Stimulating nerves cause the muscles to?

Weaken and Deteriorate
Expand and Contract
Stiffen
Shrink

The correct answer is: Expand and Contract

Stimulating nerves cause the muscles to expand and contract. This is because muscles are controlled by nerves and when stimulated, nerves send electrical signals to the muscles which causes them to contract and relax. Option A is incorrect because stimulating nerves does not weaken or deteriorate the muscles, but rather strengthen them. Option C is incorrect because stimulation does not cause muscles to stiffen, but rather become more flexible and mobile. Option D is incorrect because stimulating nerves does not cause muscles to shrink, but rather grow and become stronger.
