What is the relationship between a stimulus and a nerve impulse?

∙ 9y ago
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.

∙ 12y agoAfferent impulses travel from the receptor cells (which detect the stimulus) to the cells of the central nervous system.
Efferent cells travel from the CNS to the motor (effector) cells.
Afferent - sensory
Efferent - motor
Interneurons travel between them.

What picks up a stimulus from the environment and changes it into a nerve?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
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.
What neuron picks up a stimulus?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
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
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.
What picks up a stimulus from the environment and changes it into a nerve?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
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.
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.
What is a nerve message called?
Well they are sent through the nervous system.
What neuron picks up a stimulus?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
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
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 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.
What happens for the perception of sensation to take place?
stimulus present, receptor activated, nerve impulse conduction
What is the path a nerve impulse travels throughout your body from stimulus to response-?

Does brain have nerve?
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.
What is the difference between a stimulus impulse receptor and effector?
A Receptor is referring to a sense organ, like a nerve ending. An Effector is referring to a muscle capable of reflecting to a stimulus. By definition, receptor and effector are antonyms.
