Exteroceptor

Exteroceptor (from Latin exterus - external and receptor - receiving) is a sensory nerve ending that perceives irritations from the external environment. Exteroceptors are located in the skin, mucous membranes and sensory organs such as eyes, ears, nose, tongue.

Exteroceptors include receptors for touch (tactile, temperature, pain), smell, taste, vision, hearing and balance. They respond to mechanical, temperature, chemical and light stimuli from the external environment and convert them into nerve impulses, which then enter the brain along pathways.

Thus, exteroceptors provide communication between the body and the outside world and are an important part of the sensory systems responsible for perceiving information from the environment.

Exteroceptors are sensory nerve endings that perceive irritations from the external environment and transmit them to the central nervous system. They are located in the skin, mucous membranes and sensory organs such as the eyes, ears, nose and tongue.

Exteroceptors play an important role in our lives as they allow us to sense our environment and respond to changes in it. For example, exteroceptors in the skin allow us to sense touch, pressure, and temperature. Exteroceptors on the tongue allow us to taste food. Exteroceptors, located in the eyes, ears, and nose, help us perceive sounds, smells, and sights.

In addition, exteroceptors are also involved in regulating our behavior and mood. For example, if we feel pain or discomfort, this may cause us to react with fear or aggression. If we experience pleasant sensations, such as warmth, comfort or pleasure, this can cause us positive emotions and improve our mood.

Overall, exteroceptors are an important element of our nervous system and play a key role in our interaction with the environment.

Exteroceptors are sensory nerve endings that perceive irritations from the external environment and are located in the skin and various sense organs (ear, eye, etc.).

These endings belong to the first and second types of receptors - free endings and encapsulated nerve endings. Among them, two types of free endings are distinguished. Free endings of the first type are called exteroceptive thermoreceptors, and the second type are called tactile endings. In addition, there are exteroceptive mechanical receptors and free-swimming receptor organisms.

Like other types of receptors, exteroceptors play an important role in providing sensitivity to the external environment, as well as in the processes of perception of various stimuli,
