B2.1-B2.4 The Musculoskeletal system

These types of bone are hard and dense, providing structure, strength, and mobility. An example is the humerus in the arm. ​ (a)  

These types of bones vary in shape and structure (meaning they don’t fit into other bone categories). Their shape helps protect internal organs. For example, the vertebrae. ​ (b)  

These types of bones develop in tendons where their purpose is to reinforce and decrease stress on that tendon (protecting it). An example is the patella. ​ (c)  

These types of bones are made up of a layer of spongy bone between two flat layers of compact bone (giving a flat rather than rounded shape). They provide protection. For example, the bones forming the cranium ​ (d)  

These types of bones are roughly cube shaped and provide stability and movement. Examples are the carpals (in the wrist) and tarsals (in the ankles.) ​ (e)
