In this 113th masterclass session, RCI-registered special educator and psychologist Ms. Chetna Chhikara explores the intricate biological mechanisms and clinical impairments associated with human sensory systems. Moderated by the Personality Care Foundation team, the masterclass provides a comprehensive deep dive into the anatomy and physiology of both the human ear and eye, detailing how physical sound and light waves are processed, the distinct classifications of hearing and vision loss, and common sensory disorders.The session covers the three compartments of the ear and different forms of hearing loss (conductive, sensorineural, mixed, central, and ANSD), the optical anatomy of the eye, and vision disorders such as myopia, hyperopia, presbyopia, cataracts, and color blindness, concluding with an interactive Q&A session.
🔑 Key Highlights & Themes Covered (Timestamps)
🧠 Part 1: Anatomy of the Human Ear & Hearing Impairments
[04:54] — Structure of the Human Ear: Breaking down the outer ear (pinna and auditory canal), middle ear (tympanic membrane and the three smallest bones—malleus, incus, and stapes amplifying pressure 20-fold), and the inner ear (cochlea and semicircular canals) [04:54].
[12:03] — Types of Hearing Loss: Differentiating between Conductive Hearing Loss, Sensorineural Hearing Loss, Mixed Hearing Loss, Central Hearing Loss, and Auditory Neuropathy Spectrum Disorder (ANSD) [12:03].
👁️ Part 2: Anatomy of the Human Eye & Vision Disorders
[17:03] — Structure of the Human Eye: Exploring the cornea, iris (controlling pupil size like a shutter), ciliary muscles, lens, vitreous humor, and the light-sensitive retina (rods and cones) [17:03].
[24:23] — Common Vision Disorders: Analyzing Myopia (near-sightedness corrected with concave lenses), Hyperopia (far-sightedness corrected with convex lenses), Presbyopia (age-related bifocals), Cataracts (milly lens clouding), and Color Blindness [24:23].
🛡️ Part 3: Practical Eye Care & Interactive Q&A
🎯 Who Is This For?
Special Educators & Psychology Students: Professionals seeking a foundational clinical understanding of sensory processing mechanisms and impairment classifications [03:08].
Parents & Caregivers: Individuals interested in learning how sensory systems operate and how to identify early signs of visual and auditory difficulties [03:17].
