Question

One advantage of a reflex response in the survival of an organism is
A. that sensory neurons carry impulses to the spinal cord which then sends a response to the muscle via the motor neurons causing a reaction.
B. the signal has to travel all the way to the brain before an action is taken by the body.
C. that motor neurons carry impulses to the spinal cord which then sends a response to the muscle via the sensory neurons causing a reaction.
D. the signal does not have to travel all the way to the brain before an action is taken by the body.

Answer 1

D, a reflex response occurs when a sensory neuron sends an impulse to the spinal cord, the spinal cord recognizes that the impulse is extremely strong, instead of this impulse going to the brain to be interpreted the spinal cord recognizes the strength of the signal and responds to it by sending a neuromuscular contraction signal which causes an immediate reaction. This means that the response is much quicker to a dangerous or strong stimulus because the signal relays off the spinal cord instead of the brain.
