What is Appositional growth and interstitial growth?
Appositional growth occurs when chondroblasts secrete new matrix along existing surfaces and this causes the cartilage to expand and widen. In interstitial growth, chondrocytes secrete new matrix within the cartilage and this causes it to grow in length.
What does interstitial growth mean in anatomy?
Interstitial growth is the process that adds or removes solid mass at locations inside a solid material. For this process to occur, there must be interstitial space within this material to allow atoms or molecules to bind to the underlying substrate.
What allows for interstitial growth?
In endochondral ossification, bone develops by replacing hyaline cartilage. Activity in the epiphyseal plate enables bones to grow in length (this is interstitial growth).
What does Appositional growth require?
Growth by forming new layers on the surface of pre-existing layers; process of increasing in thickness rather than length. In bones, this method of growth is accomplished by the addition of newly formed cartilage on the surface of the previously formed cartilage.
Which of the following statements best describes interstitial growth of cartilage?
Which of the following statements best describes interstitial growth of cartilage? Chondrocytes in the lacunae divide and secrete matrix, allowing the cartilage to grow from within. Which of the following is not a function of the skeletal system and bone tissue?
Which type of cartilage grows by interstitial growth instead of Appositional growth?
In endochondral ossification, bone develops by replacing hyaline cartilage. Activity in the epiphyseal plate enables bones to grow in length (this is interstitial growth). Appositional growth allows bones to grow in diameter.
Which of the following correctly describes an interstitial system found in compact bone?
Which of the following correctly describes an interstitial system found in compact bone? It is a set of lamellae that form an incomplete circle and is left over from an osteon that was degraded during an earlier episode of bone remodeling.
Is bone growth Appositional or interstitial?
Activity in the epiphyseal plate enables bones to grow in length (this is interstitial growth). Appositional growth allows bones to grow in diameter. Remodeling occurs as bone is resorbed and replaced by new bone.
What are the two types of cartilage growth?
Growth of cartilage is attributable to two processes:
- Interstitial growth which includes: Cell division of the chondrocytes. Synthesis of the extracellular matrix.
- Appositional growth which includes: Differentiation of the chondroblasts or perichondrial cells. Synthesis of the extracellular matrix.
Which statement best describes interstitial growth of cartilage?
Which of the following statements best describes interstitial growth of cartilage? Chondrocytes in the lacunae divide and secrete matrix, allowing the cartilage to grow from within.
What is interstitial growth of cartilage?
Cartilage can grow in two ways: Interstitial growth – chondrocytes grow and divide and lay down more matrix inside the existing cartilage. This mainly happens during childhood and adolescence.
Where does interstitial growth occur?
Interstitial growth is a bone growth which results in the lengthening of the bone. This growth occurs within the lacunae. It happens due to the cell division in the proliferative zone and the maturation of cells in the zone of maturation. Cartilage lengthens and is replaced by bone tissue during interstitial growth.
