Document Summary
Sensory receptor organ : an organ (such as the eye or ear) specialized to receive particular stimuli. Stimulus : a physical eventhat triggers a sensory response. Receptor cell : a specialized cell that responds to a particular energy or substancein the internal or external environment, and converts this energy into a change in the electrical potential across its membrane. Adequate stimulus : the type of stimulus for which a given sensory organ is particularly adapted. Specific nerve energies : the doctrine that the receptors and neural channels for the different senses are independent and operate in their own special ways, and can produce only one particular sensation each. Labeled lines : the concept that each nerve input to the brain reports only a particular type of information. Sensory transduction : the process in which a receptor cell converts the energy in a stimulus into a change in the electrical potential across its membrane.
