Chemoreceptor. Chemoreceptors are sensors that detect changes in CO2, O2, and pH, and have been classified, based upon anatomical location, as either central or peripheral.

chemoreceptor a RECEPTOR that is stimulated by contact with molecules and is capable of reacting to and differentiating between different chemical stimuli. Chemoreceptors are found where external stimuli are being sampled, for example in the taste buds and in the mucous membranes of the nose Chemoreceptors. One way in which breathing is controlled is through feedback by chemoreceptors. There are two kinds of respiratory chemoreceptors: arterial chemoreceptors, which monitor and respond to changes in the partial pressure of oxygen and carbon dioxide in the arterial blood, and central chemoreceptors in the brain, which respond to changes. Chemoreceptors are stimulated by a change in the chemical composition of their immediate environment. There are many types of chemoreceptor spread throughout the body which help to control different processes including taste, smell and breathing Chemoreceptors are Group IV afferents which are sensitive not only to acid metabolites in muscles but also to prostaglandins and bradykinin.

Chemoreceptors: receptors found on sensory organs that interact with chemicals ; Ligands: the specific molecules detected by chemoreceptors ; Olfactory bulb: an organ in the nose with. Peripheral chemoreceptors are so named because they are sensory extensions of the peripheral nervous system into blood vessels where they detect changes in chemical concentrations. As transducers of patterns of variability in the surrounding environment, carotid and aortic bodies count as chemosensors in a similar way as taste buds and photoreceptors. However, because carotid and aortic bodies detect variation within the body's internal organs, they are considered interoceptors. Taste buds.

The ability of animals to distinguish such a large number of different, complex, natural chemical stimuli resides in the ability of higher centers in the nervous system to recognize. The peripheral chemoreceptor came to the rescue. Its sensitivity to P(O2) is increased which continues to drive ventilation further during acclimatization at high altitude even when pH is alkaline. This link of CO2 through the O2 chemoreceptor is described in Section 4 which led to hypoxia-inducible factor (HIF-1) A chemoreceptor, also known as chemosensor, is a sensory receptor that transduces a chemical signal into an action potential. The action potential is sent along nerve pathways to parts of the brain, which are the integrating centers for this type of feedback

The purpose of this study was to determine whether the level of arterial pressure and degree of baroreceptor activation affect responses to stimulation of chemoreceptors. Chemoreceptors were stimulated by injecting nicotine into the common carotid artery of anesthetized and paralyzed dogs. Responses Generally, a chemoreceptor will detect just a single chemical or a small range of structurally similar chemicals. Detection elicits a series of biochemical changes inside the receptor cell. The response of the receptor cell may signal yet other cells in multicellular organisms such as animals or cause a response unique to the sensing cell *Response times vary by subject and question complexity.

An increase in arterial PCO2 causes a rise in the H+. Insect mechanoreceptors can be found almost anywhere on the surface of an insect's body. They may act as tactile receptors, detecting movement of objects in the environment, or they may provide proprioceptive cues (sensory input about the position or orientation of the body and its appendages)
