cartilage
is an avascular connective tissue. has less ground substance than connective tissue.
three types of cartilage
hyaline, elastic, and fibrocartliage
Hyaline cartilage
chrondrocytes cells singele or paired in lacunae
small amount of ground substace with collagen fibers
locations of the hyaline cartliage
supportive rings of the trachea, lines the articular surfaces of opposing bones providing a smooth surface for movement
elastic cartilage
chondrocytes singgle or paired in lacunae
small amount of ground substance with collagen fiers and many elasttic fibers which allow more flexibiblity than hyaline cartilage
elastic cartilage locations
pinn of ear and epiglottis
fibrocartilage
chondrocytes in lacunae are less numerous and may be arranged in rows
ground substance with parallel bundles of collagenous fibers fro strength
fibrocartilage locations
intervertebral disces pubic symphsis menisci of the knee

fibrocartilage
bone
specialized vascular connective tissue
contain 99% of the body's total calcium stores
two types of bones
both composed of the same cell types and fibers and ground substance
cell types found in bones
mature oseocytes in lacunae
ostoblasts at free edges
wandeering, multinucleated osteoclasts resorb bone
osteogenic cells bone stem cells
stem cells make
osteoblasts
Matrix
extremely small amount of ground ubstance
dense, embedded collagen fibers that have become ossifed with hard inorganic mainerals called hydroxyapatite
