sheet-like meshwork; basement membranes
Term
elastin
Definition
branched, acidophilic, amorphous protein; microfibril scaffold
Term
stroma
Definition
fibers
Term
ground substance
Definition
amorphous, aqueous gel, water, and GAGs
Term
GAG types
Definition
chondroitin sulfate (CT), keratin sulfate (skin), hyaluronic acid, and heparin
Term
resident cells of CT
Definition
mesenchymal cells, fibroblasts, fibrocytes, reticular cells, macrophages, mast cells, pericytes, and adipose
Term
reticular cells
Definition
star shaped
Term
mast cells
Definition
participate in the inflammatory response
Term
pericytes
Definition
undifferentiated cells associated with small blood vessels; has own basement membrane
Term
transient cells of CT
Definition
plasma cells, pigment cells, and white blood cells
Term
types of CT
Definition
loose, dense irregular, and dense regular
Term
loose connective tissue
Definition
binds individual muscle fibers together
Term
dense irregular CT
Definition
binds individual axons in nerves; found in dermis and lymph nodes
Term
dense regular CT
Definition
found in tendons, ligaments, and apineuroses
Term
reticular CT
Definition
found in lymph nodes and bone marrow
Term
elastic CT
Definition
intensely eosinophilic; found in some tendons and walls of blood vessels
Term
mesenchymal cells
Definition
located in the inner portion of the perichondrium
Term
chondroblasts
Definition
responsible for cartilage matrix formation
Term
chondrocytes
Definition
develop from mesenchymal stem cells; responsible for cartilage matrix maintenence
Term
chondroclasts
Definition
develop from macrophages; cells responsible for the massive removal of cartilage
Term
chondrogenesis
Definition
mesenchymal cells differentiate into chondroblasts, which develop into chondrocytes
Term
types of cartilage
Definition
hyaline, elastic, and fibrocartilage
Term
hyaline cartilage
Definition
composed of few cells embedded in gel-like matrix; distributed in most weight-bearing bone forming sites, articular cartilage, airways, and support structures of nose and larynx
Term
elastic cartilage
Definition
few cells embedded in gel-like matrix with elastic fibers present; found in ear and parts of larynx
Term
fibrocartilage
Definition
coarse collagenous bundles in parallel/V-shaped orientation with limited matrix between bundles; found in intervertebral discs, tendon and ligament attachments and menisci
Term
perichondrium
Definition
"sleeve around the arm" of cartilage
Term
isogenous groups
Definition
"cell nests" that characterize interstitial growth of cartilage
Term
interstitial growth of cartilage
Definition
mitosis of chondrocytes; occurs in growing animals
Term
appositional growth
Definition
growth from perichondrium; mitosis of chondroblasts; growing and adult animals
Term
no repair ability
Definition
articular cartilage lacking perichardium
Term
cartilage nutrition
Definition
perichondrium and synovial fluid
Term
proteoglycan aggregates
Definition
hyleuronic acid core with proteoglycan attached; GAGs attached to proteoglycan
