Mineralized tendon structure

In particular, the gastrocnemius, or Achilles tendon structure of the domestic turkey and manner of mineralization tendon have been described...

The skeletal age, which is not necessarily identical with the calendar age of the individual, has an important impact on the fluorine uptake, because osteoporosis is a process that fundamentally influences the bone structure. The disease pattern becomes visible in material loss within both the trabecular and the compact bone structure. Furthermore, the mineral density even in a healthy individual is not uniform in compact bone, but is a function of bone stress at this skeletal position and is increased at the point where muscles and tendons are fixed.

Collagen is a major structural element in connective tissues skin, tendons, muscle, and internal organs. It combines with inorganic compounds in bones and teeth. Cartilage is collagen mixed in an amorphous gel. Dentine, which makes up the bulk of a tooth, is a mixture of collagen and hydroxyapatite (a mineral), and water. 

The skeletal system is a structural framework providing support, shape, and protection to the human body. Additionally, the skeletal system provides attachment sites for organs. The skeletal system also stores minerals and lipids and forms blood cells. Bones, cartilage, tendons, and ligaments are all organs of the skeletal system.

Since the collagen of mineralized connective tissues is the predominating organic constituent, it might be expected to differ substantially from the collagen of soft tissues, such as skin and tendon. In fact, hard and soft tissue collagens are surprisingly alike in their main structural aspects and amino add composition.
