What are the steps a nerve impulse travels throughout your body?

First stimulus received through the senses, Sense changed stimulus to an impulse than a sensory nerve capture the impulse, conducts the impulse to the spinal cord than the brain stem to the brain, then from the brain to the brain stem through the spinal cord to a motor nerve to a muscle or gland


What is the path a nerve impulse travels throughout your body from stimulus to response-?

The path a nerve impulse takes throughout the body depends on what the stimulus is. If it was a reflexive (motor) stimulus, the impulse would take the reflexive (motor) path. If the stimulus was just a discomfort, the path would be through the sensory nerves.


Which part of the neuron receives a stimulus and conducts the nerve impulse toward the cell body?

The dendrite receives a stimulus and conducts the nerve impulse toward the cell body.


How does a stimulus trigger a sensory response?

like electrical impulse


When the receptor have registered a the energy is converted to a electrochemical impulse?

stimulus


What is the relationship between a stimulus and a reponse?

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.....


What does your brains has to do with your nerves?

The nervous system is made up of three parts: the receptor, the decider, and the effector. The receptor receives an stimulus and creates an electric impulse to be sent to the brain. The brain receives this impulse and decides what to do in order to react to the stimulus. Your brain then makes a decision and sends out an electric impulse to the effector which moves the muscle or activates a gland in your body which is a reaction to the stimulus.


How do stimulus respond to human body?

a stimulus is an external factor that causes the nerve endings in your sesnse organ to send an electric impulse


The response of an effector is?

to provide a counter stimulus to neurons to transmit a negative feedback impulse to maintain homeostasis to decrease the external stimulus


Is conducting stimulus strong enough to generate a nerve impulse?

It depends on the strength of the stimulus. A threshold voltage has to be reached before the nerve can be stimulated.


When is an impulse an electrical signal?

When a stimulus causes positively charged ions to diffuse into the neuron.


What is the definition of weber's law?

The principle that for any change in a stimulus to be detected, a constant proportion of that stimulus (s) must be added or subtracted.


What is an effector organ in human biology?

Effector organ is a part of the body that responds to a stimulus and a stimulus is a change in the environment that is detected by a receptor. And is a receptor is a nerve cell that detects a stimulus.


What is a change that initiates an electrochemical message along a neuron?

A stimulus A stimulus is a change that starts an electrochemical charge, an impulse, moving along a nerve cell.


Describe the events that lead to the generation of a nerve impulse and its conduction from one neuron to another?

In order a nerve impulse to be generated there needs to be a stimulus. A stimulus would be you burning your finger or bumping your arm. Once the nerve impulse has been generated it sends off to the neurons in your brain so that your brain can tell you to move your hand.


What is the difference between membrane irritability and membrane conductivity?

Irritability is the ability to respond to a stimulus and convert it into a nerve impulse while conductivity is the ability to transport the impulse.


How do your reflexes help you?

the impulse from the stimulus is processed in the spinal cord and gives the response immediately they protect you


What do neurons pass impulses from?

I'm not really sure what your asking...but a neuron sends an impulse because of a stimulus from the enviroment. The sensory neurons then pick up that stimulus and send the impulse down and it leaves through the axon where it is then pick up by another neurons dendrites.


What are the two important principles related to nerve impulses?

1. The All-or-None Law states that the impulse is independent of the properties of the stimulus which started it. As long as the nerve cell is stimulated by an impulse of a certain minimal strength, it makes no difference how strong the exciting impulse is - just as a match or a blowtorch produces the same reaction in a fuse. It either fires or does not and there are no shades in between. The nerve impulse remains at the same strength as it travels along the nerve fiber, just as the spark remains at the same intensity as it moves along the fuse. The reason for this is evident in what has been said about a stimulus releasing energy in the fiber. It does not contribute energy.Impulse size and speed: The nerve impulse varies with the size of the fiber. (It is proportional to the square of the fiber's diameter.The size of the nerve impulse also depends on the condition of the fiber - being altered if drugged, deprived of oxygen, fatigued or in an abnormal state.2. The Frequency Principle states that there are more impulses per second with the stronger stimulus than with the weaker stimulus. A stronger stimulus produces impulses more frequently than the weaker stimulus. The frequency of nerve impulses is thus a function of the intensity of the stimulus.


What is the system's reaction to the stimulus?

Stimulus detected by receptors, transmitted to brain via afferent neurones, info processed at brain, efferent neurones, then to affector such as muscles.


What are two major functional properties of neurons?

the two major functional properties of neurons are: irritability (the ability to respond to a stimulus and convert it into a nerve impulse) and conductivity (the ability to transmit that impulse)


What is the correct order that the reflex arc travels in?

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.


How are stimulus and response related?

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)


Difference between sensory motor and interneurons?

Sensory neurons carry the impulse generated by the stimulus to the central nervous system, interneurons then carry the impulse through the central nervous system and the motor neurons then take the impulse from the central nervous system to effectors such as muscles and glands.


For a constant force suppose the duration of impact on an object is quintupled How much has the impulse changed?

The impulse is equal to the constant force so the impulse is also quintupled. The resting change in momentum has increased the exact same as well.
