Explain with diagram ?arrow_forwardExplain the mechanism for taste. Taste buds are the special organs of taste (fig. 10.5). The 10,000 or so taste buds are located mostly on the surface of the tongue and are associated with tiny elevations called papillae. About 1,000 taste buds are scattered in the roof of the mouth and walls of the throatarrow_forward
- Which of the following statements about sensory systems is NOT true? a. Sensory transduction involves the conversion (by either a direct or indirect mechanism) of a physical or chemical stimulus into changes in membrane potential difference. b. Sensory adaptation plays a role in the ability of organisms to discriminate between important and unimportant information. c. The term "sensory adaptation" refers to the process by which a sensory cell becomes less sensitive, or less responsive, to a continuing source of stimulation. d. In general, a stimulus causes a change in the flow of charged ions across the plasma membrane of a sensory receptor cell. e. The more intense a stimulus is, the greater the peak depolarization of the action potentials fired by the sensory neuron.arrow_forwardList the five major tastants.
