,HOOFDSTUK 1: EPITHEEL
1. WEEFSEL IN HET ALGEMEEN
Weefsels zijn structuren die gevormd worden door groeperingen van cellen met veelal een gelijksoortige vorm en functie,
m.i.b. van hun intercellulaire materie
4 primaire weefsels:
- Epitheel of dekweefsel
- Bind- en steunweefsel
- Spierweefsel
- Zenuwweefsel
4 primaire weefsels zijn met elkaar vermengd in verschillende verhoudingen
2. EPITHEELWEEFSEL
2.1. FUNCTIE EN OORSPRONG
Functie:
- Bekleden of bedekken van oppervlakken (huid)
- De opname van stoffen (darmwand)
- De afscheiding van stoffen (klieren)
- Het opnemen van prikkels (neuro-epitheel)
- De samentrekking (myo-epitheel)
Afkomstig van de drie embryonale kiembladen:
- Ectoderm (huid, mond, neus en anus)
- Entoderm (ademhalingswegen, spijsverteringskanaal en de klieren daarvan)
- Mesoderm (nieren …)
2.2. VORMEN VAN EPITHEELCELLEN
De vorm en afmetingen van epitheelcellen zijn zeer verschillend
→ gebruikelijke veelhoekige vorm is het gevolg van het dicht opeengepakt zijn tot dunnen of dikke lagen
- Langgerekt in cilindercellen (vb. darmkanaal vanaf slokdarm)
- Rond in kubische cellen (vb. nierbuisjes)
- Zeer plat in plaveiselepitheel (vb. lis van Henle)
, 2.3. CLASSIFICATIE VAN EPITHEELCELLEN
2.3.1. BEDEKKEND EPITHEEL
EENLAGIG EPITHEEL
- Plat (plaveiselepitheel)
- Kubisch
- Cilindrisch
MEERLAGIG EPITHEEL
- Verhoornend meerlagig plaveiselepitheel - Overgangsepitheel
o Huid o Urinewegen, blaas
o Onderaan: kubisch tot cilindrisch o Bolvormige cellen
o Bovenaan: zeer platten hoornschilfers → vorm verandert afh. van de vulling
- Niet-verhoornend meerlagig plaveiselepitheel - Meerrijig epitheel (pseudomeerlagig)
o Mond o Lijkt meerlagig doordat de kernen op
o Slijmvliezen die vochtige holten verschillende hoogten liggen
bekleden o Trilhaarepitheel van de luchtwegen
o Kubisch tot cilindrisch (geen
hoornschilfers) - Neuro-epitheelcellen
o Van epitheliale oorsprong
- Meerlagig cilinderepitheel o Gerangschikt in epitheliaal verband
o Urethra o Gespecialiseerd in sensorische functies
o Conjunctiva van het oog, uitvoergangen
van sommige klieren en urethra - Myo-epitheliale cellen
o Van epitheliale oorsprong
o Mogelijkheid tot contractie
o Secretoire gedeelten van zweetklieren,
speekselklieren en melkklieren
