- Senses are a collection of sensory cells or organs in the body that respond to specific physical occurrences. Senses send information collected to various parts of the brain where the data is translated and a response signal returns.
- The exact number of senses that human has is disputed due to the variation in definitions of what a ‘sense’ is. But, it is widely agreed that there are five main human senses: sight, hearing, taste, touch and smell.
- The 5 main sense organs are your eyes, ears, nose, tongue and skin.
- Sight or vision is the capacity of the eye to detect and focus on images with visible light with the help of photoreceptors in the retina of the eye. Electrical nerve impulses are produced for different colors and hues and brightness.
- The two types of photoreceptors are rods and cones. Rods are sensitive to light, while cones dentify colors. It is generally agreed that these two receptors are two senses, one sense for color and one for brightness, which in a combination make up the overall sense of sight.
- Hearing detects the vibrations of sound.Mechanoreceptors in the inner ear are the tiny bones and hair-like fibers, which turn sound waves from the air into electrical nerve pulses that the brain interprets.
- The sense of touch is stimulated by neural receptors like hair follicles found in the skin, but also pressure receptors on tongue and throat.
- The taste of food, is detected by taste buds on top of the tongue.
- Smell, like taste, is owed to be a chemical sense. There are hundreds of olfactory receptors or sensory cells in our nasal passage, each of which will bind itself to a different molecular smell feature.
- About 80% of what we think is taste is but smell. Flavor, is combination of taste and smell.
- Other perceived human senses are debatable but includes the ability to detect temperature, balance, pain and kinaesthetic.
- There are many internal body stimuli that might be perceived as senses too. For instance, chemoreceptors for detecting salt and concentrations of carbon dioxide concentrations in the blood and stretch receptors in the lungs which control our breathing rate.
- In comparison to animals, humans have a weak sense of smell.
- Dogs and sharks have an amazing sense of smell. While cats can see quite well under dim light.
- Some animals have receptors in spots which seem very unusual to us. Some flies and insects have taste organs on their feet, such that they can taste anything they land on and catfish have taste organs along their entire body.
- Other animals have sense receptors that we can never dream about. Some snakes have sense organs that can detect infrared light, birds and bees can see UV lights. While bats and dolphins use sonar sounds to interpret surroundings.
- Certain fishes and rays can detect changes in electrical fields near to them and many bird species use Earth’s magnetic field to determine the direction of flight.
