Reflex actions are sudden responses, which do not involve any thinking. For example,
when we touch a hot object, we withdraw our hand immediately without thinking as
thinking may take time which would be enough to get us burnt.
The sensory nerves that detect the heat are connected to the nerves that move the
muscles of the hand. Such a connection of detecting the signal from the nerves (input)
and responding to it quickly (output) is called a reflex arc. The reflex arcs −connections
present between the input and output nerves − meet in a bundle in the spinal cord. Reflex arcs are formed in the spinal cord and the information (input) reaches the brain.
The brain is only aware of the signal and the response that has taken place. However,
the brain has no role to play in the creation of the response.

What are two somatic reflexes in which the higher brain centers participate?
The Human Reflex Physiology Review Sheet states that "Conversely, other reflexes require the involvement of the brain, since many different inputs must be evaluated before the appropriate reflex is determined. Superficial cord reflexes and pupillary responses to light are in this category" (p. 342).
The role of fallacious reasoning in irrational action?

What role does the brain play in a reflex response?
withdrawal reflex involves the processing of brain. it integrates with cerebellar activity
What is a automatic action that does not involve the brain?
Reflex actions are sudden responses, which do not involve any thinking.
In some reflex action skeletal muscles contract without the involvement of the?

Can part of the impulse in a reflex action reach the brain?
because it is the cells
Give an example a reflex action?
brain and the spinal cord will reaction
Why is it important for the brain to be kept informed of reflex action?
It is then possible for the brain to modify or 'condition' some reflexes

What is reflex and complex behavior in animal systems?
reflex action is that immediate response to the external stimuli which is provided for the spinal cord itself and not the brain and further the complex action is taken by brain by further thinking upon the matter
Is a reflex is a voluntary action?
No, it is by definition involuntary. The neural impulses which cause the action do not go through the brain at all.
How is a reflex action different from a normal response to a stimulus?
It doesn't need to involve the brain.
What is the path that nervous impulse takes through the nervous system?
sensory neurone --> enters spinal cord --> relay neurone --> brain(is not a reflex action) or motor neurone(if action is reflex)
