May 10, 2020 · In reptiles, birds, and mammals the taste receptors (taste buds) are found mainly to the upper surface of the tongue. They consist of pits containing sensory cells arranged rather like the segments of an orange (see diagram 15.3). Each receptor cell has a tiny “hair” that projects into the saliva to sense the chemicals dissolved in it. Sensory receptors provide information about the quality of the stimuli that they detect, giving rise to what philosophers call the qualia of conscious perceptual experience.The sensory receptors involved in taste and smell contain receptor molecules that bind to specific chemicals. Odor receptors in olfactory receptor neurons, for example, are activated by interacting with molecular structures on the odor molecule.

  1. A receptor is a group, or cluster, of nerve cells that react to a particular stimulus and receive information. Sensory receptors make up the most familiar sense organs, such as the ears and eyes. These receptors can be classified according to the type of energy or stimulus to which they respond.
  2. A tonic receptor is a sensory receptor that adapts slowly to a stimulus and continues to produce action potentials over the duration of the stimulus. In this way it conveys information about the duration of the stimulus. Some tonic receptors are permanently active and indicate a background level. Sensory Information Must Be Converted into Neural Impulses Sound, light, etc. cannot travel through our nerves to the brain. Sensory organs convert their physical properties into neural impulses.

  10. Adrenergic receptors have two main types, namely, alpha and beta receptors. Both of these receptors help regulate our fight-and-flight response when we are exposed to certain stressors. Alpha receptors and beta receptors are both located postsynaptically at the sympathetic junctions of several organs. Traditionally, the two schools of thought among pain researchers were: that the viscera are innervated by separate classes of sensory receptors, some concerned with autonomic regulation and some concerned with sensation, including pain; or that internal organs are innervated by a single and homogeneous class of sensory receptors that at low frequencies of activation send normal regulatory signals and at high frequencies of activation, induced by intense stimuli, signal pain.
