Pretracheal fascia
Section of the neck at about the level of the sixth cervical vertebra. Showing the arrangement of the fascia coli.
Latin	lamina pretrachealis fasciae cervicalis
Gray's	subject #111 390

The pretrachial fascia extends medially in front of the carotid vessels, and assists in forming the carotid sheath.

It is continued behind the depressor muscles of the hyoid bone, and, after enveloping the thyroid gland, is prolonged in front of the trachea to meet the corresponding layer of the opposite side.

Above, it is fixed to the hyoid bone, while 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.

This layer 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.
