These cells are encased within the matrix and occupy small spaces called lacunae: cartilage serves three major functions: Provides a model for the formation of bone in the body. This is the most common bone shape: examples: femur, humerus, tibia, etc, short bones lave a length nearly equal to their width. The largest bone of this type in the body is the patella: flat bones have flat, thin surfaces. Composed of parallel surfaces of compact bone with a later of internally placed spongy bone: examples: scapula, roof of the skull, sternum, ribs, irregular bones have elaborate, complex shapes. Long bones; they are longer than they are wide. Cells of the bone: osteoprogenitor: stem cells derived from the mesenchyme.
