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).
What is another name for Hering Breuer reflexes?
The Hering-Breuer reflexes are also known as the "inflation reflex" and "deflation reflex." These reflexes help regulate breathing by preventing over-inflation of the lungs during inhalation and promoting exhalation when the lungs are deflated. They play a crucial role in maintaining respiratory rhythm and ensuring efficient gas exchange.
The role of fallacious reasoning in irrational action?
it is a reasoning that doesn"t make sense , false reasoning.
Who is Van Diesel?
His name is actually Vin Diesel and he is an American action movie star. He is famous for his role as Riddick in the Chronicles of Riddick series of movies and his role in The Fast and the Furious.
Who is going to play as Gandalf in The Hobbit?
Sir Ian McKellen will reprise his role as Gandalf in the live action adaptation of the Hobbit.
What does the reflex action involve?
Protection(?)
What is a automatic action that does not involve the brain?
Reflex actions are sudden responses, which do not involve any thinking.
What role does the brain play in a reflex response?
The brain initiates a reflex response by sending signals down the spinal cord to the specific muscle or organ involved. However, the actual reflex action occurs at the level of the spinal cord, without the need for input from the brain. This allows for a quicker and more automatic response to potentially harmful stimuli.
In some reflex action skeletal muscles contract without the involvement of the?
i think its the brain...
Give an example a reflex action?
brain and the spinal cord will reaction
Can part of the impulse in a reflex action reach the brain?
because it is the cells
Why is it important for the brain to be kept informed of a reflex action?
The brain needs to be informed of a reflex action to coordinate and modulate the response accordingly. This information allows the brain to adjust the reflex response based on the circumstances, ensuring appropriate reactions to stimuli and maintaining overall control of motor functions.
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
Automatic action that does not involve the brain?
eating
Does the nerve impulse reaches the brain during reflex arc?
No, during a reflex arc, the nerve impulse does not reach the brain before the reflex action occurs. Instead, the impulse travels from the sensory receptor through the spinal cord to the motor neurons, which directly trigger a response. This allows for a quick reaction to stimuli, bypassing the brain for immediate response. The brain may become aware of the stimulus and the reflex action afterward.
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.
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)
