An action potential conduction from the eye to the human brain has about 100,000 times as much energy as the light photons that triggered it. This is an example of: A Sensory adaptation. B Mechanoreception. C Nociception. D Amplification.

What event is responsible for the conversion between cis and trans configurations of retinal? - the opening of Na+ channels - activation of a G protein - the absorption of light - activation of the enzyme phosphodiesterase - adaptation Which of the five types of taste sensations is the most sensitive? - bitter - salty - sweet - umami - sour Perception is: - Receiving signals by the receptors - Transducing signals to CNS - Changing cell membrane potential - Brain construction of the stimulus In sensory adaptation: - The receptor responsiveness to the stimuli decreases - The receptor responsiveness to the stimuli increases - The receptor responsiveness to the stimuli decreases and then immediately increases - The receptor responsiveness to the stimuli does not change Pain receptors: - Do not exist in humans - Do not exist in animals - Are called nociceptors - None of the above

Initial steps of transduction of visual stimuli into electrical signals are: Light energy → rods → color vision Light energy → photoreceptors → closing of Na+ channels; hyperpolarization Light energy → photoreceptors → opening Na+ channels; depolarization Light energy → cones → high temporal resolution

A sensory receptor absorbs energy from some stimulus. The next step is (a) release of neurotransmitter (b) transmission of an action potential (c) energy transduction (d) transmission of a receptor potential (e) sensory adaptation
