It is limited to the front part of the neck, but more extensive than the name suggests


  • From hyoid bone to the superior mediastium.

  • Oblique lines of thyroid cartilage

  • Cricoid cartlage

  • The pericardium, and T. adventitia of the bases of great vessels.

  • Becomes continous with bucopharyngeal fascia covering constrictor muscles behind.


Structures sorrounded/ enclosed


  • Thyroid gland (1)
  • Infrahyoid muscles
  • Air and food passages

  • At the level of the thyroid isthmus a looser attachment of the pretracheal fascia occurs infront of trachea.
