If you touch a hot stove, your spinal cord can prompt you to withdraw your hand without having to send the message all the way to the brain. This is due to what scientists call __________.

Answers

Answer 1

Answer:

The reflex arc

Explanation:

The reflex arc is a pathway in which sensory receptors sense the stimulus and the sensory neurons carry the sensory information to the spinal cord. Here, the spinal cord serves as the integrating center. It sends the motor information via motor neurons to the effector organs. This pathway followed by nerve impulses is called reflex arc in which the information is not sent to the brain for processing. This allows a quick generation of responses called reflexes. Touching a hot stove is sensed by the thermoreceptors of skin and the information follows the reflex arc to generate response.

Answer 2
Final answer:

The phenomenon described is a reflex arc, an automatic response to a specific stimulus that bypasses the brain to quickly prompt a reaction, like withdrawing a hand from a hot stove.

Explanation:

What you're referring to is what scientists call a reflex arc. A reflex arc is an automatic, involuntary response to a specific stimulus, such as pain from touching a hot surface. Unlike other types of nerve signals, the signals from a reflex arc don't need to go all the way to the brain to be processed. Instead, the signal goes to the spinal cord, which then sends a signal back to the muscles, prompting you to draw your hand away. This bypass of the brain helps speed up response time, which can be crucial in preventing injury.
