Anatomical terminology |
The pretracheal fascia is a portion of the structure of the human neck. It extends medially in front of the carotid vessels and assists in forming the carotid sheath.
Structure[]
The pretracheal fascia is continued behind the depressor muscles of the hyoid bone. After enveloping the thyroid gland, it is prolonged in front of the trachea to meet the corresponding layer of the opposite side. The pretracheal layer of the deep cervical fascia passes in front of the carotid sheath (i.e., common carotid artery, internal jugular vein, and vagus nerve) and in front of the cervical viscera (larynx, oesophagus, and pharynx). The muscular layer ensheathes the infrahyoid muscles.
Above, the pretracheal fascia is fixed to the hyoid bone. Below, it is carried downward in front of the trachea and large vessels at the root of the neck, and ultimately blends with the fibrous pericardium.[1]
The pretracheal fascia is fused on either side with the prevertebral fascia, and with it completes the compartment containing the larynx and trachea, the thyroid gland, and the pharynx and esophagus.[1]
Function[]
The pretracheal fascia encloses the thyroid gland, and is responsible for its movement during deglutition.
