It is then possible for the brain to modify or 'condition' some reflexes
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.
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.
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.
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.
A reflex action or reflex arc bypasses the brain as to decrease transmission time from detection to response, i.e. the time it takes for the body to initiate a response in relation to the effecting stimulus. This decrease in time allows for minimal damage to tissue or surrounding cells which may be affected by a certain stimulus.

Protection(?)
Reflex actions are sudden responses, which do not involve any thinking.
i think its the brain...
brain and the spinal cord will reaction
because it is the cells
eating
No, it is by definition involuntary. The neural impulses which cause the action do not go through the brain at all.
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.
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)
