O Moving potential
O Threshold
Answer:
Resting potential
Explanation:
Glial cells are not part of the nerve impulse reaction; they provide support and insulation in the nervous system. Resting potential, action potential, and threshold are all directly involved in the nerve impulse conduction.
The component that is NOT part of the nerve impulse reaction among the given options is Glial cells. The other options, such as resting potential, moving potential (commonly referred to as action potential), and threshold, are all directly involved in the generation and propagation of a nerve impulse.
Resting potential refers to the difference in electrical charge across the plasma membrane of a neuron when it is not actively transmitting a signal. It is sustained by the sodium-potassium pump which helps maintain the distinct concentrations of sodium (Na+) and potassium (K+) ions inside and outside the cell. When the neuron is stimulated and the threshold is reached, voltage-gated Na+ channels open, causing an action potential by reversing the electrical charge across the membrane, allowing the nerve impulse to propagate along the neuron.
Glial cells, such as astrocytes and oligodendrocytes as shown in Figure 35.8, are supportive cells in the nervous system. They provide structure, nutrition, insulation, and help with signal transmission by myelinating axons, but they do not participate in the actual electrical signal or impulse that characterizes neuron communication.
