The way we sense things is how we perceive the world around us, and to also make sense of it all. The sensory organs I chose to explain are the nose, tongue, and ears and how they connect to the brain for our perception.
As we inhale the scent of something, the molecules reach the receptor cells high in both nasal cavities. Then the axons from millions of these receptors carry nerve impulses directly to the olfactory bulb. The olfactory bulb is the smell center of the brain. From there, records are taken and the olfactory bulb transmits these impulses to the temporal lobes of the brain where they become experienced as smell. “This results in our ability to recognize around 10,000 different smells,” (Zou, Li, & Buck, 2005). How we taste: Taste buds are embedded in small lumps on the tongue, called papillae. When we eat, chemicals in food dissolve by the saliva and come into contact with the taste receptors within the taste buds. Then, adjacent neurons fire, and send nerve impulses to the brain’s parietal lobe where the messages of taste are perceived. How we hear: Sound waves first enter the ear and go to the eardrum and cause it to vibrate. The vibrating eardrum causes the anvil, hammer, and stirrup (bones within the ear) to strike each other and amplify the vibrations to the oval window and onto the fluid in the coiled cochlea of the inner ear. Now, the moving fluid sets the basilar membrane, inside the cochlea, moving. The Corti, on the top of the basilar, moves too.…
