Carotid Sheath (Page 6)A tube of deep fascia that surrounds big vessels and nerves in the neck.Attachments:Above: To tympanic plate and petrous bone.Below: To fibrous pericardium.Anterior: to pretracheal fascia. Posterior: Prevertebral fascia.Dr.Sherif Fahmy
Contents:•Common and internal carotid arteries.•Internal jugular vein.•Vagus nerve. In the upper part lower 4 cranial nerves are present in the upper part of sheath.Structures embeded:-Ansa cervicalis in anterior wall.-Sympathetic chain in posterior wall.
