Question

Which of the following four groups of bones, based on shape and with an example of each, is correct?

A) Long bones - Example: Femur
B) Flat bones - Example: Vertebra
C) Irregular bones - Example: Tibia
D) Round bones - Example: Sternum

Answer 1

The correct grouping and example of bone types by shape for the options provided is A) Long bones - Example: Femur. The femur is an example of a long bone, which is cylindrical and longer than it is wide. Other options either misclassified the bone type or provided an incorrect example for the specified type.

Step-by-step explanation:

The question asks about the correct grouping of bone types by their shape with an appropriate example for each type. Let's review the options given:

• Long bones - Example: Femur
• Flat bones - Example: Sternum
• Irregular bones - Example: Vertebrae
• Short bones - Example: Carpals of the wrist

Now, we check each option against the definitions:

• A) Long bones:

Correct. Long bones are cylindrical and longer than they are wide. The femur is a classic example of a long bone.

• B) Flat bones:

Incorrect. Flat bones, like the sternum, are typically thin and often curved.

• C) Irregular bones:

Incorrect. Irregular bones have complex shapes, and the tibia is not one of them. It is actually a long bone. The vertebrae would be a correct example of an irregular bone.

• D) Round bones:

This category does not exist but seems to refer to sesamoid bones. The sternum is a flat bone, not a round or sesamoid bone.

The correct pairing based on shape with an appropriate example, therefore, is A) Long bones - Example: Femur.
