What is a sensory receptor?

The human nervous system relies on the sensory nerve ending to transmit information about the environment of the brain and motor neurons. The stimulation of the sensory receptor creates a chemical reaction that converts into an electrochemical impulse, which in turn travels to the brain. Sensory neurons, also called afferent neurons, also collect information from the body and pass it to the brain. The nervous system has several types of sensory receptors grouped with a type of stimulus that activates a sensory receptor known as an adequate stimulus. Sensory receptors are also grouped according to the location and speed they adapt to the stimuli. For example, photoreceptors respond to visible light and broadcast signals along the optical nerves into the occipital brain lobe. Chemoreceptors control taste and aroma, combine with specific chemicals that Attach, to the taste buds or interior of the nostril.

The skin contains receptors built in the whole that are responsible for detection of pain, pressure, temperature or humidSTI. Proprioptors found throughout the skin and muscles provide the body information about its parts in relation to each other. Liquid bags in the inner ear contain proprioptors that provide the brain information about the head position relative to the ground.

sensory receptors are placed in muscles, skin and sensory organs. Skin and subcutaneous or skin are receptors responsible for most of the surface feeling: temperature, pressure and pain. Their nerve endings are branched into the upper and lower layers of the skin.

pain receptors are missing in the brain and other internal organs. Any information is sent to the corresponding skin area via Refebolest. Mechanoreceptors can be found in the muscles. They detect the contraction or prolongation of muscle tissue so that the brain senses muscle performance.

any sensory receptor can be classified as a tonic or phase receptor, depending onat its speed adaptation to stimuli. Tonic receptors send a constant signal when activated by a stimulus and constantly shoot. For example, proprioptors are tonic because they always provide the brain information. Phase receptors remain inactive until they receive the stimulus and do not adapt quickly. Thermoreceptors, responsible for the temperature feeling, are phase receptors; The skin receives information about its temperature and quickly adjusts its basic temperature to match.
