Sep 23, 2024 · Sight, hearing, touch, taste, and smell are the five senses that enable us to understand our surroundings through different types of sensory input.
- Touch. Touch is thought to be the first sense that humans develop, according to the Stanford Encyclopedia of Philosophy. Touch consists of several distinct sensations communicated to the brain through specialized neurons in the skin.
- Sight. Sight, or perceiving things through the eyes, is a complex process. First, light reflects off an object to the eye. The transparent outer layer of the eye called the cornea bends the light that passes through the hole of the pupil.
- Hearing. This sense works via the complex labyrinth that is the human ear. Sound is funneled through the external ear and piped into the external auditory canal.
- Smell. Humans may be able to smell over 1 trillion scents, according to researchers. They do this with the olfactory cleft, which is found on the roof of the nasal cavity, next to the "smelling" part of the brain, the olfactory bulb and fossa.

Your senses connect you to your environment. With information gathered by your senses, you can learn and make more informed decisions. Bitter taste, for example, can alert you to potentially harmful foods. Chirps and tweets from birds tell you trees and water are likely close. Sensations are collected by sensory organs and interpreted in the brain....
There are five basic senses perceived by the body. They are hearing, touch, sight, taste, and smell. Each of these senses is a tool your brain uses to build a clear picture of your world. Your brain relies on your sensory organs to collect sensory information. The organs involved in your five senses are: 1. Ears (hearing) 2. Skin and hair (touch) 3...
It’s rare that your brain makes decisions based on the information from a single sense. Your fives senses work together to paint a complete picture of your environment. You can see this principle in action the next time you take a walk outside. Reflect on how you feel when you’re out walking. Take note of all the different sensations you experience...
Sometimes people experience decreased sensation or the absence of a sense altogether. If this affects you, know you’re not alone. There are many people that experience life just like you do. Examples include the loss of sight or hearing. Blindness or deafness can begin at birth or be developed later in life. It does not affect everyone in the same ...
Your senses add variety and texture to your life. And it’s important to protect their health. It’s perfectly normal to experience some decline in sensation with age. But there are steps you can take to preserve your senses and take care of your body, too. Here are four important tips: 1. Be cautious with your hearing. Long-term exposure to loud noi...

Learn how your ears, skin, eyes, tongue, and nose collect and interpret sensory information from your environment. Discover the science behind hearing, touch, sight, taste, and smell, and how they connect you to the world.
- The Eyes Translate Light into Image Signals for the Brain to Process. The eyes sit in the orbits of the skull, protected by bone and fat. The white part of the eye is the sclera.
- The Ear Uses Bones and Fluid to Transform Sound Waves into Sound Signals. Music, laughter, car honks — all reach the ears as sound waves in the air. The outer ear funnels the waves down the ear canal (the external acoustic meatus) to the tympanic membrane (the “ear drum”).
- Specialized Receptors in the Skin Send Touch Signals to the Brain. Skin consists of three major tissue layers: the outer epidermis, middle dermis, and inner hypodermis.
- Olfaction: Chemicals in the Air Stimulate Signals the Brain Interprets as Smells. The sense of smell is called olfaction. It starts with specialized nerve receptors located on hairlike cilia in the epithelium at the top of the nasal cavity.
- Sight. The sense of vision is one of the strongest senses because we tend to believe more in what we see around us. The eyeball sits in the skull’s orbits, protected by bones and fat.
- Hearing. Hair cells in the ear move in response to specific sound frequencies and allow you to hear things. Music, laughter, and alarm bell all reach the ears as sound waves in the air.
- Touch. Your skin is the primary sensory organ because it covers the whole body and is directly exposed to the environment. Your skin forms the first line of defence when you experience any sort of physical or chemical stress.
- Smell. The sense of smell or olfaction gives the brain information about the odour perceived. Olfactory receptor cells in the nose detect odorants in the surrounding.
