Title: physioex 9 review sheet neurophysiology of nerve impulses activity 9 Post by: dacaol on Nov 7, 2011 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.

Title: Re: physioex 9 review sheet neurophysiology of nerve impulses activity 9 Post by: Hollow on Dec 1, 2011 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 Title: Re: physioex 9 review sheet neurophysiology of nerve impulses activity 9 Post by: agmc2010 on Jan 29, 2012 Thanks needed help with this also :)

Title: Re: physioex 9 review sheet neurophysiology of nerve impulses activity 9 Post by: kanos on Apr 11, 2012 why the resting membrane potential the same value in both the sensory neuron and the Interneuron? I have been looking for the same answer.
