The stimulus is your bodies reaction to something, say you burnt your hand, this is the stimulus. The reaction is your bodies response to it. In this sense the stimulus will be sensed by sensory neurones which pass an electrical impulse through relay neurons until the impulse gets to the Central Nervous System. This then, gives out another impulse which travels down a Motor Neuron to the muscle telling your hand to be removed from the surface.....

Yes, when a receptor detects a stimulus, it triggers an electrochemical impulse to be sent along a nerve cell. This impulse travels to the brain where it is interpreted as a specific sensation or perception.
A nerve impulse travels from your leg to your brain through sensory neurons. Once in the brain, the impulse is processed, and a response is generated. The response travels back to your leg through motor neurons to initiate movement or action.
The neuron is the functional portion of the central nervous system, carrying impulses to the designated location. Neurons also have the role of interpreting an impulse, and waiting for a response. Neurons fall under the category of sensory neurons, interneurons and motor neurons.
A reflex is an automatic response, that protects the organism from a harmful stimulus. The receptors detect a stimulus which generates a nerve impulse along the sensory neurone to the Central Nervous System (CNS). The CNS decides the appropiate response to the stimulus. The nerve impulse then travels across a synapse to the relay neurone, across another synapse to the motor neurone to the effector. This is normally a muscle or an organ which moves or responds to bring about a response appropiate to the stimulus.
A Stimulus is picked up by a receptor, travels along a sensory neurone to either the spinal cord or brain, then it is processed to produce some response.
The nerve impulse typically travels from the sensory neuron to the spinal cord, where it is processed by interneurons, and then to the motor neuron to elicit a response from the effector organ or muscle.
An Impulse
a nerve impulse
The movement of positively charged atoms, such as sodium and potassium ions, in and out of channels in the axon's membrane generates an electrical signal called an action potential. This action potential serves as the neural impulse that travels along the axon to transmit information within the nervous system.
