pobudliwoci
Pobudliwość, often translated as excitability, is a fundamental property of living cells, particularly nerve and muscle cells, that allows them to respond to stimuli. This response is typically in the form of an electrical signal. When a stimulus, such as a chemical neurotransmitter or mechanical force, reaches a certain threshold, it triggers a rapid change in the electrical potential across the cell membrane. This change, known as an action potential, propagates along the cell and initiates a specific cellular function, like muscle contraction or nerve impulse transmission.
The ability of a cell to exhibit pobudliwość is due to the presence of voltage-gated ion channels
Factors influencing pobudliwość include the concentration of ions inside and outside the cell, the number and
