These impulses interfere with communication between which two systems?

• A. The circulatory system and the lungs
• B. The endocrine system and the liver
• C. The nervous system and the skeletal muscles
• D. The digestive system and the kidneys

Answer: (C)

Electrical impulses are the language of the nervous system, delivering quick, direct instructions to body parts. Motor neurons carry these nerve impulses from the brain or spinal cord to skeletal muscles, triggering contraction and movement. When these neural signals can’t reach the muscles, communication breaks down and muscle control is impaired. Other pairings involve signals that aren’t primarily neural impulses—hormonal signals between the endocrine system and the liver, or processes that rely on blood flow, digestion, or filtration rather than fast electrical signaling. So the pair most directly tied together by impulses is the nervous system and the skeletal muscles.
