, 4 primaire weefsels in menselijk lichaam:
Prikkelbaar vs. niet- prikkelbaar:
- Niet-prikkelbare cellen/ weefsels
o kennen slechts 1 toestand, zijnde de ‘rust’-toestand
- (Selectief) prikkelbare cellen/ weefsels
o kennen een rusttoestand
o slaan om in een aangeslagen (actie-) toestand bij blootstelling
aan de gepaste prikkel (aan voldoende intensiteit)
zintuigcel ontlaadt en scheidt neurotransmittor (zie
verder) af bij het opvangen van een prikkel
zenuwcel geleidt zenuwimpulsen (zie verder) bij
blootstelling aan welbepaalde neurotransmittoren
spiercel contraheert (zie verder) na zenuwimpuls
kliercel scheidt stoffen af na zenuwimpuls of hormonale
(zie verder) blootstelling
