Anatomy of the Thyroid

Anatomy of the Thyroid

  • Location:

    • The thyroid gland is located in the anteroinferior region of the neck.
    • It is positioned at the level of the thyroid cartilage.
  • Structure:

    • The thyroid has two main lobes:
    • Right lobe
    • Left lobe
    • These lobes are connected by a region known as the isthmus.
    • The isthmus straddles the trachea anteriorly.
    • Boundaries:
    • Posterior/laterally:
      • The thyroid gland is bounded by the common carotid arteries (CCA) and the internal jugular veins (IJV).
  • Relevant Anatomical Features:

    • The cricoid cartilage is mentioned, indicating its proximity to the thyroid, though further details may be necessary for full understanding.
    • The superior thyroid artery is noted, implicating blood supply information relevant to the thyroid gland's anatomy.
