Question

A curved bone is structurally designed to

• A. Accommodate easily in body
• B. Absorb the stress of the body weight at several different points so that the stress is evenly distributed
• C. Provide more area for attachment of muscles
• D. All of the above

Answer 1

Answer: (B)

Absorb the stress of the body weight at several different points so that the stress is evenly distributed

Long bones are longer than they are wide and they are slightly curved for strength.
– A bone that is curved is structurally able to absorb the stress of the body at several points so the stress will be evenly distributed.
– The straight bone would not be able to evenly distribute the weight of the body and the bone would break more easily.
– Long bones are shaped like tubes with rounded ends that are designed to fit into other bones to form joints.
– The ends of long bones are filled with spongy bone; this makes them light but strong.
– Long bones can be found in the thigh, lower leg, toes, arms, forearms and fingers.
