of the legs and the lower end attaches with the knee cap along with lower leg bones.
-These bones are the longest and the strongest as they are attached to a lot of muscles of which help in various locomotion activities like walking, running, jumping, swimming, etc.
-Femur bone also supports most of the body weight during standing.

Note:
The humerus is the upper arm of the body. The ulna and radius make up the lower arm bones of the body together. And the tibia is found in the calf of the leg along with a smaller one called the fibula. The femur is one of the most very much portrayed bones of the human skeleton in fields going from clinical life systems to measurable medication.
