Join community: https://chat.whatsapp.com/Ex2HoFX7V67...

In today’s session with Maxwell Sir, we are going to learn one of the most asked biology topics – Sense Organs, especially Eye and Ear, from the human anatomy section for exams like Railway Group D, NTPC, SSC GD, CDS, NDA, Airforce X/Y Group, and State Police exams.

✅ What is Covered in this Video:
🔹 Eye Structure (आँख की संरचना)
🔹 Parts of the Eye – Cornea, Iris, Pupil, Retina, Lens
🔹 Working of Human Eye
🔹 How we see objects – Refraction of Light in Eye
🔹 Defects of Vision – Myopia (Short Sightedness), Hypermetropia (Long Sightedness), Presbyopia, Astigmatism
🔹 Corrective Measures – Concave/Convex Lenses
🔹 Function of Retina and Rods/Cones
🔹 Blind Spot, Aqueous Humour, Vitreous Humour

🔸 Ear Structure (कान की संरचना)
🔸 Outer, Middle, and Inner Ear Explained
🔸 How Sound Travels – Ear Drum to Cochlea
🔸 Parts like Ear Canal, Tympanic Membrane, Ossicles (Malleus, Incus, Stapes)
🔸 Eustachian Tube, Semicircular Canals, Auditory Nerve
🔸 Function of Cochlea and Balance Maintenance
🔸 Common Hearing Defects and Remedies

📚 Why This Video is Important:
Railway Group D और SSC जैसे exams में biology section से हर साल Sense Organs पर कई questions पूछे जाते हैं। इस वीडियो में:

✅ Concept को आसान भाषा में समझाया गया है
