The path a nerve impulse travels
Did you know?
WebbNerve impulses start in a dendrite, then move toward the cell body and down the axon. In the form of electrical and chemical signals, a nerve impulse travels along the neuron. A … Webb30 mars 2016 · Explanation: When the impulse (or 'action potential') reaches the presynaptic terminal (the end of the neuron), it causes a number of vesicles containing neurotransmitters to be released into the synaptic cleft (the bit between the two neurons).
Webb1. The resting neuron is inactive and polarized— the outside of the cell is positive from excess sodium and the inside is negative from excess chloride ions. 2. Stimulus reaches … Webb15 apr. 2024 · The neurotransmitters transmit the nerve impulse to the post synaptic fibre, by diffusing across the synaptic cleft and binding to receptor molecules on the post synaptic membrane. This results in a series of reactions that open "channel shaped" protein molecules. Electrically charged ions then flow through the channels in or out of the …
WebbA nerve impulse is an all-or-nothing response depending on if the stimulus input was strong enough to reach threshold. If a neuron responds at all, it responds completely. A greater stimulation does not produce a stronger impulse. Figure 8.4.2 An action potential speeds along an axon in milliseconds. Webb7 maj 2024 · Nerve impulses travel in one direction from the pre-synaptic to the post-synaptic neuron across a gap called a synapse. This is done to continue a nerve impulse …
