Hoofdstuk 20 – Zintuigen
20.1 – De zintuigen
Zintuigen → receptoren/sensoren → waarnemen → prikkel → impuls →centra in de
hersenschors
4 typen receptoren:
 Chemische receptoren:
o Gevoelig voor verandering van de chemische samenstelling rond cellen
 Mechanische receptoren:
o Geprikkeld door een verandering van eigen celvorm
 Temperatuurreceptoren:
o Registreren temperatuurveranderingen
 Lichtreceptoren (fotosensoren)
o Licht is de prikkel voor deze zintuigcellen

Adequate prikkel = elk type receptor is gevoelig voor een bepaald soort prikkel

Reukslijmvlies → chemische receptoren
Ingeademde lucht → reukslijmvlies → chemische verbinding met trilharen → prikkel →
