TADS:0000549 TADS:0000549 The adult sensory system consists of the variety of sensory ogans, or sensilla, the detect chemical compounds (e.g., odors, taste), contact with objects or surfaces, light or shadows, temperature and humidty changes. They are classified by structure or function, or a combination of the two. For the purposes of this anatomical ontology, they will be characterized primarily by structureand secondarily by function. Examples include the setiform olfactosensilla in the Haller's organ, setiform mechanosensilla all over the body, capitulum and legs, thigmotactic sensilla in the integument, or the photosensilla in the eye. Many of these sensory organs are multifunctional, e.g., combined mechanochemosensory sensilla. Many sensilla are dispersed all over the body, capitulum and legs. Others are clustered in specialized organs such as the Haller's organ on the foreleg tarsi or the sensory field on the tip of the terminal segment of the palps (palpal article IV). default_namespace anatomical cluster
