Electrotonus is a term used in physiology to describe the changes in electrical excitability in a nerve or muscle cell in response to the application of an electric current. It plays a crucial role in understanding how nerve cells communicate with each other and how muscle cells contract.
Types of Electrotonus
There are two main types of electrotonus: anodal and cathodal. Anodal electrotonus refers to the increase in excitability of the nerve or muscle cell when a positive current is applied, while cathodal electrotonus describes the decrease in excitability when a negative current is applied. These changes in excitability are essential for the proper functioning of the nervous system.
Characteristics of Electrotonus
Electrotonus is characterized by two main properties: subthreshold depolarization and hyperpolarization. Subthreshold depolarization occurs when the membrane potential of the cell becomes less negative, making it easier for the cell to reach its threshold for firing an action potential. Hyperpolarization, on the other hand, refers to an increase in the membrane potential, making it more difficult for the cell to generate an action potential.
Mechanism of Action
The mechanism of action of electrotonus involves changes in the flow of ions across the cell membrane in response to the applied electric current. These changes in ion flow alter the membrane potential of the cell, leading to changes in excitability. This process is crucial for the transmission of electrical signals in the nervous system and the contraction of muscle cells.
Overall, electrotonus plays a significant role in the functioning of the nervous system and muscle cells. Understanding the mechanisms and effects of electrotonus is essential for researchers and healthcare professionals in diagnosing and treating various neurological and muscular disorders.
