What is the anatomical order of the larynx from superior to inferior?

  1. Cricothyroid membrane, thyroid cartilage, cricoid cartilage

  2. Thyroid cartilage, cricoid cartilage, cricothyroid membrane

  3. Thyroid cartilage, cricothyroid membrane, cricoid cartilage

  4. Cricoid cartilage, thyroid cartilage, cricothyroid membrane

The correct answer is: Thyroid cartilage, cricothyroid membrane, cricoid cartilage

The anatomical order of the larynx from superior to inferior starts with the thyroid cartilage, which is the largest of the laryngeal cartilages and located at the top. Below the thyroid cartilage is the cricothyroid membrane, a flexible tissue that connects the thyroid and cricoid cartilages. Lastly, the cricoid cartilage sits underneath the cricothyroid membrane, forming a complete ring around the airway at the base of the larynx. This sequence is vital for understanding both anatomical relationships and clinical procedures involving the airway, such as intubation or cricothyrotomy. The proper order aids in accurate identification of structures during examination or procedures.
