Examples of Sensory Receptors and Their Stimuli

📚 Quick Study Guide

🔍 Sensory receptors are specialized structures that respond to specific stimuli in the internal or external environment of an organism. 🧬 They convert these stimuli into electrical signals that can be interpreted by the nervous system. 🌡️ Sensory receptors can be classified based on the type of stimulus they detect:
• 🌡️ Thermoreceptors: Detect changes in temperature.
• механически Mechanoreceptors: Detect mechanical stimuli such as pressure, touch, sound, and gravity.
• 💡 Photoreceptors: Detect light.
• 🧪 Chemoreceptors: Detect chemical stimuli such as taste and smell.
• 🤕 Nociceptors: Detect pain (tissue damage).
📝 Sensory transduction is the process by which a sensory receptor converts a stimulus into an electrical signal. 🧠 The intensity of the stimulus is often encoded by the frequency of action potentials generated by the sensory receptor.
