Master Sensory Receptors fast ⚡ – clear explanations, OCR-aligned.
You’ll cover
• The role of sensory receptors in detecting changes (stimuli) in the internal or external environment.
• Key terms including stimulus, sensory receptor, transducer, generator potential and threshold potential.
• How different receptor types detect specific forms of energy such as light, pressure, chemicals and temperature.
• The process of sensory transduction and how stimuli are converted into electrical signals.
• The structure and function of the Pacinian corpuscle as a mechanoreceptor detecting pressure.
What’s included
• Labelled diagram showing examples of sensory receptor types.
• Table summarising stimuli types, receptor classes and common locations in the body.
• Diagram explaining sensory transduction and how stimuli generate electrical signals in receptors.
• Table outlining different gated ion channel mechanisms involved in receptor function.
• Labelled Pacinian corpuscle structure diagram showing lamellae, capsule and nerve ending.
• Diagram showing how pressure deforms lamellae to open stretch-mediated Na⁺ channels.
