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.

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?

Yes, a stimulus needs to reach a certain threshold level of strength in order to generate a nerve impulse. This threshold is required to depolarize the cell membrane and initiate the action potential. If the stimulus is not strong enough to reach this threshold, no nerve impulse will be generated.


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.


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

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.


What at is a nerve stimulus?

A nerve stimulus is a signal or impulse that is transmitted along a nerve fiber, triggering a response in the body. This stimulus can be initiated by various factors such as touch, temperature, or pressure, and is essential for the communication between different parts of the nervous system.


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 happens for the perception of sensation to take place?

stimulus present, receptor activated, nerve impulse conduction

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 synaptic and nerve impulse transmission?

Synaptic transmission is chemical, while nerve impulse or axonal transmission is electrical.


What affects nerve impulse speed?

Nerve impulse speed is affected by the diameter of the nerve fiber (larger fibers conduct faster), the presence of myelin sheath (myelinated fibers conduct faster), and temperature (warmer temperatures enhance conduction speed). Additionally, the refractory period of the neuron and the strength of the stimulus can also influence nerve impulse speed.
