8. Which type of sensory receptor is responsible for smell and taste? (1 point) photoreceptor thermoreceptor mechanoreceptor chemoreceptor
Weegy: chemoreceptor There are two main classes of the chemosensor: direct and distance. Examples of distance chemoreceptors are: olfactory receptor neurons in the olfactory system: Olfaction involves the ability to detect chemicals in the gaseous state. [ In vertebrates, the olfactory system detects odorants and pheromones in the nasal cavity. Within the olfactory system there are two anatomically distinct organs: the main olfactory epithelium (MOE) and the vomeronasal organ(VNO). It was initially thought that the MOE is responsible for the detection of odorants, while the VNO detects pheromones. The current view, however, is that both systems can detect odorants and pheromones.[1] Olfaction in invertebrates differs from olfaction in vertebrates. For example, in insects, olfactory sensilla are present on their antennae.[2] Examples of direct chemoreceptors include: Taste buds in the gustatory system: The primary use of gustation as a type of chemoreception is for the detection of tasteants. Aqueous chemical compounds come into contact with chemoreceptors in the mouth, such as taste buds on the tongue, and trigger responses. These chemical compounds can either trigger an appetitive response for nutrients, or a defensive response against toxins depending on which receptors fire. Fish and crustaceans, who are constantly in an aqueous environment, use their gustatory system to identify certain chemicals in the mixture for the purpose of localization and ingestion of food. Insects use contact chemoreception to recognize certain chemicals such as cuticular hydrocarbons and chemicals specific to host plants. Contact chemoreception is more commonly seen in insects but is also involved in the mating behavior of some vertebrates. The contact chemoreceptor is specific to one type of chemical. Olfaction: In vertebrates, olfaction occurs in the Nose. Volatile chemical stimuli enter the nose and eventually reach the olfactory cleft (where the main olfactory epithelium is ... (More)
