Name 6 types of connective tissue
CT Proper: Areolar (loose)
CT Proper: Adipose (fat)
Cartilage: Hyaline Cartilage
Cartilage: Elastic Cartilage
Cartilage: Fibrocartilage
a type of loose connective tissue
areolar connective tissue
CT Proper
areolar connective tissue modified to store nutrients; a connective tissue consisting cheifly of fat cells
adipose tissue
CT Proper
the most abundant cartilage type in the body; provides firm support with some pliability
hyaline cartilage
cartilage with abundant elastic fiber; more flexible than hyaline cartilage
elastic cartilage
the most compressible type of cartilage; resistant to stretch. forms vertebral discs & knee joint cartilages
young, actively mitotic cell that forms the fibers of connective tissue
the most abundant of the three fibers found in the matrix of connective tissue
collagen fiber
fiber formed from the protein elastin, which gives a rubbery & resilient quality to the matrix of connective tissue
elastic fiber
ground substance
the cellular material surrounding the nucleus & enclosed by the plasma membrane
control center of a cell;
fibrous, connective-tissue membrane covering the external surface of cartilaginous structures
actively mitotic cell of cartilage
mature cell of cartilage
soft packaging material to cushion & prtoect organs is what type of tissue
CT Proper: Areolar (loose)
insulation for body tissue & a source of food is what type of tissue
CT Proper: Adipose (fat)
What connective tissue (CT) is most common and found in bone joints?
cartilage: hyaline
The ear is what type of connective tissue?
cartilage: elastic
(moves easily)
What type of connective tissue (CT) is the least flexible; tissue between the vertebraes
cartiage: fibrocartilage
Haversian system is also known as what?
system of interconnecting canals in the microscopic structure of adult compact bone; unit of bone
osteon or
Haversian system
Volkmann's canals are also known as what?
perforating canals
canals that run at right angles to the long axis of teh bone, connecting the vascular & nerve supplies of the periosteum to those of the central canals & medullary cavity
perforating canals or
Volkmann's cananls
extremely small tubular passage or channel
a layer, such as of bone matrix in an osteon of compact bone
embryonic formation of bone by the replacment of calcified cartilage; most skeletal bones are formed by this process
endochondral bone formation
or ossification
endochrondral bone formation is also known as what?
the formation of a long bone typically begins in the center of teh hyaline cartilage shaft in this region
primary ossification center
*Begins at the center of the epiphysis and proceeds radially
*Leaves cartilage at the articular surface
Leaves cartilage at the interface between the epiphysis and diaphysis -> epiphyseal plate
*usually at the time of birth
secondary ossification center
double layered connective tissue that covers & nourishes the bone; "around bone"
dense outer layer that looks smooth & solid to the naked eye
compact bone
central cavity of a long bone
marrow cavity or
medularry cavity
marrow cavity is also known as what?
medularry cavity
plaste of hyaline cartilage at the junction of the diaphysis & epiphysis that provides for growth in lenth of a long bone
epiphyseal plate
connective tissue membrane covering internal bone structures
strut or thin plate of bone in spongy bone
bone forming cells
large cells that reabsorb or break down bone matrix
List (in order) the 5 zones of endochondral ossifaction in a developing long bone
1.Reserve Zone
2.Proliferative Zone (Growth)
3.Maturation Zone (transformation)
5.Ossification/Resorption Zone (osteogenic)
In what zone do cartilage cells undergo mitosis?
Proliferative Zone (growth)
In what zone do older cells enlarge; matrix becomes calcified; cartilage cells die; matrix begins deteriorating?
Maturation Zone & Calcification (transformation)
In what zone does new bone foramtion occur?
Ossification/resportion zone (osteogenic)
The ______ runs parallel to the long axis of the bone & carries blood vessels, nerves & lymph vessels through the bony matrix.
central (Haversian) canal
