Is a rabbit runs away from a fox an example of an internal stimulus?
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".
What is hypobiosis?
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).
What is the first structure a fertilized egg makes?
Embryoembryo
Why do zombies want to eat people?
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.
How is the functioning of brain different in different human beings although everyone has a similar braini.e everyone has similar parts of brain?
All humans (aside from those with brain differences due to injury or disease) have the same brain structures of relatively the same size. What makes us different is the way our brains are "wired" which has to do with the stimulus we are exposed to, as well as genetic factors.
What makes a neuron receive a stimulus?
An interaction with the world.
Learning that makes a reflex response to a stimulus other than the original natural stimulus that naturally produces the reflex?
classical conditioning
Specialized cell that makes up the nervous system?
The cells that makes up the nervous system is the Inter-neuron (circuit neuron), sensory neuron and motor neuron.
When you touch something hot a neuron in your fingers senses the temperature which best decscribes the first reaction the neuron has?
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.
How does the nervous tissue cause action?
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 .
What is the reflex action when you jump in a scary movie?
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 !!!!
What happens after the spinal cord makes a decision in a reflex?
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.
If a signal from a sending neuron makes the receiving neuron more negative inside?
The receiving neuron is less likely to generate action potential.
What makes up the bulk of the brain?
The Neuron.
What is a stimulus that makes him start hunting?
Not sure
How is the brain involved in a reflex arc?
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)
What is the stimulus that makes cats start hunting?
Not sure
