Question

structures that transmit messages from one area of the body to another are called:
○ muscles.
○ nerves.
○ tendons.
○ arteries.

Explanation:

• Muscles are for movement and force generation, not message transmission.
• Nerves are specialized structures that transmit electrical and chemical signals (messages) between different parts of the body, including from the brain to muscles or sensory inputs to the brain.
• Tendons connect muscles to bones, aiding in movement but not message transmission.
• Arteries carry blood, not messages.
