This occurs as the entrance of Na + depolarizes the cell, thus allowing the parallel entrance of Cl ".
12.
A radiofrequency signal is then transmitted to the implanted receiver stimulator and is later converted to an electrical stimuli that depolarizes the peripheral nerve.
13.
This so-called'dark current'depolarizes the cell to around-40 mV . Note that this is significantly more depolarized than most other neurons.
14.
The high potassium concentration in this chamber depolarizes the immersed segment of the tissue, allowing potential differences to be measured between the two segments separated by the sucrose gap.
15.
With a sufficient number of channels opening at once, the inward flow of positive charges carried by Na + ions depolarizes the postsynaptic membrane sufficiently to initiate an action potential.
16.
An influx of potassium ions depolarizes the cell and causes the release of a neurotransmitter that can initiate nerve impulses in the sensory neurons that synapse on the base of the hair cell.
17.
The axon terminal depolarizes and releases Acetylcholine ( ACh ), a neurotransmitter, which in turn stimulates the motor end plate ( MEP ) of the muscle fiber the nerve is innervating.
18.
In the dark, a photoreceptor ( rod / cone ) cell will release glutamate, which inhibits ( hyperpolarizes ) the ON bipolar cells and excites ( depolarizes ) the OFF bipolar cells.
19.
When subjected to reversed polarity ( even briefly ), the capacitor depolarizes and the dielectric oxide layer breaks down, which can cause it to fail even when later operated with correct polarity.
20.
In the process of binding, decamethonium actually activates ( depolarizes ) the motor endplate-but since the decamethonium itself is not degraded, the membrane remains depolarized and unresponsive to normal acetylcholine release.
