What are immature or matrix-depositing bone cells?
Immature or matrix-depositing bone cells are osteoblasts. These cells are responsible for bone formation by secreting collagen and other proteins that make up the bone matrix. Osteoblasts play a crucial role in bone growth and remodeling.
What is appositional bone growth?
Appositional bone growth is a process where bone tissue is added on the surface of existing bones, increasing their diameter and strength. This type of bone growth occurs throughout life in response to mechanical stress and helps bones adapt to changing physical demands.
The factor that determine where bone matrix is to be remodeled is?
The factors that determine where bone matrix is to be remodeled include mechanical stress on the bone, hormonal factors, and local growth factors. Osteocytes sense these factors and signal bone remodeling to maintain bone strength and integrity.
What is the process called when bones increase in width?
The process of bones increasing in width is called appositional growth. This occurs when new bone tissue is added to the existing bone surface, resulting in an increase in bone diameter.
What are the cells that produce organic matrix in bone?
The cells that produce the collagen and inorganic salts of bone matrix are osteocytes. Osteocytes maintain the protein and mineral content of the bone matrix. Osteogenesis is the production of new bone matrix.
What is a functional matrix?
In the development of vertebrate animals, the functional matrix hypothesis is a phenomenological description of bone growth.
What are immature or matrix-depositing bone cells?
Immature or matrix-depositing bone cells are osteoblasts. These cells are responsible for bone formation by secreting collagen and other proteins that make up the bone matrix. Osteoblasts play a crucial role in bone growth and remodeling.
What is it called when the immature or matrix-depositing bone cells are referred to as?
The immature or matrix-depositing bone cells are referred to as osteoblasts. These cells are responsible for synthesizing and depositing bone matrix during the process of bone formation. Osteoblasts play a crucial role in mineralizing the bone tissue, contributing to the growth and repair of bones.
The role of vitamin C in bone growth is that it?
is needed for proper collagen syntheis and is necessary for osteoblasts to create healthy bone matrix
What structures allow the bones to grow widthwise?
Bones grow widthwise through a process called appositional growth, which occurs at the periosteum, the outer layer of bone. Osteoblasts, cells responsible for bone formation, deposit new bone matrix on the outer surface, while osteoclasts resorb bone from the inner surface of the medullary cavity. This coordinated activity allows bones to increase in diameter while maintaining their shape and structural integrity. Additionally, the growth of the bone's width is also influenced by mechanical stress, which stimulates bone remodeling.
What is appositional bone growth?
Appositional bone growth is a process where bone tissue is added on the surface of existing bones, increasing their diameter and strength. This type of bone growth occurs throughout life in response to mechanical stress and helps bones adapt to changing physical demands.
The factor that determine where bone matrix is to be remodeled is?
The factors that determine where bone matrix is to be remodeled include mechanical stress on the bone, hormonal factors, and local growth factors. Osteocytes sense these factors and signal bone remodeling to maintain bone strength and integrity.
What cell removes bone matrix?
Osteoclasts are the cells responsible for removing bone matrix during the process of bone remodeling. They break down the mineralized bone matrix by secreting acids and enzymes, allowing for new bone formation by osteoblasts.
Do osteons grow from the inside out or the outside in?
Osteons, the structural units of compact bone, grow from the inside out. They develop through a process called appositional growth, where new layers of bone tissue are added to the outer surface of existing bone. As osteoblasts create new bone matrix, the central canal and surrounding layers expand, allowing for the growth of the osteon outward. This process helps maintain the strength and integrity of the bone as it adapts to mechanical stresses.
Does appositional or interstitial growth occur in the periosteum?
Appositional growth occurs in the periosteum, where new bone tissue is added to the surface. Interstitial growth, on the other hand, occurs within the bone itself, at the epiphyseal plates during growth.
What is the medical term meaning benign growth on the surface of a bone?
Osteomas is a general term for a bony growth on the surface of a bone, but there are many more specific diagnoses depending on the morphology of the tumor. A more specific type of benign tumor on the surface of bone is an osteochondroma, made up of both bone and cartilage. Exostosis is another type of bony growth on bone.
What happens during the appositonal growth?
bone is added to the outer surface
