depolarization Sentence Examples
- Depolarization is a crucial step in the initiation of action potentials in neurons.
- During depolarization, voltage-gated sodium channels open, allowing sodium ions to rush into the cell.
- The influx of sodium ions causes the cell membrane to depolarize, shifting the membrane potential towards a positive value.
- Depolarization spreads along the length of the neuron as adjacent regions of the membrane reach their threshold potentials.
- In cardiac physiology, depolarization refers to the contraction phase of the cardiac muscle cells.
- An electrocardiogram (ECG) detects the depolarization and repolarization events of the heart.
- Certain drugs can alter the rate or magnitude of depolarization in cardiac cells, affecting heart function.
- In nerve cells, depolarization occurs when excitatory neurotransmitters bind to receptors, triggering the opening of ion channels.
- Depolarization of the presynaptic membrane leads to the release of neurotransmitters into the synaptic cleft.
- Understanding the mechanisms underlying depolarization is essential for elucidating how neurons communicate and how the heart functions.
