Reflex


Reflex
Reflex, auf einen spezifischen Reiz hin arttypisch in stereotyper Form ablaufende, nervös ausgelöste Reaktion, die auf einem Reflexbogen basiert. Liegt der den Reiz aufnehmende Rezeptor im gleichen Organ wie der Effektor, handelt es sich um einen Eigenr. (z.B. der Dehnungsr. der Wirbeltiere), liegen Rezeptor und Effektor in verschiedenen Organen (z.B. Pupillenr.), spricht man von einem Fremdr. Während unbedingte R. wie der Kniesehnenr. angeboren sind, erfolgt die Antwort beim bedingten R. auf einen Reiz, der diese Reaktion ursprünglich nicht auslöste ( klassische Konditionierung).
