depolarisation

membrane depolarisation occurs when the membrane potential becomes less negative.

neuronal depolarisation is essential for signal transmission in the brain.

the depolarisation threshold must be reached for an action potential to fire.

sodium channels mediate the rapid depolarisation phase of the action potential.

synaptic depolarisation occurs when neurotransmitters bind to postsynaptic receptors.

the depolarisation wave propagates along the axon during nerve impulse transmission.

calcium entry follows depolarisation and triggers neurotransmitter release.

cardiac depolarisation coordinates the contraction of heart muscle cells.

depolarisation of the muscle fiber leads to mechanical contraction.

voltage-gated sodium channels open during depolarisation.

the depolarisation process can be modulated by various pharmacological agents.

abnormal depolarisation patterns are associated with several neurological disorders.
