supporting connective tissue.
a.hyaline cartilage
amorphous (Chondroitin and glucosamine) matrix that surrounds cells=chondrocytes within lacunae)
locations=embryotic skeleton costal cartilages, cartilage of the nose, trachea and larynx
function=support
avascular=no healing
b.elastic cartilage
same as above plus elastic fibers(purple)
locations=external ear, epiglottd
functions=maintenance of shape plus flexibility
c. Fibrocartilage
less firm than above;
locations=intervetable discs, pubic, symphis
functions= tensile strength plus shock absorber
d. Bone
hard, calcified matrix with collagen fibers 9tensile strength) and cells=osteocyes within lacunae)
location-bones of the skeleton
functions=preotection, support, movement, calcium store and hematopoiesis
highly vascular=fast healing
Note concentric of compact bone
