excitatorních

Excitatorní refers to a process or substance that increases the activity or responsiveness of a cell, tissue, or organ. In a biological context, it most commonly relates to the nervous system and the transmission of nerve impulses. Excitatory neurotransmitters, for example, bind to receptors on a neuron and cause a depolarization of its membrane, making it more likely to fire an action potential. This excitation is a fundamental mechanism for communication within the nervous system, allowing for the rapid relay of information.

The term can also be applied more broadly to other physiological systems. For instance, certain hormones or drugs can have an excitatorní effect by stimulating increased metabolic rate, muscle contraction, or glandular secretion. The opposite of excitatorní is inhibitory, which refers to processes that decrease activity or responsiveness. Maintaining a balance between excitatorní and inhibitory influences is crucial for proper physiological function and overall homeostasis. Dysregulation of excitatorní processes can contribute to various neurological and physiological disorders.
