Question

bones are classified as—
○ short, long, flat or irregular.
○ proximal, distal, medial or lateral.
○ hard, soft, medium or porous.

Explanation:

Bones are classified based on their shape. Short bones (e.g., wrist bones), long bones (e.g., femur), flat bones (e.g., skull bones), and irregular bones (e.g., vertebrae) are standard classifications. Proximal, distal, medial, lateral are terms for bone positions, not classifications. Hard, soft, etc., don't define bone types as per anatomical classification.

Answer:

Short, long, flat or irregular.
