Jun 10, 2024 · Here’s how it works. There are five basic human senses: touch, sight, hearing, smell and taste. The sensing organs associated with each sense send information to the brain to help us understand ...

- Taste. Taste, also known as gustation, is the ability to detect chemicals in food, minerals and dangerous substances such as poisons. This detection is performed by sensory organs on the tongue called taste buds.
- Smell. The sense of smell, or olfaction, is closely related to the sense of taste. Chemicals from food or floating in the air are sensed by olfactory receptors in the nose.
- Touch. Touch or somatosensory perception is perceived by activation in neural receptors in the skin. The main sensation comes from pressure applied to these receptors, called mechanoreceptors.
- Hearing. Hearing, also called audition, is the perception of sound. Sound is comprised of vibrations that are perceived by organs inside the ear through mechanoreceptors.

The nervous system must receive and process information about the world outside in order to react, communicate, and keep the body healthy and safe. Much of this information comes through the sensory organs: the eyes, ears, nose, tongue, and skin. Specialized cells and tissues within these organs receive raw stimuli and translate them into signals t...
Skin consists of three major tissue layers: the outer epidermis, middle dermis, and inner hypodermis. Specialized receptor cells within these layers detect tactile sensations and relay signals through peripheral nerves toward the brain. The presence and location of the different types of receptors make certain body parts more sensitive. Merkel cell...
What are all those small bumps on the top of the tongue? Theyre called papillae. Many of them, including circumvallate papillae and fungiform papillae, contain taste buds. When we eat, chemicals from food enter the papillae and reach the taste buds. These chemicals (or tastants) stimulate specialized gustatory cells inside the taste buds, activatin...
Published: March 29, 2024 at 4:00 am. How many senses does the average human have? Assuming you equate senses with their receptors, such as the retinas in your eyes and the cochlea in your ears, then the traditional answer to this question is five – seeing, hearing, touch, smell and taste. They’re called the ‘exteroceptive’ senses ...
- 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.
Oct 16, 2017 · Image by Bablekan. You wake up, but stay in bed for a moment, sensing the world around you. You feel your muscles pull as you stretch under the soft covers and slowly open your eyes. You might see light coming in through the blinds, hear a car honk outside, smell someone cooking breakfast, or taste dry toothpaste on your lips from brushing your ...
