What are the senses?

A person receives various information aboutthe environment and the state of one's own body with the help of the senses. All sensory organs have their receptors (sensory nerves), the signal from which is transmitted to the central nervous system. Thanks to this, a person can react to everything that happens in the world around him. In this article, Elhau will tell you about the senses.

Sense organs

  • Eyes
  • Ears
  • Skin Receptors
  • Nose
  • Language

What are the senses, you now know, but you should consider each of them in more detail, as well as the feelings that we feel through it.

Eyes

This sense organ enters the visual systemman, thanks to which we have sight, that is, we see the world around us, as an image of objects and their location in space. Eyes refer to distant senses, that is, sensory organs that react to irritation at a distance.

Ears

This body belongs to distant sensory organs and performs two functions:

  • Perception of sounds. The human ear can perceive not all sounds, but only sound waves located in the range 16-20,000 Hz.
  • A sense of balance and the position of the body in space. This feeling is called - equibrioception, and is provided by the vestibular apparatus (part of the inner ear).

Skin Receptors

Skin covers a lot of functions, including sensitive ones:

  • Thermoreception is a feeling of warmth and lack of it. It is due to the receptors of the skin that we feel the heat or cold, the temperature of various objects.
  • Touch or tactile feeling. Thanks to the skin, we can feel the touch, their strength, vibration, texture of objects (for example, smoothness, roughness and so on).

This sense organ reacts to irritation only with direct contact, in contrast to distant sensory organs.

Nose

Thanks to this sense ofto distinguish smells, this feeling is called sense of smell. It is worth noting that the person has the best sense of smell at birth, with age, the ability to distinguish smells is deteriorating. In addition, scientists argue that the sensitivity to odors in women is higher than that of men.

Language

Thanks to this sensory organ, a person can distinguish between the taste of different substances. However, the language also has tactile receptors, that is, it is capable of transmitting the temperature and texture of substances.

Now you know what the human senses, but in addition to these types of sensations obtained with the help of these senses, the person has other feelings:

  • feeling of pain (perceived by the skin, organs and joints).
  • proprioception - a sense of position in space,movement and strength (the feeling of one's own body). Proprioceptors are located in the muscles, joints, tendons, and allow us to understand how our limbs are positioned relative to our body. Thanks to the work of the receptors, we can regulate the strength of our actions, as well as determine whether we are at rest or moving.
