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.
Why does reflex reinforcement work?
Instead of being processed in the brain, a reflex arc is processed in the vertebra, this allows for faster reflexes. Example of when the reflex arc is used is when a person touches a hot stove. The immediate response (which the reflex arc causes) is to pull away, but it doesn't really hurt till a few seconds after. This is because the brain was first bypassed, but has now had time to process what happened.
What part of the body is not a reflex action in humans?
Conscious actions, such as voluntary movements controlled by the brain, are not reflex actions in humans. These actions involve decision-making and higher brain functions, unlike reflex actions which are automatic responses to stimuli.
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.
How do you know consciously what has happened in a reflex action?
In a reflex action, the body reacts automatically to a stimulus without involving conscious thought, as this process occurs in the spinal cord. However, the brain is still aware of the event once the reflex has taken place. This awareness typically comes after the action has occurred, allowing us to recognize and understand what happened. Essentially, while the reflex bypasses conscious control, the brain processes the experience afterward, enabling us to recall it.
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 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.
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
Automatic action that does not involve the brain?
eating

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.
What will happen if the reflex action do not work?
If the reflex action does not work, it could indicate a problem in the nervous system. This could result in difficulties with motor control and coordination, as well as a decreased ability to respond quickly to potentially dangerous stimuli. It is important to consult with a healthcare professional in order to determine the cause and appropriate treatment for the lack of reflex action.
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)
