Which body system does trismus primarily affect?

Nervous system
Muscular system
Dental or oral system
Respiratory system

The correct answer is: Dental or oral system

Trismus primarily affects the muscular system, specifically the muscles controlling jaw movement. This condition is commonly referred to as "lockjaw" and is characterized by a significant reduction in the ability to open the mouth due to spasms or rigidity of the masticatory muscles. It's often associated with various conditions, including infections, trauma, or dental issues, affecting the oral and dental areas. While the dental or oral system is impacted by trismus due to its implications for functionality related to oral health, it is the underlying musculature that is primarily responsible for the symptoms experienced by the patient. Understanding this condition is vital for paramedics, as it can indicate underlying health issues that may require further evaluation or intervention.
