In adults, the subglottis is generally flat against the lower edge of the 6th cervical vertebra in the cervical spine. The lower border of the larynx is located at the lower edge of the cricoid cartilage, which is generally flat against the lower edge of the 6th cervical vertebra. The larynx is a conduit for the passage of air in and out of the neck, and is also an organ of articulation, and functionally serves as a partial sense of taste. The larynx is also the upper border of the epiglottis, the location of the lower edge of the 4th and 5th cervical vertebrae, the position of women is slightly higher, because the larynx and the hyoid bone and pharynx are closely linked, so when swallowing, the larynx can be moved up and down. In the structure of the human body, the lower and upper laryngeal boundaries are the location of the larynx. The larynx is a conical tubular organ composed of a group of cartilages, ligaments, laryngeal muscles and mucous membranes, and by determining the discomfort of these two locations, it can be an aid in determining whether or not the lesion is in the larynx. If there is any discomfort in the larynx, it is recommended to consult a doctor in a timely manner, under the guidance of a professional doctor to clarify the cause of the disease and carry out targeted treatment.
