WebDec 4, 2024 · 100. Figure 42.2.2: The (a) resting membrane potential is a result of different concentrations of Na + and K + ions inside and outside the cell. A nerve impulse causes Na + to enter the cell, resulting in (b) depolarization. At the peak action potential, K + channels open and the cell becomes (c) hyperpolarized. WebApr 6, 2024 · A nerve impulse is essentially an electrical signal that originates in a nerve cell. It moves along dendrites and produces action potential, which is typically the inward and outward flow of ions in the cell. 3. What are the Components of a Neuron. Ans. Components of neurons are – dendrite, axon, axon terminal, soma, the node of Ranvier ...

WebMar 5, 2024 · Action Potential. A nerve impulse is a sudden reversal of the electrical charge across the membrane of a resting neuron. The reversal of charge is called an action potential. It begins when the neuron receives a chemical signal from another cell. The signal causes gates in sodium ion channels to open, allowing positive sodium ions to flow back ... WebNov 29, 2024 · Definition. Neural pathways are groups of nerve fibers which carry information between the various parts of the CNS. Neural pathways that connect the CNS and spinal cord are called tracts. Ascending tracts run from the spinal cord to the brain while descending tracts run from the brain to the spinal cord.
