What carries nerve impulses across the gap between two nerve cells?

Answers

Answer:

The correct answer is: axons.

Explanation:

Nerve cells, also called neurons, are composed of a body that contains the genetic information of the cell, and a few prolongations called dendrites and axons. These prolongations, especially the axons (which can be up to 1 meter long), carry the nerve impulses from one neuron's body to the other.

The nerve impulse is information in the form of neurotransmitters that is transmitted through the synaptic gap from the pre-synaptic neuron to the post-synaptic neuron.

The communication between the two neurons is called synapsis.

Neurotransmitters are molecules that have the capacity to excite or inhibit a certain response of a cell. For example, acetylcholine is a neurotransmitter that excites the muscle cells, making contraction of the muscle possible.
Neurons carry messages from dendrite across the myelin sheath to synaptic/axon terminals.
