Structure

The structure of bones is a combination of living and dead cells embedded in a matrix. The outer hard layer of the bone is referred to as compact bone and has few spaces. The internal part of bone also called spongy tissue is porous and harbors the bone marrow and blood vessels. Other tissue found in bone includes endosteum, periosteum, and nerves. Bone matrix has organic (mineral) components and inorganic components such as collagen Bone formation is the result of hardening of this matrix.
 
Cartilage essentially consists of chondrocyte cells which produce an extracellular matrix consisting of collagen fibres, proteoglycan, and elastin fibres. Different types of cartilage contain these components in different proportions. Cartilage, unlike bones, does not contain blood vessels.

Thanks JohnWheat,

 

That is pretty much spot on what I would define it as, however I just wondered if there is a clear definition set our by either FSA or DEFRA & what is & or is not accepted as possible  'edible components'
