  1. Unique Characteristics of the Five Human Senses Webster's Dictionary defines the word sense as the faculty of perceiving something physical. So when you think of the five human senses, a classification attributed to the late Aristotle, you are reminded of those five fabulous sensations that allow human beings to know and better understand the world around them. Those five senses are sight, hearing, taste, smell and touch. While together those senses provide human beings with a well-rounded view of the world, each of them exhibit unique characteristics that separate them from the rest.

  2. SIGHT The eye is a complex organ, making sight the most sophisticated of the five senses. When you consider the importance of eyesight in every day life, it makes sense that the human body intrinsically protects the eye. Just like the President of the United States requires protection by the Secret Service, those inconspicuous men in black, the eyes require specific, and somewhat inconspicuous, protection as well. Eyebrows, eyelashes, eyelids and tears all serve important purposes to protect the eye, keeping it clean of particles, sweat and debris.

  3. HEARING While hearing is second on the list of the most important of the five senses, it is not the only reason human beings are born with ears. Though hearing allows human beings to better perceive the world around them, ears actually serve the equally important purpose of balance. Your ear contains three canals that are filled with fluid. This fluid pushes against hair-like nerve-endings in your ear to send messages to your brain. Those messages distinguish whether you are feeling dizzy or balanced.

  4. TASTE Considered the weakest of the five senses, taste involves a chemical sense that allows human beings to distinguish the flavor of the food they eat--sweet, salty, sour and bitter. The mouth houses more than 10,000 taste buds, located on both the tongue and the roof of the mouth. When they are born, human beings also have taste buds on the sides of their mouth. However, with age, those taste-buds slowly disappear, making them less sensitive to the taste of food. A child experiences increased sensitivity to the taste of food.

  5. SMELL Smell is intrinsically linked to both the human being's mood and memory. For instance, a particular smell can take a person as far back as their childhood, forcing certain memories to the surface of their mind. And, because the nose is an essential tool in breathing, a person's sense of smell can actually lead to better moods, as well as to better health. The nose acts as a heater and filter to the air passing through to the lungs. This, ultimately, becomes vital to a person's mental and physical health.

  6. TOUCH Of the five senses, touch is the only sense that lacks a specific location. Touch originates in the bottom layer of the skin and is found all over the body. Because of the many nerve-endings that fill this bottom layer of skin, a human being can distinguish hot from cold, and pain from pleasure. Touch becomes unique because it is an invaluable part of being human. Human beings instinctively need touch, especially babies. Without the early sensation of being touched, babies in orphanages fail to thrive.

  7. Sample activity all humans are similar with the use of senses We experience everything in the material world through the lens of our five senses: sight, sound, smell, taste and touch. One of the few activities that all humans do that makes use of all five senses is eating. While you may think of food as only relating to taste, all your senses work to create an impression of a food, whether pleasant or unpleasant, unique or bland. In this experiment, you will examine the extent to which different sensory experiences create more or less lasting impressions in memory.

  8. They all contribute to us something special. And that is our senses. Changes in the surrounding are called stimuli. Our sensory organs then function as receptors and receive the stimuli. (singular: stimulus) For example, our ears detect stimuli when we hear something. The way the stimulus travels through our body is described below.

  9. Stimulus > Receptors > Nerves > Brain > Nerves > Effectors (such as muscles)> response

  10. As seen above, after our sensory organs receive the stimuli, it sends nerve impulses to the brain which then interprets it, and effectively decides what to do. It then sends nerve impulses to the related effectors (parts of the body which carry out responses according to what the brain 'says') Some examples of effectors are muscles and glands.
