An adult human skeleton contains 206 bones, a dynamic and living tissue that provides crucial support and protection. The secret to their incredible durability lies in their unique composition, a composite material designed to answer the question: what makes bones strong and nonflexible?.

The human skeletal system holds nearly 99% of the body's total calcium and a majority of its phosphorus, making it the primary site for mineral storage. This essential function allows the body to maintain mineral homeostasis, providing a critical reservoir of calcium and other elements for vital physiological processes like muscle contraction and nerve function.

Over 99% of the body's calcium is stored in the skeletal system, making bone tissue the most significant mineral reservoir. This critical function is not just for structural support but is also essential for maintaining mineral balance throughout the body for various physiological processes.

Recent cell studies have shown that vitamin C, also known as ascorbic acid, is a powerful regulator of bone cell activity and can directly stimulate osteoblasts, the bone-forming cells. Beyond its well-known role in immune function, this essential nutrient is a critical cofactor for collagen synthesis and helps maintain bone tissue integrity by neutralizing harmful free radicals.

According to studies, a high prevalence of vitamin D deficiency is common in patients with Paget's disease of bone. While Paget's is not caused by a vitamin deficiency, understanding what vitamin deficiency is Paget's disease is often linked to is critical for effective management, as low vitamin D can significantly impact the condition's progression.

The human body maintains blood calcium within a tightly controlled, narrow range of approximately 8.5 to 10.2 mg/dL through an essential biological process known as negative feedback. This complex hormonal regulation is critical because proper calcium levels are vital for nerve function, muscle contraction, and blood clotting.

Over 99% of the body's total calcium is stored within the bones. As the body's primary reservoir for this essential mineral, the skeleton plays a pivotal and dynamic role in regulating calcium levels in the blood, a process known as calcium homeostasis.

Over 99% of the body's calcium is stored in the bones, which are far from static, lifeless structures. This article will explore what are bones made of, revealing the fascinating blend of organic and inorganic materials that give them both strength and flexibility, and the dynamic, living cells that constantly remodel this vital tissue.

The human body maintains a remarkably tight regulation of blood calcium levels, as a sudden 1% drop can trigger a hormonal cascade to address the deficit. When faced with a sustained drop in circulating calcium, the body activates a critical process to replenish its supply, relying on its largest mineral reserve: the bones.

Approximately 85% of the body's total phosphorus is stored within the skeletal system, locked within the hard matrix of bone. This essential mineral is not merely deposited but intricately incorporated, which is central to understanding how is phosphorus stored in bones and teeth for strength and integrity.
