Sensation and Perception (Ep6+)

Question 1

Describe the process of hearing

Answer 1

• Outer ear gathers sound waves and funnels them through the ear canal into the middle ear
• Sound vibrations cause the ear drum to vibrate
• Ear drum vibrations are amplified by oscicle bones (Stirrup, Hammer, Anvil)
• vibrations travel to inner ear where they vibrate the cochlea and it’s surrounding fluids get jostled around causing some of your 16 thousand tiny cochlea hair cells to bend
• This motion triggers neighbouring nerve cells that convert that physical energy into electronic pulse zipping up the auditory nerve into the auditory cortex
• auditory cortex desciphers what the sound is

Describe the process of tasting
