The venom of a black widow spider is toxic to the:

• A. A. Renal system.
• B. B. Respiratory system.
• C. C. Cardiovascular system.
• D. D. Nervous system.

Answer: (D)

The venom of a black widow spider primarily contains a neurotoxin called latrotoxin, which targets components of the nervous system. When injected, this toxin binds to nerve terminals, leading to the release of neurotransmitters, which can cause overstimulation of the nerves. This can result in a range of symptoms, including muscle spasms, severe pain, and neurological disturbances. The distinctive symptoms associated with black widow envenomation highlight its impact on the nervous system, such as tremors and severe abdominal cramping. These effects are a direct consequence of the neurotoxic properties of the venom. Understanding the mechanism of action of black widow venom emphasizes its specific threat to the nervous system and clarifies why this choice is identified as correct.
