What is a generator potential (also known as a receptor potential)?Group of answer choicesthe potential at which a sensory stimulus has no effect on a sensory neuronthe potential which blocks action potential production in a sensory neuron activated by its adequate stimulusthe change in membrane potential generated in the post-synaptic neuron which a sensory neuron synapses with in the CNSthe potential evoked by the stimulus which drives the action potential firing in a sensory nerve terminalthe potential at which action potentials are inhibited in a sensory neuron PreviousNext

A depolarization that happens in a sensory receptor on stimulation is known as a potential.

Receptor potential initiated by an adequate stimulus:- a- develops always at it full magnitudesb- undergoes temporal summation onlyc- undergoes spatial summation onlyd- could initiate an action potential

Describe the events involved in the generation and propagation of an action potential.

Which of the following describes a change from the resting membrane potential?an action potentiala receptor potential, a synaptic potential or an action potentiala receptor potentiala synaptic potential

3. List the steps involved in the generation of an action potentialin a sensory nerve fiber beginning with the stimulation of aPacinian corpuscle.A. Light touch is applied to the Pacinian corpuscle, and areceptor potential is generated; as the pressure is increased,the size of the receptor potential is increased; when itreaches 30 mV, an action potential is produced at a point ofthe sensory nerve within the corpuscle.B. Light touch is applied to the Pacinian corpuscle, and areceptor potential is generated; as more receptors arebrought into the receptive field, the size of the receptorpotential increases; when it reaches 30 mV, an actionpotential is produced at the first node of Ranvier.C. Sustained pressure is applied to the Pacinian corpuscle,and a receptor potential is generated; as more receptors areactivated, the size of the receptor potential increases; whenit reaches 10 mV, an action potential is produced at the firstnode of Ranvier.D. Rapid vibration is applied to the Pacinian corpuscle, and agraded receptor potential is generated; when the receptorpotential reaches 10 mV, an action potential is produced atthe first node of Ranvier.E. Rapid vibration is applied to the Pacinian corpuscle, and areceptor potential is generated; when the receptor potentialreaches 10 mV, an action potential is produced in theunmyelinated portion of the sensory fibe
