Questions and Answers

The autonomic nervous system is divided into two main branches, what are they?

  • Somatic Nervous System (SNS) and Autonomic Nervous System (ANS)
  • Sympathetic Nervous System (SNS) and Autonomic Nervous System (ANS)

    Study Notes

    Autonomic Nervous System Overview

    • The autonomic nervous system is divided into two main branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).
    • These systems work in opposition to maintain homeostasis and respond to physiological demands.

    Sympathetic Nervous System (SNS)

    • Often called the "fight-or-flight" system.
    • Prepares the body to respond to stress or emergencies.
    • Key functions related to respiratory therapy include:
      • Bronchodilation: Relaxes bronchiole smooth muscles, widening airways and increasing airflow. Important during exercise and stress.
      • Increased Respiratory Rate: Increases respiration rate to ensure adequate oxygen delivery to muscles and vital organs during high demand.
      • Reduced Mucus Production: Decreases mucus secretion, helping keep airways clear during high demand.

    Parasympathetic Nervous System (PNS)

    • Often called the "rest-and-digest" system.
    • Promotes relaxation and energy conservation.
    • Key functions related to respiratory therapy include:
      • Bronchoconstriction: Contracts bronchiole smooth muscles, narrowing airways. Typically occurs during rest and sleep.
      • Decreased Respiratory Rate: Slows respiratory rate, promoting relaxed breathing.
      • Increased Mucus Production: Increases mucus secretion to trap and remove particles from the airways.

    Clinical Implications for Respiratory Therapists

    • Respiratory therapists need to understand these mechanisms to effectively manage and treat patients.
    • This knowledge is crucial in various scenarios including asthma, COPD, acute respiratory distress, ventilator management, and weaning from mechanical ventilation.
