Capitolo 4, Problema 9e

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
The ECM of bone tissue consists exclusively of calcium phosphate crystals.

Guida verificata passo dopo passo
1
Understand the question: The problem asks whether the extracellular matrix (ECM) of bone tissue consists exclusively of calcium phosphate crystals. If the statement is false, we need to correct it to make it true.
Recall the composition of the ECM in bone tissue: The ECM of bone tissue is composed of both organic and inorganic components. The organic component includes collagen fibers (primarily type I collagen), which provide tensile strength, while the inorganic component includes calcium phosphate crystals (in the form of hydroxyapatite), which provide compressive strength.
Evaluate the statement: The statement claims that the ECM consists exclusively of calcium phosphate crystals. This is incorrect because the ECM also contains organic components like collagen fibers.
Correct the false statement: A true statement would be: 'The ECM of bone tissue consists of both organic components (such as collagen fibers) and inorganic components (such as calcium phosphate crystals).'
Summarize the process: To determine the truth of such statements, always consider the full composition of the structure or tissue in question, and ensure that all components are accounted for in the description.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Extracellular Matrix (ECM)

The extracellular matrix (ECM) is a complex network of proteins and carbohydrates that provides structural and biochemical support to surrounding cells. In bone tissue, the ECM is not only composed of mineral components but also includes organic materials such as collagen fibers, which contribute to the tissue's strength and flexibility.

Bone Matrix

Calcium Phosphate in Bone

Calcium phosphate is a primary mineral component of bone, providing rigidity and strength. However, it is not the sole component of the bone ECM; it works in conjunction with organic materials like collagen and non-collagenous proteins, which play critical roles in bone formation and maintenance.

Bone Matrix

Bone Tissue Composition

Bone tissue is a dynamic structure composed of both organic and inorganic components. The organic matrix, primarily collagen, accounts for about 30% of bone mass, while the inorganic matrix, mainly calcium phosphate, constitutes about 70%. This combination allows bones to be both strong and resilient.
