WitrynaA 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. Witryna27 mar 2016 · There are several reasons nerve impulses only travel in one direction. The most important is synaptic transport. In order for a "nerve impulse" to pass from cell to cell, it must cross synaptic junctions. The nerve cells are lined up head to tail all the …

Witryna13 cze 2024 · All nerve cells (neurons) generally consist of 4 parts: the cell body, dendrites, an axon, and synaptic end bulbs. The nerve impulse flows in one direction. The dendrites receive incoming nerve impulses from other neurons, and the axon transmits the impulse to another neuron or receptor. The axon varies in length. WitrynaState the direction followed by a nerve impulse while travelling in the body of an organism. Answers (1) Nerve Impulse - A nerve impulse can be described as the electrical signal that transmitted along with a nerve fibre. The electrical impulse travels from dendrite to the cell body and then along the axon. can smells make you nauseous
