MEMBRANE POTENTIAL1
Answer a:
The stimulating condition of the cell membrane can have multiple variations.
Therefore, these variations are all in the membrane potential. The distribution of multiple
charges crosswise the cell membrane is referred to as potential. It is generally measured in
millivolts and denoted as mV (Zorova et al., 2018). The pattern is to contrast the inside of the
cell relative to the outside environments. Therefore, it can be concluded that membrane
potential is the representative value of the charge on the membrane with respect to their
surroundings.
Answer b:
The resting membrane potential can be determined by the irregular distribution of ions
(charged particles) between inside as well as outside of the cell. The resting potential is the
inequity of the electrical charge that occurs between the internal of electrically excitable
neurons along with their surroundings. The ranges in resting potential membrane lie within
the ranges of -60 to -80 mv, where the inside cell is negatively charged (Sakamuru, Attene-
Ramos & Xia, 2016). Here the cell is in the resting position. If that cell becomes more
electronegative then the membrane will be called hyperpolarized.
Answer c:
According to Levitan & Kaczmarek (2015), for initiation of an action potential, the
threshold level should be in such a way that membrane potential can be depolarised. In the
threshold level, if the neuron does not reach that critical level then there would not be any
action potential. Therefore, it is crucial for regulation as well as propagating the signals. Both
the resting membrane as well as threshold potential maintained the balances.
