exteroceptor noun[ C ] anatomy specializeduk /ˌek.ster.əʊˈsep.tər/ us /ˌek.stɚ.ə.rɪˈsep.tɚ/ a sense organ or part of the body, such as the eye or the ear, that reacts to information or changes from outside the body : Body-awareness is determined by exteroceptors: touch, taste, smell, sound, and sight. After receiving an external stimulus, the exteroceptor converts it to a nerve impulse and sends it to the central nervous system. Intense anxiety can diminish the exteroceptors to the extent that perception of the outside world becomes seriously distorted. Both exteroceptors and interoceptors find their particular expression in the hands and significantly contribute to what is called haptic perception.
