What does the chemical reaction at the dendritic tip of a nerve cell in animals create?
Show answer & explanation
Correct answer: D
Explanation
Correct Answer:
Option 4 (An electrical impulse)
Explanation:
When information reaches the dendritic tip of a neuron in animals, a chemical reaction occurs. This reaction generates an electrical impulse. This impulse travels from the dendrite to the cell body and then through the axon to the end of the nerve.
Additional Facts:
Synapse: The space between two nerve cells is called a synapse, where the electrical impulse is transmitted to the next neuron via chemicals (neurotransmitters).
Parts of a Neuron: There are three main parts – dendrites, cell body, and axon.
Function: Nerve cells transmit information from one place to another in the body at the speed of electricity.
