Brain send the message via nerve impulses involving neurons which use the neuro-transmitter Acetylcholine
Acetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
The response of an effector is the action or change that it produces in response to a stimulus. Effectors are organs or structures in the body that carry out the response, such as muscles contracting in response to a nerve signal. This response helps to bring about homeostasis and maintain the body's internal balance.
The short pathway that carries the impulse for an automatic response is called a reflex arc. It involves sensory neurons, interneurons in the spinal cord, and motor neurons to quickly produce a reflex action in response to a stimulus, bypassing the brain.
The "all-or-none" principle of nerve fibers means that once a certain threshold of stimulus intensity is reached, the nerve will fire an action potential with a consistent magnitude, regardless of the strength of the stimulus beyond that threshold. This means that while a stronger stimulus can increase the frequency of action potentials (the rate of firing), it does not affect the strength of each individual impulse. Thus, the response remains uniform in size, ensuring that the information conveyed relates to the stimulus intensity via the frequency of impulses rather than the amplitude of each impulse.
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.
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 stimulus is any event that evokes a specific response in an organism, while an impulse is a message carried by neurons in response to a stimulus. When a stimulus is detected by sensory receptors, it triggers an impulse that is transmitted through the nervous system to elicit a reaction or behavior.
the impulse from the stimulus is processed in the spinal cord and gives the response immediately they protect you
our senses will detect stimulus and send impulse into the integrating centre(brain) to interpret. the brain will produce appropriate response toward the stimulus to the effector. e.g when Telephone ring, the ears will detect the stimulus(sound) and the brain will produce the response to pick up the phone (copy from Yahoo answers)
a stimulus may be continous, an impulse ha a defined timeline

This response helps to bring about homeostasis and maintain the body's internal balance.
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.....

receptor
When a stimulus is received by a sense organ, it gets converted into electrical signals that travel through neurons to the brain. The brain then processes and interprets this information to create a perception of the stimulus, which can then lead to a behavioral response or action.
