Mechanoreceptors

Mechanoreception is the ability to perceive mechanical stimuli with the help of special receptor cells located in various organs and tissues. These receptors perceive various mechanical stimuli, such as pressure, stretching, vibration, movement, etc.

Mechanoreceptors are widely distributed in humans and animals. They are found in the skin, muscles, joints, internal organs, nervous system and other tissues. For example, in the skin, mechanoreceptors are located in the hair follicles as well as on the surface of the skin. In muscles, mechanoreceptors are found in tendons, fascia and muscle fibers.

When a mechanoreceptor is subjected to mechanical stress, it sends nerve impulses to the brain, where they are interpreted as signals about what is happening in the environment. Thus, mechanoreception plays an important role in our ability to sense and respond to our environment.

There are several types of mechanoreceptors, each of which has its own unique properties. For example, batianesthesin mechanoreceptors are highly sensitive to pressure, and pressure mechanoreceptors, on the contrary, are sensitive to changes in pressure.

In addition, mechanoreception also plays an important role in the processes of perception of pain and sensations in the organs and tissues of the body. When mechanoreceptors become damaged or stop working, it can lead to various diseases and organ dysfunctions.

Overall, mechanoreceptives are an important part of our physiology and play an important role in our interaction with the environment and our health.

Mechanical receptors in the human body

Mechanical receptors are special cells that are located on the surface of the skin, muscles, joints and internal organs. They help the body receive information about what is happening around them and respond to mechanical stimuli such as touch, pressure, vibration and movement.

There are several types of mechanoreceptors (there are more than 50 types in total):

- thermoreceptors, take part in the formation of sensations about the ambient temperature; - pain receptors, register strong and short-term irritations, usually occur when body tissues are damaged; - nociceptors are located in the skin and ligaments. Their function is to quickly transmit a signal about damage to nerve endings or nerves. Their sensitivity to the action of a stimulus (painful) is very high; - vibration receptors perceive light tapping, pinching, light stroking, movements in the joints; - tactile, contact receptors distinguish many touches with varying degrees of pressure, distinguishes five gradations of pressure, 3 types of roughness, the shape and size of the surface of objects from the size of a circle with a diameter of 0.3 to 25 mm. There is another approach to describing the types of sensitive flasks
