Which of the following is NOT a reason why a reflex arc is faster than a normal nerve transmission
select one:
a.) a reflex arc does not send information to the brain to be processed
b.) A reflex arc does not involve neurotransmitters
c.) A reflex arc stimulates the motor neurons for an immediate reaction
d.) A reflex arc involves fewer neurons

Hi Mekayle2,
A reflex arc does not send information to the brain to be proccessed, but instead uses the synapses in the spinal cord to stimulate motor neaurons. This allows for a faster reflex so that your hand is jerked off the hot stove instead of having your brain process the pain occuring, and then react. This means the reflex arc invloves fewer neurons to stimulate a faster response. The answer here will be B. The neurotransmitters from the interneuron axon in the spinal cord chemically reacts. This is what stimulates the motor neuron, trigguring the effector (muscle).
Hopefully this helps with your understanding. Have a great night! :)
