 Registratie van veranderingen binnen en buiten het lichaam en coördineren van
zinvolle respons erop met als doel het handhaven van de homeostase maar ook
communicatie en veiligheid.
- Homeostase handhaving is ook een taak van het endocrien stelsel, maar dit
reageert trager en het effect is langer van duur
- Zenuwstelsel werkt sneller maar effect is kort (elektrische fenomenen)

INDELING ZENUWSTELSEL

 Centraal ZS
- Hersenen en ruggenmerg
 Perifeer ZS
- Zenuwbanen buiten hersenen en ruggenmerg
- Afferent deel  sensorische info
- Efferent deel  motorische info

2. Functioneel (fysiologisch):

, CELORGANISATIE IN ZENUWWEEFSEL
2 soorten cellen in zenuwweefsel:
1. Neuronen
 Eigenlijke zenuwcellen
 Voor overdracht, verwerking en opslag van informatie

2. Neuroglia
 Ondersteunend netwerk voor neuronen
 Fagocyten

3 soorten neuronen:
1. Sensorische neuronen
 Leveren informatie aan het CZS
 Afferent

2. Motorische neuronen
 Stimuleren of remmen perifeer weefsel
 Efferent

3. Interneuronen (associatieneuronen)
 Zitten tussen sensorische en motorische neuronen in
 Analysen inkomende info
 Coördineren uitgaande info
