The five senses are the five main tools used by people to perceive the world. These senses are vision, smell, hearing, taste, and touch. We see with our own eyes, we smell our nose, listen with our ears, taste the language and touch the skin. Our brain receives signals from each organ and interprets them to give us a sense of what is happening around us. Read below sense organs functions.


sense organs functions


 The eyes allow us to see. But if you break them, they do more than just that. Using our eyes, we can assess the depth, interpret new information and identify colors (wavelengths reflecting off the surface).


Noses use to smell odors. They give you a sense of what particles are moving in the air, which can help us determine if there are dangerous chemicals in the vicinity. The fragrance also has the strongest connection to the memory; a familiar smell can remind us of things long forgotten.


The ears let us hear the sound – detect the vibrations in the air particles surrounding us. But the internal ear also helps us preserve balance and regulate sinus pressure. This is especially useful when changing altitude (for example when flying in an airplane).


Languages are used to taste the food, allowing us to find out if something will be useful to our body or poisonous. They also allow us to feel the heat and cold in food and drink.


The last of all is skin, which is responsible for what can be the most important sense in the human body. The skin meets a huge number of functions. They include:

Sweating (sweating) to cool the body
Protection from the elements


Other internal sense organs functions


The inner sense also known as interception is “any sense normally stimulated from within the body”. They include numerous sensory receptors in internal organs, such as stretch receptors that neurologically associate with the brain. Interoception is thought to be atypical in clinical settings such as alexithymia.  Some examples of specific receptors are:


Hunger is an impression that regulates with a set of brain structures (such as the Hippola) responsible for energy homeostasis.
Pulmonary tensile receptors are located in the lungs and control the respiratory rate.

Peripheral brain chemoreceptors monitor levels of carbon dioxide and oxygen in the brain to induce strangulation when levels of carbon dioxide are too high. 

The resting area of the chemoreceptor is the area of the brain’s core that receives input from blood-derived medicines or hormones and communicates with the center of vomiting.

Chemoreceptors in the circulatory system also measure salt levels and speed up thirst if they are too high; they can also respond to high blood sugar in patients with diabetes.

Skin receptors in the skin not only react to touch, pressure, temperature, and vibration, but also react to the expansion of blood vessels in the skin, such as blushing.

Stretch receptors

Stretch receptors in the gas stretching of the gastrointestinal tract, which can cause colic pain.
Stimulation of the sensory receptors in the esophagus results in sensations experienced in the throat during swallowing, vomiting or during gastric reflux.

Sensory receptors in the mucous membrane of the throat, similar to the tactile receptors in the skin, sense foreign objects, such as food, which can cause the gag reflex and the corresponding sense of leaven.

Stimulation of the sensory receptors in the bladder and rectum can cause a feeling of fullness.
Stimulation of traction sensors that sense the dilation of various blood vessels can cause pain, for example, a headache caused by vasodilation in the arteries of the brain. Cardioversion refers to the perception of heart activity. Opsin and direct DNA damage in melanocytes and keratinocytes can detect ultraviolet radiation, which plays a role in pigmentation and sunburn.
