Osteoporosis
Osteoporosis
Your bones can become brittle and there is a greater risk of bone fractures.Osteoporosis (gaps, lower bone density, or weak points in solid bones) occurs primarily where calcium is not being added to the bones. Lack of calcium or vitamin D, and lowered estrogen in women, can cause osteoporosis.
Specifically is the deposition of crystals of calcium phosphate that cause the replacing cartilage by bone, that is, chondrocytes are replaced by osteoclasts.
The strength and rigidity of the bone is a result of the inorganic salts deposited in the matrix. Matrix is basically just large amount of non-cellular materials, which is what your bones are made of.
When the epiphyseal plate is replaced by bone, then growth at that bone stops.
A bone is replaced when is destroyed.
Weakened bones can result from an over-secretion of parathyroid hormone (PTH). Excess PTH leads to increased calcium release from bones into the bloodstream, which can result in bone resorption and decreased bone density. This condition, known as hyperparathyroidism, can ultimately make bones more susceptible to fractures and osteoporosis. Proper regulation of calcium and phosphorus levels is crucial for maintaining bone health.

Answer
Bones require large amounts of calcium and phosphorus. Also Vitamin D is important for bone development.
calcium
Bone cells take calcium and phosphorus from the blood to keep the bone hard and strong. These minerals are essential for bone mineralization and strength.
