Exploring Senses: Vision, Hearing, Balance, Smell, Taste & Touch

Dive into the workings of the nervous system with a focus on the senses - vision, hearing, balance, smell, taste, and touch. Understand how your eyes respond to light, how sound is processed in your ears, and how taste and smell are closely connected. Uncover the structures within your body that control these sensory experiences and learn about correcting vision issues like nearsightedness and farsightedness.

  1. Ch.19 The Nervous System Section 3: The Senses

  2. Section 3 • Vision • Your eyes respond to the stimulus of light. They convert that stimulus into impulses that your brain interprets, enabling you to see • How Light Enters Your Eye • Cornea • Pupil • Iris • How Light is Focused • Lens

  3. Section 3 • Vision • How You See an Image • Retina • Correcting Nearsightedness

  4. Section 3 • Vision • Correcting Farsightedness • What type of lens corrects nearsightedness?

  5. Section 3 • Hearing & Balance • Your ears are the sense organs that respond to the stimulus of sound. The ears convert the sound to nerve impulses that your brain interprets. • How Sound is Produced • The Outer Ear

  6. Section 3 • Hearing & Balance • The Middle Ear • Eardrum • The Inner Ear • Cochlea

  7. Section 3 • Hearing & Balance • The Inner Ear & Balance • Structures in your inner ear control your sense of balance • Semicircular canals • Where in the ear are the semicircular canals located?

  8. Section 3 • Smell & Taste • The sense of smell and taste work closely together. Both depend on chemicals in food or in the air. The chemicals trigger response in receptors in the nose and mouth • What basic tastes can the tongue detect?

  9. Section 3 • Touch • Your skin contains different kinds of touch receptors that respond to a number of stimuli
