Term
In which type of cartage is the perichondrium not present.
Definition
Fibrocartilage and on articular surfaces
Term
What cartilage serves as a temporary skeleton?
Definition
Hyaline
Term
What chondrocytes in groups of 2
Definition
Hyaline cartilage
Term
What is the only cartilage type that has type 1 collagen instead of 2.
Definition
fibrocartlage
Term
What is the territorial matrix and what is it composed of?
Definition
it is the area around the lacuna that houses the chondrocytes

It is composed of proteoglycans that stain deeper.
Term
What layer of the perichondrium is fibronous and which one is cellular
Definition
outer is fibronous and the inner is cellular.
Term
What does the perichindrum do?
Definition
Houses chondrogenic cells and chondroplasts and is provide the nearest blood supply
Term
What are condroblasts?
Definition
The manufacture the carilage matrix

precusures of Chondroblasts

Not housed in lacunae
Term
What are Chondrocytes?
Definition
Housed in lacunae

In inner layer of cartilage
Term
What are isogenous groups?
Definition
groups of four to eight cells in cartilage
Term
Discribe interstitial grouth and appositional grownth.
Definition
Interstitial is division of preexisting cells

Appositional results from differentiation of genic cells
Term
What is the ground substance in bone composed of?
Definition
Osteocalcin, a glycoprotein
Bone sialoprotine
Ca
type one collagen
Term
What do sharpey fibers do?
Definition
They connect the inner layer of the Peristium to the pone surface
Term
What is the ultimate supply of blood to the bone?
Definition
periosteum
Term
What do osteoblast secrete and what specific receptors do they have?
Definition
osteoid-uncalcified bone matrix

PTH receptors
Term
What are the characteristics of Osteocytes?
Definition
housed in there own lacunae

have cytoplasmic processes that extend threw calculi for nourishment

Gap junctions for information sharing.
Term
What are the characteristics of ostioclasts?
Definition
motile, multinucliated, reabsorb bone
Term
Color wise what is the difference between primary bone and secondary bone
Definition
primary is bluish
Secondary is more pink
Term
What are haversian systems
Definition
the circular complexes in bone
Term
what are Volkmann canals
Definition
connect harvistan canal with the peri or episteum
Term
What type of bone contains lamellae
Definition
Secondary bone
Term
Name the zones of the epiphyseal plates and there function
Definition
Zone of reserve - cartlage
proliferation- of chondrocytes(cell division
hypertrophy-enlargment of chondrocytes
calcificaton-chondrocyetes die and cartilage becomes calcified
ossification-ostioblasts elaborate on matrix
Term

and movable
Definition
imm-syntarthrosis
move-diarthrosis or snovial
