Question

human reproductive system test unit test
what does your body send to the brain to make you move your hand when you touch a hot pot?
(1 point)
○ neurons
○ impulses
○ dendrites
○ synapse

Explanation:

To solve this, we analyze each option:

• Neurons are the cells that transmit signals, not what's sent.
• Impulses (action potentials) are electrical signals sent by neurons to communicate, like when touching a hot pot, the sensory neurons send impulses to the brain, and motor neurons send impulses to move the hand.
• Dendrites are parts of neurons that receive signals, not what's sent.
• Synapse is the junction between neurons, not the signal sent.

Answer:

B. impulses
