When considering pharmacological agents, it is essential to understand which branch they influence, as is the case when asking, **are muscarinic antagonists sympathetic or parasympathetic**? This article clarifies their specific mechanism of action and effects.

The hypothalamus, the body's internal thermostat, maintains a core temperature of around 98.6°F (37°C), but damage or dysfunction can lead to temperature dysregulation. Learning what are the symptoms of temperature dysregulation is the first step toward understanding and managing this complex issue.
