FUNCTIE
= Waarnemen van (veranderingen in) de omgeving (of zichzelf) waardoor passend
gereageerd kan worden


BEGRIPPEN
Prikkel-zintuigcellen-zintuig(orgaan)

- Zintuigen: tuigen voor de zinnen (wat we kunnen waarnemen – vb:
smaak/reuk/zien)
 Dingen die je nodig hebt om de zinnen te kunnen waarnemen
 Zintuigorganen: ogen/oor/neus…
 In de zintuigorganen – zintuigcellen
 Zintuigcellen detecteren + geven prikkels (dingen die de zintuigen aanzetten
tot het geven van een signaal) door aan de hersenen

Prikkeldrempelwaarde

- Prikkels (= stimuli) moeten een bepaalde drempel overschrijden om een stimulus
te geven
- Om ervoor te zorgen dat dat zintuigcelletje een signaal gaat geven

Kan verschillend zijn per diersoort

Vb: ultrasone geluiden: voor ons geen prikkel – wij horen dit niet  vleermuizen wel
