  • Periosteum- The strong Fibrous membrane that covers the long bone where the bone is not covered by articulating cartilage.

 

  •  Articulating Cartilage- covers the epiphysis, it is a very thin layer of cartilage that acts as a cushion for the ends of the bone.

 

  • Medullary Cavity- The hollow area inside the diaphysis of a bone which contains soft yellow bone marrow

 

  • Epiphyses ( or ends of the bone)-consists of small spaces in the cancellous bone, filled with red bone marrow.

 

  • Diaphysis ( or shaft)- a hollow tube made of hard compact bone which gives a strong structure that is light enough to allow easy movement.

 

  • Compact bone- The hard and densse outer covering of the bone is known as compact bone.

 

  • Spongy bone (cancellous)-in the ends of long bones, there is a spongy containing many spaces that are filled with marrow.
