The prevertebral fascia extends medially behind the carotid vessels, where it assists in forming their sheath, and passes in front of the
prevertebral muscles. The prevertebral fascia is fixed above to the
base of the skull, and below it extends behind the esophagus into the
posterior mediastinal cavity of the
thorax. It descends in front of the
longus colli muscles. The prevertebral fascia is prolonged downward and laterally behind the carotid vessels and in front of the
scalene muscles. It forms a sheath for the
brachial nerves,
subclavian artery, and
subclavian vein in the posterior triangle of the neck; it is continued under the clavicle as the axillary sheath and is attached to the deep surface of the
coracoclavicular fascia.
Relations The prevertebral fascia represents the floor of the
posterior triangle of the neck. The prevertebral fascia borders the vertebral compartment of the neck. ==References==
