My notes for the response to stimuli topic. all images will be from the textbook/ save my exams

Explore the mechanisms of response to stimuli in organisms, including sensory receptors, reflex arcs, and plant growth factors. This summary covers key concepts such as neuron function, eye anatomy, and the role of hormones in plant responses. Ideal for AQA Biology students preparing for exams.

Response to Stimuli Overview

Revision note

Aaron Denton

AQA bio ch14 response to stimuli 

Process of firing an action potential. The all or nothing principle. The refractory period.

Explore the mechanics of action potentials, including the all-or-nothing principle, the role of ion channels, and the significance of the refractory period in neuronal communication. This summary provides a clear overview of how action potentials are generated and propagated in excitable tissues.
