Have answered some questions but needed help with

why the resting membrane potential the same value in both the sensory neuron and the Interneuron?

and

Identify type of membrane potential (graded receptor potential or action potential) that occurred at R1, R2, R3 and R4 when moderat stimulus is applied.

56.Describe what happened when you applied a very weak stimulus to the sensory receptor, i.e. was there an action potential?  How many vesicles were released?

NO RESPONSE AT R3 BECAUSE THE VERY WEAK STIMULUS DOES NOT DEPOLARIZE THE AXON OF THE SENSORY NEURON THRESHOLD.

57.Describe what happened when you applied a moderate stimulus to the sensory receptor, i.e. was there an action potential?  How many vesicles were released?

4 VESICLES RELEASED.

58.Identify the type of membrane potential (graded receptor potential or action potential) that occurred at R1, R2, R3, and R4 when you applied a moderate stimulus.  (Compare/view the response to the stimulus.)

THE STIMULUS INDUCES A GRADED RECEPTOR POTENTIAL AT R1

59.Describe what happened when you applied a strong stimulus to the sensory receptor.  What type(s) of membrane potential were caused?  Were the responses at R1 through R4 all the same?

ACTION POTENTIALS GENERATED AT ALL 4 LOCATIONS
