WebbDuring movement, sensory receptors in muscles, joints and the skin send movement-related information to the brain where it is used for kinesthesia. For more than 30 years, it was thought that the muscle spindle, a specific type of muscle receptor, was the most important source of kinesthetic information [ 1, 3 ].
WebbThe types of sensory receptors according to location include cutaneous receptors and mechanoreceptors. Sensory receptors located in the dermis or epidermis of the skin are called cutaneous receptors. These include nociceptors and thermoreceptors.
