Why is it advantageous for a person that the impulse passes through the reflex arc first before it is relayed to the brain?

One example is touching something very hot that might burn you: the reflex can pull the hand away from the hot object much quicker than the brain could decide if it was dangerously hot and pull the hand away. This reduces exposure to the heat and possible severity of any burn that might happen.
Of course the brain could then decide to risk touching the hot object again to better determine if it is actually dangerously hot or if the reflex just overreacted.

What is the correct order that information passes through in a neuron?
The flow of information across nerve cells is called a nerve impulse in which the axons of the cell must depolarize, repolarize and go through a refractory period before reaching the resting potential. At this point, another impulse can occur.
What is a bedtime story?
A bedtime story is a story relayed to somebody, usually a child, before they go to sleep.
What is a sentence for impulse?
i act on impulse. hes an impulse buyer. i never think before i act, i just do what my impulse says. sorry i know theyer not the best...
The neurons that would pick up sound first before it is even relayed to the brain are called?
connecting neurons
Which part of the heart delays the electrical impulse to allow for atrial emptying of blood before ventricular contraction?
The AV node slows down the impulse giving the atria time to contract before the ventricles contract.
Would it be advantageous to group the data before constructing a frequency distribution?
The answer depends on the nature of the data and the domain. If the domain is continuous or very large relative to the number of observations, then it is very advantageous.
What is impulse momentum equation?
It is F*t = m*dV or F*t = m*v - m*uwhere:F is the force, acting for time t,m is the mass of the object, dV it the change in its velocityu and v are the velocities of the object before and after the impulse.
How many number of synapses that must be crossed before an afferent nerve impulse becomes a perception?
three
What sentence can go with the word impetuous?
It was an impetuous impulse, I bought the shoes before considering what it would do to my budget.
An important landmark when taking the apical pulse before administering cardiac drugs is the?
point of maximum impulse (PMI)
Where in the heart do electric impulses begin?
In a normal heart, the electrical impulse resulting in depolarization and contraction of the cardiac muscle originates in the sinoatrial (SA) node and propagates through the atria to the atrioventricular (AV) node before moving on to the ventricles. When the electrical impulse for muscle contraction is generated, it travels throughout the muscle of each atrium, causing atrial contraction. the impulse then travels to the atrioventricular (AV) node. according to Medical Assisting- administrative and clinical procedures with anatomy and physiology.
Why do nervous impulses gradually reduce while doing a set of pushups?
A nervous impulse is the relaying of a signal from one part of the body to another in response to stimulus and is only conducted when the neuron has recovered from conducting its last impulse. When the body is under continuous pressure affecting blood circulation and the delivery of oxygen and nutrients the processes are impaired and therefore their ability to conduct nervous impulses is reduced as it takes longer for the impulse to rest before the regeneration of a new nervous impulse
