Mark the following statements about bone tissue as true or false. If a statement is false, correct it to make a true statement.
a. The primary mineral in the inorganic matrix is hydroxyapatite.

Step 1: Understand the composition of bone tissue. Bone tissue is composed of an organic matrix (primarily collagen fibers) and an inorganic matrix (primarily mineral salts). The inorganic matrix provides strength and rigidity to the bone.
Step 2: Recall the primary mineral in the inorganic matrix. The main mineral in the inorganic matrix of bone is hydroxyapatite, which is a crystalline structure made of calcium and phosphate ions.
Step 3: Evaluate the statement provided. The statement says, 'The primary mineral in the inorganic matrix is hydroxyapatite.' Based on the information above, this statement is true.
Step 4: If the statement were false, you would need to correct it. For example, if the statement incorrectly identified the primary mineral, you would replace it with 'hydroxyapatite' to make it accurate.
Step 5: Conclude that the statement is true as written, and no correction is necessary in this case.

Concetti chiave

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

Bone Tissue Composition

Bone tissue is composed of both organic and inorganic components. The organic matrix primarily consists of collagen fibers, which provide tensile strength, while the inorganic matrix is mainly made up of minerals, predominantly hydroxyapatite, which gives bone its hardness and rigidity.

Hydroxyapatite

Hydroxyapatite is a naturally occurring mineral form of calcium apatite, represented by the chemical formula Ca10(PO4)6(OH)2. It is the primary mineral found in the inorganic matrix of bone tissue, contributing to its strength and structural integrity, and plays a crucial role in bone mineralization.

Bone Tissue Function

Bone tissue serves several essential functions, including providing structural support, facilitating movement by serving as attachment points for muscles, protecting vital organs, and storing minerals such as calcium and phosphorus. Additionally, bone tissue houses bone marrow, which is involved in blood cell production.
