This document discusses the anatomy of the jugular veins and related structures in the neck. It provides detailed diagrams and descriptions of the external jugular vein, internal jugular vein, and their tributaries. It also summarizes the carotid sheath that surrounds the common carotid artery and internal jugular vein, as well as surrounding muscles, nerves, and the cervical plexus. Finally, it briefly outlines the cervical part of the sympathetic trunk and its ganglia.

15. 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

16. 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.
