What is the resting potential? What are the charges inside and outside of the neuron? Which ions are found in and outside of the neuron? When the neuron is at a resting potential, is it polarized, depolarized, repolarized

Expert Solution

1.Resting membrane potential is potential in membrane at rest where no transmition takes place

Here RMP is -70 mv ..

I gave the name of each phase and cause of each ie ionic basis of each ..

To transmit signal membrane should be depolarize.

Hence to depolarize Na+ channels opens ...

Make inside cell fill with more positive charge .. to nullify the negative charge ...and potential goes towards zero .

As soon as potential reaches to -55mv which is thresothr for action potential ...

It shoots .. more Na+ channel opens .. rapid shoot ( phase1) occurs ...

.as soon as it near to zero / more than zero ... The Na+ channel closes and potassium channel opens ... It's happen due to voltage gated channel( at specific voltage channels opens / closes)

Now potassium channel opens and k+ is rapidly move out of cell membrane and potential drops ...rr repolarization ( phase2)

But due to delayed in closure of k+ channel more negative become potential this phase3 (hyperpolarizatio).

After phase 3 ... The Na+ k+ pump active and make balance between ion and again membrane potential become as resting membrane potential..(-70mv)

Ready to receive another stimulus..

Describe the resting membrane potential and the forces at play in a resting neuron concisely, but thoroughly

Describe the resting membrane potential and the forces at play in a resting neuron concisely, but thoroughly. At minimum, the following terms/concepts should be explained in your response: membrane potential, ion channels (and the two main ions involved, and their relative distribution), the two types of forces/pressures acting on each of the ions, and the special transporter of these two ions (and what it does). Here is a previous answer I got(it was great!)- please build off it though, and...
