A true statement regarding calcium in the bone matrix is that it exists primarily in the form of hydroxyapatite crystals, which provide structural rigidity and strength to bones. These crystals consist of calcium phosphate and are integral to bone mineralization, facilitating the storage of calcium and phosphate ions. This mineralization process is crucial for maintaining bone density and overall skeletal health.
What else can I help you with?
What is the function of the calcium salts in a bone?
Calcium salts in bone provide strength and rigidity to the bone structure. They help to mineralize the bone matrix, making it hard and capable of withstanding mechanical stress. Calcium salts also play a role in bone remodeling and storage of calcium for regulatory purposes in the body.
Is bone cell that maintains and monitors the mineral content?
Osteocytes are bone cells that maintain and monitor the mineral content of bone tissue. They help regulate the amount of minerals, such as calcium and phosphate, in the bone matrix through processes like bone remodeling and responding to mechanical stress.
What is the hard tissue that contains calcium?
Bone tissue appears almost exactly like the cross section of a tree. Each individual tree represents the functional unit of bone connective tissue, or an osteon. The center circle is called the Haversian, or central, canal. The blood and nerve supply of bone (remember, it's a living tissue; therefore, oxygen is delivered to bone via red blood cells and carbon dioxide is taken away) runs through the Haversian canal.
Has a hard rigid matrix with inorganic salt calcium carbonate ans calcium phosphate?
Yes, a hard, rigid matrix composed of inorganic salts such as calcium carbonate and calcium phosphate is characteristic of bone tissue. This matrix provides strength and support, allowing bones to withstand the mechanical stresses they encounter. The combination of these minerals, along with organic components like collagen, contributes to the overall structural integrity and functionality of bones in the skeletal system.
What happens through the action of osteoclasts?
Osteoclasts are responsible for bone resorption or the breakdown of bone tissue. They secrete enzymes and acids that dissolve the mineral component of bone, allowing the release of stored calcium and other minerals into the bloodstream. This process helps maintain calcium homeostasis, remodel damaged bone, and play a role in bone growth and repair.
Where at in the bones is calcium?
Calcium is found in the matrix of bone.
What are bones cells that liquefy bone matrix and release calcium to the blood called?
Bone cells that liquefy the bone matrix and release calcium into the blood are called Osteoclasts. Immature or matrix depositing bone cells are called osteoblasts.
What is the primary mineral found in bone matrix?
The primary mineral found in bone matrix is hydroxyapatite, a crystalline form of calcium phosphate. It gives bone its strength and rigidity by providing a framework for bone structure.
Bone cells that liquefy bone matrix and release calcium to the blood?
Osteoclasts
What has an extracellualar matrix?
Many things do but the best example is bone with a matrix made mostly of calcium.
Why can a bone not grow interstitially?
Because of the hard calcium salts in the matrix
What are two types os substances are stored in bone matrix?
The two main types of substances stored in bone matrix are calcium and phosphorus. These minerals contribute to the strength and density of bones, helping to maintain the structural integrity of the skeleton.
What disorder primarily affects the bone matrix and is due to the loss of a calcium salt?
what disorder primary affects the bone matrix and is due to the loo of calcium salt
Location of mineral salts in bone?
The bone matrix is hard due to the primary salt of calcium chloride.
What are bone cells that respond to the parathyroid hormone to destroy bone matrix and release calcium into the blood?
An osteoclast.
In bone the calcium phosphate forms crystals of?
Hydroxyapatite. This is a mineral that gives bone its strength and hardness. It consists of calcium and phosphate ions that combine to form crystals within the bone matrix.
What is the role of the bone salts and organic matrix in making bone both hard and flexible?
Bone salts (calcium, mainly) lend hardness; the protein-rich organic matrix permits some flexibility
