What are the advantages of the fact that most reflex actions are governed by spinal cord?
Reflex actions are governed by three neurons only. If some body tries to hit on your eye, you blink by reflex action. Here again only three neurons are involved, although the middle neuron passes through your brain. Reflex action means only three neurons are involved and that saves lot of time required to think over the serious matter. So in reflex action you respond first and then brain notice the problem.The spinal reflex is fast. The reason it is fast is because the decisions are made at spinal cord level, rather than the nerves having to travel up to the brain and back down to the source.Because you are able to react quicker without having to think about it.1 It reduces the work load of brain. 2 The reflex action is under control of spinal cord, the message is sent to the brain later on.If it would have been under control of brain, it would have reqired longer duration for us to react, which has potential to cause damage to body tissue. Hence presence of spinal cord increases efficiency of reflex action.
What part of in pupil reflex for stimulus?
The stimulus in the pupil reflex would be light
What are the properties of reflex action?
The value of a reflex action is to survive. For example, if we place our hands on a hot oven. Our reflex would be to take our hand off and register the pain. OR A perfect example would be the rooting reflex. Which helps a breastfed infant find the mother's nipple. Babies display it only when hungry and touched by another person, not when they touch themselves.
When you learn something new you grow new neurons. What would you say to disprove this statement?
No. You don't grow new neurons, you grow more connections.
How many neurons does the human brain have per square inch?
"100 billion", that's how many neurons there are totally in the human brain, I am interested if I "cut" a part of the human brain that was a cubic inch how many neurons would be in there?
What Three kinds of neutrons that would be involved in a reflex impulse?
They are neurons and not neutrons. You have afferent neuron. Then you have intermediate neuron and then you have the efferent neuron in the reflex arc.

Describe the path an impulse would take for a reflex reaction?
Sensory neurons are responsible for sending the initial message. First to a local neuron, which in turn communicates with a motor neuron. Therefore it is causing a reflex.

You pull your hand away after touching a hot pan is this a somatic or automatic reflex?
This is an automatic reflex that occurs at the spinal cord level. It involves two neurons: one that brings "pain" information into the cord and one that carries the motor reflex out to the muscle. This is a very fast response. It would take longer to go the the brain and back. A third neuron often sends a "report" to the brain.
Is pupillary light reflex a monosynaptic or polysynaptic reflex?
It is Polysynaptic
What happens when your sensory neurons stop working?
You would not be able to feel anything so if you put your hand on a hot stove you wouldn't feel it but you would burn yourself badly, and you wouldn't have the reflex that the sensory neurons give you to pull your hand away quickly once you come in contact with heat.Elena
How do sensory neurons motor neurons and interneurons work together to produce a response to an environmental stimulus?
This forms what is called a reflex arc. If you would touch a very hot pan, your body will respond very fast to remove your hand before it burns badly. If you had to think about it, the burn would be more severe. So this bypassed the brain and is called a reflex arc. Sensory neurons sends info into the central nervous system (CNS), passes the info to the interneuron and it passes that to the motor neuron. The interneuron also send info to the brain and you note that "that is hot!". If you pay attention to this, you will see that you will remove your hand before you feel the burn.
What is the function of reflex arc?
The reflex arc allows sensory neurons to synapse in the spinal cord instead of the brain, allowing actions to occur relatively quickly by activating spinal motor neurons without needing to send signals through the brain. For example, a person touching a hot stove would flinch before thinking about it, and protect tissues from further damage.
What would life be like without neurons?
Neurons are the basic constituent of brain tissues. Without neurons person will be unable to do anything, to sense anything or to thing anything. Life would be extremely hard to imagine without the neurons. Neurons are part of nervous system.
Would salivary reflex be a somatic reflex?
In some circumstances I guess so.
What part of in pupil reflex for stimulus?
The stimulus in the pupil reflex would be light
