Bone is a composite material, like fiberglass (something hard [and thus brittle] in a matrix of a more flexible substance.
In fiberglass the glass makes the (fishing rod) strong, the plastic makes it tough.
In bone, the calcium salts make it strong and hard, the connective tissue makes it tough.
The purpose of a long bone is to support the body and provide structure, as well as assist in movement and mobility. Long bones also play a role in producing red and white blood cells in the bone marrow.
When a chicken bone is soaked in cola, the acidic nature of the cola can weaken the bone structure. Over time, the cola can dissolve some of the calcium and minerals in the bone, causing it to become softer and potentially break down.
The main function of the diaphysis is to provide structural support and protection to the long bone. It also serves as a site for muscle attachment and helps in the transmission of forces during movement.
Examples of long bones are the femur, tibia, and fibula of the leg, the humerus
Endosteum is a thin layer of connective tissue that lines the medullary cavity of a long bone. It contains osteoprogenitor cells that differentiate into osteoblasts to aid in bone growth and repair. Its function is to support bone growth and remodeling by providing a surface for bone-forming cells.

They provide passageways for blood vessels to enter the bone.
Plasticine is a modeling clay originally developed and patented in 1899. It iscomposed of calcium salts (e.g. calcium carbonate), petroleum jelly, and long-chain aliphatic acids (e.g. stearic acid).
The skeletal system is a major repository of calcium.

Epiphysis are found at both ends of a long bone. They are made of cancellous bone filled with marrow. They have a bulbous shape and function to provide attachments for muscles and give stability to joints.
Calcium The calcium for the eggshell comes from three sources - the diet, special bone called medullary bone (found in the cavity of all birds long bones) of pullets and the hens skeleton. The hen uses approximately 2.5 grams of calcium in the formation of one normal egg. When diet alone cannot supply this amount the calcium will be sourced internally.
The diaphysis is the main shaft of long bone. It is hollow, cylindrical in shape and thick, and composed of compact bone. It's function is to provide strong support without cumbersome weight and provides a space (medullary cavity) that contains precursors of blood cells.
Short bones are defined as being approximately as wide as they are long and have a primary function of providing support and stability with little movement.
The question as to whether a lack of calcium causes bone disease is still up for debate. For as long as I can remember the experts have been encouraging us all to take calcium suppliments, as well as drinking more milk & eating our broccoli, but recently new studies have shown that there is very little connection between bone disease and a lack of calcium intake. I say, keep drinking your milk & eating your veggies, but perhaps skip the expensive suppliments until more studies are done.
