Connective Tissues Flashcards
name examples of connective tissues
bone
cartilage
tendons
adipose
what is the outermost layer of bone connective tissue
articular cartilage
what is under articular cartilage
cortical bone
what tissue is present on the inside of the bone tissue
spongey or cancellous bone (trabecular bone)
what are basement membranes
found under epithelial tissue and have collagen fibres
what are the three main components of connective tissues
ground substance
fibres
cells
what comprises the extracellular matrix of connective tissue
ground substance and fibres
what is the function of the ECM
provides cells with structural and biochemical support
what is the function of fibres in ECM
provide structural support and tensile strength
what are the two main types of fibres
collagen
elastin
what fibre provides strength
collagen
what fibre provides stretch and recoil
elastin
what type of collagen fibres are found in hyaline cartilage
type 2
how are fibres secreted into ECM
by connective tissue cells
what do blast cells do
synthesise ECM
what do cytes cells do
maintain ECM
what do clast cells do
break down ECM
what are the three types of connective tissues
connective tissue proper
skeletal connective tissue
fluid connective tissue
what is connective tissue proper categorised into
loose (mostly ground substance)
dense (mostly fibres)
what are examples of loose connective tissues
areolar
adipose
reticular
what are examples of dense connective tissues
regular
irregular
elastic
what are dense regular connective tissues
run in same direction - structural integrity
what are dense irregular connective tissues
run in different directions - strength in different planes
what are elastic dense connective tissue fibres
allows recoil after stretching
