GENERAL HISTOLOGY

Detailed explanation-1: -Calcium as a nutrient is most commonly associated with the formation and metabolism of bone. Over 99 percent of total body calcium is found as calcium hydroxyapatite (Ca10[PO4]6[OH]2) in bones and teeth, where it provides hard tissue with its strength.

Detailed explanation-2: -Storage of inorganic salts The matrix of bone tissue is rich in calcium salts. Vital metabolic processes require calcium. A low blood calcium level stimulates cells in the bones called osteoclasts to break down bone tissue and release calcium ions.

Detailed explanation-3: -Bone mineral (also called inorganic bone phase, bone salt, or bone apatite) is the inorganic component of bone tissue. It gives bones their compressive strength.

Detailed explanation-4: -Calcium is an essential element that serves an important role in skeletal mineralization. More than 99% of the calcium in the body is stored in bone as hydroxyapatite. Calcium in this form provides skeletal strength as well as a reservoir for calcium to be released into the serum.
