No, that would be an example of external stimulus. The fox is external to the rabbit.Internal stimulus is stimuli that comes from inside our own bodies, for example:my stomach is empty and this stimulates my stomach to "growls" so I go and find something to eat.External stimulus is stimuli that comes from outside our own bodies, for example:I walk past a hamburger shop and the smells stimulates nose and makes my mouth water for a "Big Mac" or a "Whopper", so I go inside and order the "full meal deal".
Hypobiosis is an arrested state of development that is usually seen with larvae of nematodes. It is where the larvae are in an inactive state for a period of time, then a stimulus of some kind makes them active again (it is not always known what this stimulus is).
There isn't a specific term for a person who makes you yawn. Yawning is a natural physiological response that can be triggered by various factors, including fatigue, boredom, or seeing someone else yawn.

It is an instinctive response so the zombie virus will be able to be spread to new carriers. Zombies do not actually need to eat to survive, but the virus makes it an undeniable instinct to insure further infection.
An interaction with the world.
This type of learning is known as classical conditioning. In classical conditioning, a neutral stimulus is paired with an unconditioned stimulus, which elicits an unconditioned response. Over time, the neutral stimulus becomes a conditioned stimulus that elicits a conditioned response. Famous experiments carried out by Ivan Pavlov with dogs are a classic example of classical conditioning.
Ions flow into the neuron. An action potential forms moves along the neuron. A response occurs, here, an aversion response... your body pulls your hand and finger away.
The stimulus sends a signal to the sensory neurons, the sensory neuron brings it to the spinal cord or brain as the interneuron continues bringing the message. When it reaches the brain, the brain makes a decision, and sends it back down the spinal cord with the interneuron and passes the decision to a motor neuron. The motor neuron carries the decision to the designated muscle, and the muscle makes the move. Obviously all of this happens within a second. You wouldn't notice your reaction to the stimulus until it has happened since you react to stimulus very often. I'm sorry if this is a bit off topic, but I .
There are no "decisions" involved in a reflex. Generally the response is to trigger whatever motor nerves move the affected area away from the stimulus.
1. Stimulus; Horror Movies 2. Sound Receptor Stimulated; The Eyes/ Sight and the Ears/ Sound are the only senses that makes you jump when watching a scary movie, (Your taste or touch doesn't make you jump when watching a scary movie) 3. Signal sent along Sensory Neuron 4. Signal passed along Relay Neuron (message sent to Brain) 5. Signal sent along Motor Neuron 5. Effect or Muscle Contracts (Response) ________________________________________________ So the Reflex Action is your Muscles because they respond to the Receptor !!!!
The receiving neuron is less likely to generate action potential.
The Neuron.

yes brain i s involved in reflex actions as it makes a pathway for sensory neuron to connect with and brain then directs the motor neuron to take a particular action which is given by effector !(muscles)
