Bindweefsel


Bindweefsel -> bindweefselcellen

Extracellulaire matrix
= intracellulaire stof die zorgt voor de scheiding van bindweefselcellen
-> collagene of elastische vezels

1. ALGEMEEN BINDWEEFSEL

• Areolair (losmazig) bindweefsel:
- Ijl netwerk van schaarse collagene elastische vezels
- Overvloedige extracellulaire matrix
-> bevat verschillende celtypes

• Dicht bindweefsel:
- Ongeordend (= onregelmatig)
- Geordend (= regelmatig)

-> 1 grote vetvacuole (= univacuolair)
-> sterk afgeplatte kern tegen celmembraan
-> bloedplaatjes tussen vetcellen

• Bruin vet:
-> geïsoleerd of verspreid tussen andere cellen
-> kleinere cellen
-> talrijke kleine vetvacuolen (= plurivacuolair)
-> afgeronde kern (niet tegen membraan)
2.2. STEUNWEEFSELS

Kraakbeenweefsel
-> semi-rigide
-> drukbestendig (aanwezigheid op gewrichtsvlakken)
-> vormbestendig
-> geen zenuwen en bloed- en lymfevaten

• Kraakbeencellen = chondrocyten
-> in extracellulaire matrix (bevat collagene en elastische vezels)

• Hyalien kraakbeen:
= meest algemene type van kraakbeen
-> kleine groepjes kraakbeencellen
-> homogene EC matrix
