Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of impulse does a neuron fire when it is stimulated?
A
Electrical
B
Chemical
C
Mechanical
D
Peripheral
Explanation: 

Detailed explanation-1: -Neurons conduct electrical impulses by using the Action Potential. This phenomenon is generated through the flow of positively charged ions across the neuronal membrane.

Detailed explanation-2: -The electrical signals are action potentials, which transmit the information from one of a neuron to the other; the chemical signals are neurotransmitters, which transmit the information from one neuron to the next.

Detailed explanation-3: -The nervous impulse is also called ‘action potential’. It refers to the electric signal produced by a neuron when stimulated. This signal is then transmitted by synapses, or connections between the cells.

Detailed explanation-4: -When a neuron is stimulated, an impulse in the form of an action potential is generated which travels down the length of the axon, and towards a connecting neuron.
