TESTE DEIN WISSEN

What is the extracellular matrix made of and what do they do?

Lösung anzeigen
TESTE DEIN WISSEN

In cartilage the extracellular matrix is made of collagen together with proteins with long sugar chains attached to them (proteoglycans), which trap water and expand

TESTE DEIN WISSEN

What are the four things cartilage is formed of?

Lösung anzeigen
TESTE DEIN WISSEN

Cartilage is formed of chondroblasts and chondrocytes, collagen fibres and the hydrated
proteoglycans or 'ground substance'

TESTE DEIN WISSEN

What is the role of collagen fibres?

Lösung anzeigen
TESTE DEIN WISSEN

The collagen fibres provide strength to resist stretch
and the proteoglycan-trapped water allows cartilage to spring back into shape following
deformation

TESTE DEIN WISSEN

What is perichondrium in cartilage?

Lösung anzeigen
TESTE DEIN WISSEN

vascularized connective tissue sheath rich in collagen that surrounds
cartilage. It contains fibroblasts that secrete the materials for the collagen fibres. The inner
layer (next to cartilage matrix) contains fibroblasts/undifferentiated mesenchyme cells that
can differentiate to form chondroblasts

TESTE DEIN WISSEN

What are chondrocytes?

Lösung anzeigen
TESTE DEIN WISSEN

mature cartilage cells that are embedded in rigid extracellular matrix.
These cells reside in small spaces within the matrix called lacunae. There may be more than
one cell per lacuna. Chondrocytes in hyaline cartilage that are grouped together are called
isogenic groups.

What are chondroblasts?

Lösung anzeigen
TESTE DEIN WISSEN

immature cartilage cells. They secrete extracellular matrix, but are not yet
rigidly embedded in that matrix.

What are the three types of cartilage?

Lösung anzeigen
TESTE DEIN WISSEN

Hyaline Cartilage

Elastic Cartilage

Fibrocartilage

TESTE DEIN WISSEN

What is hyaline cartilage composed of?

Lösung anzeigen
TESTE DEIN WISSEN

Hyaline cartilage is composed of type II collagen and chondromucoprotein, a copolymer of
chondroitin sulfates and protein. Hyaline cartilage is found in the nose, trachea, where ribs join the sternum, and at the epiphyseal plate of long bones.

TESTE DEIN WISSEN

What is elastic cartilage composed of?

Lösung anzeigen
TESTE DEIN WISSEN

Elastic cartilage contains abundant elastic fibres, type II collagen and numerous cells.  It is found in the external ear (auricle) and the epiglottis.

TESTE DEIN WISSEN

What does the process of mineralization in bones create to form a stable bone structure?

Lösung anzeigen
TESTE DEIN WISSEN

In bones, the process of
mineralization generates calcium hydroxyapatite to make the stable bone structure. This
brings new challenges, as remodelling bone requires local dissolving of the bone and
regeneration of new bone.
