WitrynaUnderstanding: • Nerve impulses are action potentials propagated along the axons of neurons. Nerve impulses are action potentials that move along the length of an axon as a wave of depolarisation. Depolarisation occurs when ion channels open and cause a … http://www.ib.bioninja.com.au/standard-level/topic-6-human-physiology/65-neurons-and-synapses/nerve-impulses.html

Can a single neuron carry nerve impulses in both directions?

WitrynaThe nerve impulse travels to the central nervous system (CNS). This consists of the brain and the spinal chord. It travels by "jumping" from one neurone to the next: the stimulus that the first neurone receives is changed into an electrical charge (the nerve impulse) that travels through the axon.

Why does an impulse only travel in one direction? – Wise-Answer

WitrynaNerve Impulse is defined as a wave of electrical chemical changes across the neuron that helps in the generation of the action potential in response to the stimulus. This transmission of a nerve impulse across the neuron membrane as a result of a … Witryna14 lut 2024 · A synapse is a small gap between two neurons, where nerve impulses are relayed by a neurotransmitter from the axon of a presynaptic (sending) neuron to the dendrite of a postsynaptic (receiving) neuron. It is referred to as the synaptic cleft or synaptic gap. During synaptic transmission, the action potential (an electrical … Witryna14 cze 2024 · Definition. A sensory neuron (sometimes referred to as an afferent neuron) is a nerve cell that detects and responds to external signals.
