Two-thirds of the weight of bone is accounted for by:
(a) Crystals of calcium phosphate
(b) Collagen fibers
(c) Osteocytes
(d) Calcium carbonate
Guida verificata passo dopo passo1
Understand that bone tissue is composed of both organic and inorganic components, which contribute to its strength and structure.
Recall that the inorganic portion of bone, which makes up about two-thirds of its weight, primarily consists of mineral crystals.
Identify the main mineral crystals in bone, which are primarily crystals of calcium phosphate in the form of hydroxyapatite.
Recognize that collagen fibers are the organic component providing flexibility, but they account for about one-third of bone weight, not two-thirds.
Conclude that the two-thirds of bone weight is mainly due to crystals of calcium phosphate, making option (a) the correct choice.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Bone Composition
Bone is a composite material made up of organic and inorganic components. The inorganic part mainly consists of mineral crystals, which provide hardness and strength, while the organic part, primarily collagen fibers, offers flexibility and resilience.

Bone Marrow
Calcium Phosphate Crystals
Calcium phosphate, mainly in the form of hydroxyapatite crystals, is the primary mineral component of bone. These crystals make up about two-thirds of the bone's weight and are responsible for its rigidity and load-bearing capacity.

Collagen Fibers in Bone
Collagen fibers are the main organic component of bone, providing a flexible framework that supports mineral deposition. They contribute to bone's tensile strength and help prevent brittleness.
