Long bones
Long bones are longer than they are wide, they dont have to be big. Small bones like finger bones are counted as long bones.
In sport they are good for movement strength and speed.
Short bones
Short bones are genrally the same size in length, width and thickness. The only short bones in the body are the carpals (cuffs) in the wrist and the tarsels (toes) in the foot.
In sport short bones are usually associated with weight baring, shock absorption and spreading loads.
Flat bones
Flat bones ussually protect organs or offer a good surfce for muscles to attatch to. For example the ribs protect the heart and lungs.
In sport flat bones protect your organs in contact sports and provide attatchment for muscles.
Irregular bones
Irregular bones have odd shapes and vary in function. An example is the vertbrae which help protectors the spinal column and the sacrum.
In sport irregular bones offer protection when playing sport, they tend to form specific functions.
5 functions of Skeletal System
Protect vital organs
Muscle attatchment
Movement
Makes red and white blood cells
Stores calcium
4 classifications (Types of bones)
Short bones
Long bones
Irregular bones
Flat bones
4 joints
Ball and socket joint
Hinge joint
Pivot joint
Condoloid joints
What is a joint used for?
Joints are ued for a specific type of movement.
When would a function of the muscularskeletal system be benefitiol?
When in boxing the bones will protect your vital organs from getting injured whilst taking a punch.
