Curare reduces the response to nerve stimulation because it acts as a neuro-muscular blocking agent, or muscle relaxant. It is also known as tubocurarine.

Electrical nerve stimulation
Electrical stimulation is typically the most effective method for nerve stimulation as it can directly trigger action potentials in the nerve fibers. Light and chemical stimuli can also stimulate nerves but are generally not as precise or efficient as electrical stimulation.
Vagus nerve stimulation in vasovagal attack in the cause of sinus bradycardia. Vagus nerve stimulation may stop the heart.
Electrical nerve stimulation is also known as neuromodulation. It involves using electrical currents to stimulate nerves in order to treat various medical conditions, such as chronic pain or movement disorders.
Vagal nerve stimulation is a medical procedure that involves delivering electrical impulses to the vagus nerve, which is a cranial nerve that plays a role in regulating many bodily functions. It is commonly used to treat conditions such as epilepsy and depression that have not responded to other treatments.
To prevent accommodation in nerve stimulation, vary the frequency or amplitude of the stimulus over time. This can help to maintain the effectiveness of the stimulation and prevent the nerve from becoming desensitized. It's also important to have a proper rest period between stimulation sessions to allow the nerve to recover.

Yes, coronary vessels have both parasympathetic and sympathetic innervation. Parasympathetic input leads to vasodilation of coronary vessels, while sympathetic input can cause vasoconstriction in response to stress or exercise. The balance between these two systems helps regulate blood flow to the heart.
Curare is a toxic substance that acts as a neuromuscular blocker, primarily affecting the body's ability to transmit nerve impulses to muscles. If swallowed, it is unlikely to be lethal because it typically requires injection to have its toxic effects. However, ingesting curare can still be dangerous, as it may cause gastrointestinal distress or other health issues. Always seek immediate medical attention if curare is ingested.
The vagal nerve stimulator has two parts: an electrode that wraps around the left vagus nerve in the neck; and a pulse generator, which is implanted under the skin below the collarbone. The two parts are connected by a wire.
