Question

In what way are the humerus and the femur similar? An x-ray of the human body showing the humerus and femur bones A. They both attach their respective limbs to the axial skeleton. B. They both have similar joints at each end. C. They both are extremely strong and made only of compact bone. D. They both have hollow spaces filled with bone-generating cells. E. They both protect vital organs.

Answer 1

The humerus and femur are similar in that B) they both have similar joints at each end, making them long bones that function as levers in their respective limbs.

Step-by-step explanation:

In what way are the humerus and the femur similar? The correct answer is B. They both have similar joints at each end. Both the humerus and femur are classified as long bones, which means they are cylindrical in shape, being longer than they are wide.

These bones function as levers and move when muscles contract. The humerus is the only bone in the upper arm, and it forms part of the shoulder joint at its proximal end where it connects to the scapula, and the elbow joint at its distal end.

The femur is the single bone of the thigh, forming the hip joint at its proximal end with the pelvis, and the knee joint at its distal end with the tibia. Both have epiphyses covered with articular cartilage and diaphyses with a marrow cavity.

Despite being different in terms of location and the specific movements they facilitate, the structural similarity as long bones with joints at each end is notable.

Answer 2

The most appropriate answer would be option A.

The humerus and femur are the bones of the appendicular skeletal system.

They both attach their respective limbs to the axial skeletal.

The humerus is a long bone of the arms which connects it to the skeletal through scapula.

Similarly, the femur is a long bone of the thigh which connects the lower limb with axial skeletal through the pelvic joint.
