The speed of nerve impulse transmission changes as the body ages. In infants, the transmission speed is only about half that seen in adults. By age five, most people have attained the adult velocity. A gradual decline in conduction velocity begins as people reach their 20s, and continues for the remainder of life.
Another factor that influences conduction velocity is the length of the nerve itself. An impulse that has to travel a longer distance will take longer. Some nerves are naturally longer than others. Measurement of nerve conduction takes into account the length of the target nerve.
Some other factors are:
· Initiation of action potential in nerve fibers;
· Conduction of impulse;
· Release of acetylcholine from the nerve terminals;
· Binding of acetylcholine to receptors of the motor end plate;
· Depolarization of the end plate;
· Initiation of action potential in muscle fibers;
· Muscle contraction.

An organism reacts to a stimulus with an?
An organism reacts to a stimulus with a response.
Is a plant growing towards light a response or stimulus?
Response. The stimulus is the light.
What is a change in the environment that causes a. Response?
stimulus
How do organisms react to a stimulus?
Practically anything can be a stimulus, so organisms can respond to them in just about any way. The definition of 'stimulus' and 'response' are a little paradoxical in this context in that a stimulus is anything that provokes a response and a response is anything done to react to a stimulus. Perhaps some examples will make it clearer: if a predator grasps a lizard's tail (stimulus) it will detach the tail and escape (response). If the weather is excessively hot (stimulus), a plant will close the stomata in its leaves to conserve water (response). If a laboratory mouse notices a new object in its cage (stimulus), it will go investigate it (response).
How does a stimulus and a reaction work?
A reaction is any response to a stimulus. Example:There's a loud noise (Stimulus), the dog turns his head to look for the noise (Response)
How do organism respond to short term changes in the environment?
Physiological adaptions are short-term changes in response to a particular environmental stimulus.
What is the premotor phase of reaction time?
The time it takes from recognizing a stimulus to the initiation of a muscle response (the muscle response can be recorded using an EMG).
What is the difference stimulus and response?
Stimulus is a reason, and response is the respose to that
An organism reacts to a stimulus with an?
An organism reacts to a stimulus with a response.
Is sunlight a reaction to stimulus?
A response.
What is a naturally occurring reaction to a particular stimulus?
The reaction to a stimulus is called a response. An intensified stimulus usually evokes a more intense response. Of course the type of response to a stimulus depends on the nature of the stimulus. Scream at someone and they likely will feel verbally attacked. The screaming is the stimulus, feeling attacked is the response.
Are stimulus and response the same thing?
No, stimulus is the cause and response is the effect. In feeding an animal, giving it food is the stimulus and it eating the food is the response.
What is the conditioning stimulus?
We refer to a conditioning stimulus and conditioned response. The conditioning stimulus is feedback that creates, enhances or intensifies a reaction, which is the conditioned response. In a famous series of experiments by Dr. Ivan Pavlov in the late 19th Century, dogs drooled when he gave them food and rang a bell rung at the same time. After awhile the dogs drooled at just the sound of the bell. The sound of the bell was the conditioning stimulus, and the physiological reaction of salivation in the dogs was the conditioned response.
What is the plant's response to the stimulus?
Tropism is the response plants have towards external stimulus.
Is a plant growing towards light a response or stimulus?
Response. The stimulus is the light.
What response is caused by a neutral stimulus?
The neutral stimulus does not cause any response. It is paired with the Unconditioned Stimulus until it is turned into the Conditioned Stimulus.
What are the elements of classical conditioning of psychology?
1. Neutral Stimulus(NS)-A stimulus that does not evoke a response 2.Unconditioned Stimulus(US)-A stimulus innately capable of eliciting a response 3.Conditioned Stimulus(CS)-A stimulus that evokes a response b/c it has been paired with an unconditioned stimulus 4.Unconditioned Response(UR)-An innate reflex response elicited by a US 5.Conditioned Response(CR)-A learned response elicited by a CS
