During the absolute refractory period along an axon membrane of a neuron?
the neuron is unable to respond to a stimulus of any intensity
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 does Weber's law refers to?
weber-fechner law (effect of intensity of stimulus on receptors) :- the frequency of the action potentials conducted along the afferent nerve fiber is directly proportional to logarithm of the intensity of the stimulus applied to the receptor. This means that an increase in the intensity of the stimulus leads to an increase in the amplitude of generator or receptor potential, that increase the frequency of the action potential conducted along the afferent fibers connected to the receptor.
A reflex arc begins with the stimulation of a what?
A reflex arc begins with the stimulation of a sensory receptor such as those on the skin. The stimulus is then passed as an electrical impulse along sensory, relay and motor neurones (by-passing the brain) before reaching an effector orgen, like a muscle, which then responds to the stimulus.
How does the rate of photosynthesis respond to changes in light intensity?
It directly increases along with the growth in intensity of the light

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 does your body do reaction to a 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.
What did Ivan Pavlov discover with regard to the digestive process of dogs?
When paired with an unconditional stimulus, a neutral stimulus can become a conditioned stimulus and produce the same response as the unconditioned stimulus.
