What effect does electrical shock have on a person’s muscles?

• A. They become relaxed
• B. They contract involuntarily
• C. They become numb
• D. They freeze momentarily

Answer: (B)

Electrical shock causes a person's muscles to contract involuntarily due to the stimulation of the nervous system. When an electrical current passes through the body, it disrupts the normal electrical signals that control muscle movement, leading to spasms or contractions. This involuntary contraction can be intense, potentially resulting in situations where the person cannot let go of the source of the shock, exacerbating the danger they are in.

Understanding this phenomenon is crucial, especially in emergency situations where immediate response is needed to prevent further injury. The other options suggest different reactions that do not accurately describe the body’s immediate muscular response to electrical shock. The body does not relax, become numb, or freeze in a way that halts all muscle activity; rather, it experiences a sudden and often forceful contraction.
