cartilage/bones w/out images Flashcards
Exam 2
(3) cartilage
(1) hyaline
(2) elastic
(3) fibrocartilage
Bone tissue (2)
(1) compact
(2) spongy
hybrid of dense CT and hyaline cartilage
fibrocartilage
translucent, very hydrated, smooth
Hyaline
located at all auricular joint surfaces
Hyaline
found in external ear, eustachian tube, epiglottis
elastic
found in intervertebral discs, tempromandibular joint, pubic symphysis
fibrocartialge
double Ds
growing cartilage
interterritorial matrix
space between the cells
isogenous groups
back to back D
cells retracted from
lacunae
cartilage can grow both
interstitial and appositional
where new cartilage can form and contains fibroblasts
perichondrium
if the auricular surface is damaged what happens?
nothing, you cant grow new cartilage
wire that divides into V shape
elastic fiber
cartilage that has no prerichondrium
fibrocartilage
Fibrocartilage exhibit a
swirly pattern
where do you find lamellar bone?
Both spongy and compact
Where do you find haversian systems
Compact
Where do you find volkman
compact
bone can only grow
appositionally- on top of each other
canicculli will reach towards the
central canal where all of the blood supply is
Howship lacunae
osteoclast
bone-makers
osteoblasts
bone-brakers
osteoclasts
osteon not found in
spongy bone
immature bone
woven bone
CT that envelops the cartilage
perichondrium
cells are enveloped with this very basophilic cloud
territorial matrix
capsular matrix
surrounds the cell from the outside
true or false:
all forms of cartilage contain type II collagen
true
lamellar bone will be found in
both spongy and compact
unmineralized
osteoid
when does osteoid get calcified
within a day
bundles of collagen fibers that penetrate bone tissue in a perpendicular fashion
sharpey fibers
Extracelluar water plays a critical biomechanical role in this process. Which cartilage components is important to bind extracellular (interstitial) water?
Glycosaminoglycans
isogenous groups grow by _____ and found in ______
interstitial growth and found in cartilage
The chondrocyte capsule is intensely basophilic and metachromatic due to high concentrations of which one of the following?
proteoglycans
Which of the following is the most abundant type of collagen in bone tissue?
Type I collagen
Which cells is responsible for appositional growth of hyaline cartilage during growth and development?
Chondroblasts in the perichondrium
Which type of collagen is the principal protein which forms the three-dimensional meshwork in hyaline cartilage throughout the body?
Type II collagen
Osteoid differs from bone matrix with respect to
hydroxyapetite
osteoclasts are derived from
Mononuclear hematopoietic progenitor cells
