What are the 4 types of bones?
Long

What are long bones and how are they used?
They are bones longer than they are wide. Muscle attachment - They are vital to generate movement, strength and speed and act as levers. They enable the body to move when pulled by muscles.
What are short bones and how are they used?
They are generally the same size in length, width and thickness. Carpals and tarsals. Associated with weight baring, shock absorption and spreading loads. Play role in jogging and tennis.
What are flat bones and how are they used?
Usually protect organs or offer good surface for muscles to attach to. Help movement. For example the borad scapula has 3 muscles attached to it.
What are irregular bones and how are they used?
Have odd shapes and vary in functions. Offer protection. Vertebrae protect spinal column and allow head to move.
