Science still doesn't agree on how many senses a person actually has. The fact is that there are at least 5, but there are probably many more. For now, however, I'm going to talk to you about the 5 classic and most famous.

Our senses

Seeing, visual perception, visual perception

Is the processing of (visual) stimuli in the brain that were detected by the eye. The eye perceives and sends stimuli to the brain for easy explanation. In the brain, there are then colors, shapes, depths, sharpness,. shaped and that gives us the image we see.

Hearing, hearing, sound perception

Is an organism's ability to perceive sounds, often direction-sensitive to the sound source. Hearing works by means of an ear, the auditory organ where sound waves are converted into action potentials in the auditory nerves.

Smell, sense of smell, sense of smell

Is a neurological processing in the nasal cavity, the actual awareness of perception, takes place in the brain. The molecular fragrance binds to the ciliated epithelium in the nose at a specific receptor. The receptor stimulates mitre cells and this signal eventually reaches the brain via nerve tracts. Odours can be seen in the air but also in other gases or gas mixtures, sometimes even in water. So when we smell a smell with our nose, this is actually not a property of a substance, just an interaction between a substance and an observing organism.

Tasting, sense of taste, oral perception

Is the ability of an organism to perceive certain compounds directly as flavors. This is also called gustative ability. The organ where most taste receptors are located is the tongue, but there are also taste receptors at the back of the oral cavity. Sweet, sour, bitter, salty and umami are the basic flavors that we can observe.
