The longest bone in the body is the

Step 1: Analyze the question The question asks which bone is the longest in the human body. We need to compare the four bones listed.

Step 2: Explain the concept The human skeleton has bones in the arms and legs (long bones). The bones of the legs bear the body's weight and help in walking and running, so they are the longest and strongest.

Step 3: Compare the options

• A. Humerus: the upper arm bone, running from the shoulder to the elbow. It is long, but shorter than the leg bones. (Note the correct spelling is "humerus".)
• B. Femur: the thigh bone, running from the hip to the knee. It is the longest, heaviest, and strongest bone in the body, at roughly a quarter of a person's height.
• C. Scapula: the shoulder blade. It is a flat bone, not a long bone, so it cannot be the answer.
• D. Tibia: the shin bone, running from the knee to the ankle. It is the second longest bone, but it is shorter than the femur.

Step 4: Answer The femur is the longest bone in the body, so the answer is B.

Tip: Remember "Femur = First (longest)", and the tibia comes second. The femur is in the thigh, and the thigh is the biggest part of the leg. The smallest bone in the body is the stapes in the ear, which is a common JAMB follow-up question.
