Document Summary
Signal transduction involves: conversation of stimulus to an electrical signal. The pleasant scents of roses are detected by chemoreceptors. Pain receptors are triggered when stimuli become too extreme for thermoreceptors. Photoreceptors are found in your eyes; while chemoreceptors are found in your nose and mouth. A stimulus is information from the environment that is converted to a sensory signal in the body. A sensory receptor is a cell that is capable of detecting stimuli and communicating this information to the central nervous system. Sensory transduction is the conversation of an environmental stimulus (such as light energy) to an electrical communication signal within the body. A signal transduction pathway is a series of proteins within a cell that passes a signal along from one molecule to another until a final reaction occurs. Sensory adaptation is the tendency for repeated stimuli to become less noticed over time. A receptor cell detects a stimulus (signal) and converts it to an electrical signal.
