Types of bones Flashcards
Long bones
Are bones that are longer than they are wide. They don’t have to be big, small bones like finger bones (phalanges) count as long bones. A long bone has a shaft plus two ends
Short bones
Are roughly the same size in length, width and thickness.
Flat bones
Flat bones,or plates, usually protect organs or offer a good surface for muscles to attach to. For example, the ribs protect the heart and lungs.
Irregular bones
Have odd shapes, and perform a range of functions. Some have a special shape so that they can protect something, like the vertebrae, which protect the spinal cord. Other have lots of attachment points for muscle.
Examples of long bone
All limb bones apart from knee cap (patella) and the wrist and ankle.
Examples of short bones
The only short bones in the body are the carpals in the wrist and the tarsals in the foot. To remember carpals and cuffs. Tarsals and toes.
Examples of flat bones
Ribs protect the heart and lungs, while the broad shoulder blade (scapula) has 3 main muscle groups attached to it. Other flat bones: kneecap (patella), skull (cranium), chest plate (sternum), collarbone (clavicle) and 2 hip bones.
Examples of irregular bones
The vertebrae, which protects spinal cord. Others have lots of attachment points for muscle, like the sacrum, a triangular bone in lower back.
