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 a response.
Response. The stimulus is the light.
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).
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)
Physiological adaptions are short-term changes in response to a particular environmental stimulus.
A stimulus is an external event that triggers a response in an organism. A response is the reaction or behavior that an organism exhibits as a result of a stimulus. In short, a stimulus is the input, while a response is the output.
The time it takes from recognizing a stimulus to the initiation of a muscle response (the muscle response can be recorded using an EMG).
A response caused by a neutral stimulus is known as a conditioned response. This occurs when the neutral stimulus becomes associated with a unconditioned stimulus through conditioning, leading to a learned response.

A response.
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.
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.
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.
Classical conditioning involves the pairing of a neutral stimulus with an unconditioned stimulus to create a conditioned response. The key elements include an unconditioned stimulus that naturally triggers a response, a neutral stimulus that initially does not elicit a response, and the pairing of the two stimuli to produce a conditioned response. Over time, the neutral stimulus alone can evoke the conditioned response.

Tropism is the response plants have towards external stimulus.
