QUESTION 3 DOK 3 10 points Rachel accidentally touches a hot stove and then immediately reacts by removing her hand. Explain what signals are sent both from her hand (when she touches the stove) and then back to her hand (when she removes her hand) and from where they are sent in order for her to reac quickly. Click to answer

## Step 1<br />When Rachel touches the hot stove, her sensory receptors in her skin are activated. These receptors are responsible for detecting temperature and sending signals to the brain. The signal sent from her hand to the brain is a sensory signal, which is a type of signal that carries information about the environment.<br /><br />## Step 2<br />The brain processes this sensory signal and recognizes it as a painful stimulus. This recognition is due to the brain's ability to interpret sensory signals and determine the appropriate response.<br /><br />## Step 3<br />The brain then sends a motor signal back to Rachel's hand. This motor signal is a type of signal that carries instructions for action. The motor signal instructs the muscles in Rachel's hand to contract and pull away from the stove.<br /><br />## Step 4<br />The muscles in Rachel's hand contract in response to the motor signal, causing her hand to pull away from the stove. This is a reflex action, which is an automatic response to a stimulus.<br /><br />## Step 5<br />The reflex action is a protective mechanism that helps to prevent further injury. By pulling her hand away from the stove, Rachel avoids further contact with the hot surface and potential burns.
