Receptors | Pain Receptors, Touch Receptors & Its Types | New Biology Class 12 | Lec. 16 Welcome to Mubarak Ali Official! 🧬📚 In Lecture 16 of New Biology Class 12, Chapter 15 – Nervous System, we discuss Receptors, Pain Receptors, Touch Receptors and their Types in a simple, conceptual and exam-oriented way. 📌 Touch Receptors Covered in This Lecture: 1. Pacinian Corpuscles Important for detecting deep pressure, deep touch and vibration. 2. Meissner’s Corpuscles Specialized for light and fine touch. 3. Merkel Receptors / Merkel Discs Detect sustained touch and pressure and help in recognizing fine details of objects. 4. Hair Follicle Receptors Detect movement or displacement of hair, contributing to the sensation of light touch. 5. Ruffini Endings Associated mainly with skin stretch and sustained mechanical stimulation. 🔴 Pain Receptors This lecture also explains pain receptors (nociceptors), their basic role and how painful stimuli are detected and transmitted through sensory pathways. 🎯 Exam-Focused Concepts This lecture is especially useful for: FSc Part 2 Biology New Biology Class 12 Punjab Board Federal Board KPK Board Sindh Board Balochistan Board MDCAT preparation Biology conceptual MCQs Board short questions and long questions The lecture focuses on understanding the difference between various touch receptors, their functions and the type of stimulus they detect — making these concepts easier to remember for Board Exams and MDCAT MCQs. 📖 Chapter 15: Nervous System 🎓 Lecture 16: Receptors | Pain Receptors, Touch Receptors & Its Types Watch the complete lecture for a clear understanding of sensory receptors, pain receptors and touch receptors. 👍 Like | 📲 Share | 🔔 Subscribe to Mubarak Ali Official #BiologyClass12 #NewBiologyClass12 #Receptors #TouchReceptors #PainReceptors #PacinianCorpuscles #MeissnerCorpuscles #MerkelReceptors #RuffiniEndings #MDCAT2026 #PunjabBoard #FScBiology #MubarakAliOfficial
