Cartilage and Bone Tissue Flashcards
4 Main types of Tissue
Epithelium, Connective and Supportive tissue, muscle tissue, and nervous tissue
Consists of cells and extensive ECM of fibers and ground substance
Cartilage (supportive tissue)
Cartilage is covered by _
perichondrium
inner layer
chondrogenic layer (cellular)
outer layer
fibrous layer
unit of cartilages
Chondrion
cartilage is avaslucar
true
cartilage cells
chondroblast, chondrocytes, chondroclast
secrete the extracellular matrix (ECM) and
become less active
chondroblast
contained in a space called a
lacuna
are the less active cells, but maintain and repair the matrix of the cartilage cells
chondrocytes
multinucleated cartilage eating cells
chondroclast
Types of cartilage
hyaline, elastic, fibrocartilage
most common type
hyaline cartilage
Found in developing vertebrate skeleton, epiphyseal disc, articular cartilage, nose, larynx, trachea, bronchi, ventral end of ribs
hyaline cartilage
Matrix contains collagenous fibers
interterritorial matrix and territorial matrix
clusters of 2 - 4 chondrocytes occupying the
same lacuna
isogenous group
Similar to the structure of hyaline but with numerous
elastic fibers
elastic cartilage
elastic cartilage is found in epiglottis, parts of larynx and pinna, auditory tube
true
Transition of cartilage and connective tissue
fibroelastic cartilage
