Question

Nerve impulse travel through synapse with the help of ____.

• A. Choline
• B. Choline and acetylcholine
• C. Adrenaline and noradrenaline
• D. Valine

Answer 1

The correct option is C Adrenaline and noradrenaline

Synapse is the place where the axon of one neuron meets the dendrite of another. Synapses are also found between neurons and other types of cells, such as muscle cells.

The following steps describe what happens when a nerve impulse reaches the end of an axon:

1. When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters.
2. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron.
3. Neurotransmitters bind to the membrane of the dendrite.
4. The binding allows the nerve impulse to travel through the receiving neuron.

Examples of neurotransmitters are adrenaline and noradrenaline

Thus, nerve impulse move across the synapse, using chemicals called neurotransmitters. Hence, answer is 'Adrenaline and noradrenaline'
