Concept explainers
Introduction:
A sensory receptor converts energy from one form to another. It is involved in the conversion of various forms of stimulus energy, including sound, light, heat, vibration, and touch into nerve signals. Receptors can be classified into three categories based on the stimulus origin, modality, and its location in the body. Based on the modality of the stimulus, receptors can be classified into thermo receptors, photoreceptors, nociceptors, chemoreceptors, and mechanoreceptors. Based on the stimulus origin, receptors can be classified into exteroceptors, interoceptors, and proprioceptors.

- Name two senses that depend on chemoreceptors and describe their functions, including the specific organs and structures where the chemoreceptors are located.arrow_forwardDefine chemoreceptor reflexarrow_forwardYou have both peripheral chemoreceptors (aortic arch and carotid bodies) and central chemoreceptors (medulla). You were informed earlier that the central chemoreceptors are the primary sensors for blood CO2. Both sets of chemoreceptors detect the concentration of H+ in blood or cerebral spinal fluid (CSF). Why do the central chemoreceptors detect blood PCO2 levels while the peripheral chemoreceptors are only sensitive to total blood H+ concentration?arrow_forward
- Compare and contrast the functions of the chemoreceptorson the tongue and in the nasal cavity.arrow_forwardParasympathethic stimulation of the lungs causes  bronchi to dilate bronchioles to dilate bronchi to constrict bronchioles to constrictarrow_forwardExplain the function of central chemoreceptors as related to the respiratory systemarrow_forward
