(PDF) Effect of Cardioactive Drugs on Action Potential
The two ions mainly involved in establishing a resting potential (and generation of action potentials) are K + and Na +. Imbalances in the concentrations of these ions either side of the plasma membrane are created by the operation of an ionic ‘pump’ located in the membrane. This is the Na... An action potential is a wave of electrical discharge that travels along the membrane of a cell. Action potentials are an essential feature of animal life, rapidly carrying information within and between tissues.

Modelling Action Potential Generation and Propagation in

The action potential is a propagating voltage pulse traveling along the nerve axon. Since the first description of its electrical features by Luigi Galvani [1] and Volta [2] in the past decade of the eighteenth century, its nature has been in the focus of intense studies during the recent 200 years. Starting from a famous paper by Bernstein [3] in 1902, it has been assumed that the...
5) Refractoriness – following an action potential, there is a period of time during which a cell cannot fire another action potential. 6) Propagation without decrement – action potentials are able to propagate

2. Depolarization: Generation and propagation of an action potential. The end plate potential ignites an action potential by spreading to adjacent membrane areas … core science stage 5 filetype pdf In the study reported here, we examined the generation and propagation of action potentials in giant axons of the earthworm Lumbricus terrestris. The ventral nerve cord of this animal has one medial and two lateral giant axons. In our experiments, we placed stimulating electrodes around the nerve cord near the head of the animal and recording electrodes near the nerve cord along the length of.

The experiment found that the generation of action electrical-potential is accompanied always with the increases of shifted speed of Na ions along the direction of increase of the gradient of electrical chemical potential.

  • It is worth differentiating between the action potential and the nerve impulse. To make this differentiation might be thought of as semantic quibbling. Many types of cells can generate action potentials, for example oocytes, some gland cells, and even plant cells. Few cells have action …
  • Using a standard Hodgkin?Huxley (HH) formalism, we present a mathematical model for action potential (AP) generation and intercellular AP propagation in quiescent (serum?deprived) normal rat kidney (NRK) fibroblasts [1], based on the recent experimental identification of the ion channels involved [2].

  • It reproduces excitability of single NRK cells and cell clusters and intercellular action potential (AP) propagation in NRK cell monolayers. Excitation can be evoked by electrical stimulation, external potassium-induced depolarization, or hormone-induced intracellular calcium release. Analysis shows the roles of the various ion channels in the ultralong ( approximately 30 s) NRK cell AP and
