- describe how the membrane potential varies over time AND distance as a graded potential move across the cell body of a neuron. Describe the movement of ions within the cell body as the graded potential moves away from the stimulusIf a stimulus produces a receptor in a receptor cell capable of producing action potentials does that faire tee that the stimulus will always be encoded by the receptor cell and a signal be passed on to the second order neuron? Explain the mechanisms in detail.Define receptor potential
- Characterize each receptor activity described below by choosing the appropriate letter and number(s) from keys A and B.Describe the following terms: specificity, stimulus, receptor potential, synapse, neurotransmitter, graded potential, an action potential?In terms of a gated channel what is the difference between a threshold stimulus and a sub threshold stimulus?
- Receptors such as those in the inner ear, respond to stimulation with an AM response. In contrast, a neuron connected to that receptor, sending information centrally (ex: the brain) respond in an FM manner. Differentiate between: I. how the degree of stimulation to the receptor is encoded as compared to, II. the degree of the stimulation encoding by the neuron connected to the receptorA specific stimulus produces a receptor potential by :-a- inhibiting Na + influx into receptorb- inhibiting K + efflux from receptorc- enhancing Na + influx into receptord- enhancing K + efflux from receptorApplying a pressure stimulus to the fluid-filled capsule of an isolated Pacinian corpuscle causes a brief burst of action potentials in the afferent neuron, which ceases until the pressure is removed, at which time another brief burst of action potentials occurs. If an experimenter removes the capsule and applies pressure directly to the afferent neuron ending, action potentials are continuously fired during the stimulus. Explain these results in the context ofadaptation.
