Questions: What shape is the humerus? Short Flat Irregular Long

The answer is the fourth one: Long.

Explanation for each option:

• Short: Short bones are typically as wide as they are long, like those found in the wrist and ankle. The humerus does not fit this description.

• Flat: Flat bones are thin and often curved, such as the bones of the skull and the sternum. The humerus is not flat.

• Irregular: Irregular bones have complex shapes that do not fit into other categories, like the vertebrae. The humerus is not irregular.

• Long: Long bones are longer than they are wide and have a shaft with two ends. The humerus, being the upper arm bone, fits this description.

In summary, the humerus is classified as a long bone.
