How does backbone differ from thigh bone?
Answers
Answer:
The head of the humerus is almost hemispherical, while that of the femur forms about two-thirds of a sphere. There is a strong ligament passing from the head of the femur to further strengthen and ensure its position in the acetabulum
Answer:
Backbone, or main chain, is the general term used to describe the connecting chain in polymers. Different kinds of polymers have different chemical backbones. For example, in proteins the backbone is a polypeptide chain, but nucleic acids have a sugar phosphate backbone.
The femur, or thighbone, is the longest, heaviest, and strongest bone in the body. The femur and pelvis form the hip joint at the proximal end. At the distal end, the femur, tibia, and patella form the knee joint. The patella, or kneecap, is a triangular bone that lies anterior to the knee joint.
