The nasal mucosa

Area of Science:

  • Physiology
  • Neuroscience
  • Vascular Biology

Context:

  • The nasal mucosa performs vital functions like filtering air and regulating its temperature and humidity.
  • Its microcirculation is crucial for these functions and for nasal cycle dynamics.
  • Understanding nasal mucosal physiology is key to managing respiratory conditions.

Purpose:

  • To review the unique vascular architecture and complex innervation of the nasal mucosa.
  • To examine the roles of chemical mediators in nasal pathophysiology.
  • To explore microcirculation changes in nasal allergy and cold exposure.

Summary:

  • This review details the nasal mucosa's vascular and neural systems, including sympathetic, parasympathetic, and sensory nerve involvement.
  • It discusses chemical mediators like norepinephrine, neuropeptide Y, ATP, acetylcholine, vasoactive intestinal polypeptide, and nitric oxide.

Related Experiment Videos

  • The review highlights the current understanding of microcirculation in nasal allergy and cold exposure, noting that the mechanism of nasal congestion requires further elucidation.

    • Impact:

    • Provides a comprehensive overview of nasal mucosal physiology and microcirculation.
    • Identifies gaps in knowledge regarding nasal congestion mechanisms.
    • Suggests that further research could lead to improved treatments for nasal symptoms.
