In a neuron, conversion of electrical signal to a chemical signal occurs at/in-A cell body B axonal end C dendritic end D axon
Question
In a neuron, conversion of electrical signal to a chemical signal occurs at/in:
- A) cell body
- B) axonal end
- C) dendritic end
- D) axon
Solution
The conversion of an electrical signal to a chemical signal in a neuron occurs at the axonal end. So, the correct answer is B - Axonal end.
Here's a step-by-step explanation:
- The process begins with an electrical signal, or action potential, in the neuron's cell body.
- This action potential travels down the length of the neuron's axon.
- When the action potential reaches the axonal end, it triggers the release of neurotransmitters, which are chemical signals.
- These neurotransmitters cross the synapse, or gap, between the axon of one neuron and the dendrites of the next neuron.
- The dendrites receive these chemical signals and convert them back into electrical signals for the neuron to process.
So, the conversion of electrical signals to chemical signals occurs at the axonal end of the neuron.
