"WebYour answer is correct. If only neuron y is fired, hyperpolarization will occur. Neuron x initiates an action potential and causes depolarization. Neuron y on the other hand causes repolarization until it reaches resting membrane potential. If only neuron y is fired, then it will further cause repolarization which is termed as hyperpolarization. " - Resting membrane potential of neurons

WebFigure 16.11. The formation of an action potential can be divided into five steps: (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached, all Na+ channels open and the membrane depolarizes. WebExplanation: A membrane potential of -70 mV is present in neurons. However this phenomena is not specific to neurons, membrane potential exists in other types of cells as well from anywhere between -15 to -100 mV. 7. ... the potential difference that exists between extracellular and intracellular environments is termed as resting potential.
