Lecture 56-57: Cervical Fascia and Spaces - True False

Comments:
: True False Questions : 1. The superficial cervical fascia, but not the prevertebral or the pretracheal fascia, envelops the strap muscles. : 2. The axillary artery, but not the subclavian vein passes through the interscalene triangle. : 3. The posterior scalene muscle is the posterior boundary of the interscalene triangle. : 4. The superficial cervical fascia has a superior attachment at the superior nuchal line. : 5. Posterior to the buccopharyngeal fascia and anterior to the alar layer of prevertebral fascia is the "danger" space. : 6. Immediately anterior to the alar layer of prevertebral fascia is the retropharyngeal space. : 7. The carotid sheath receives contributes from each of the named deep cervical fasciae. : 8. The vagus nerve, within the carotid sheath, lies anterior to the common carotid artery. : 9. The internal jugular vein, within the carotid sheath, lies lateral to the common carotid artery. : 10. The prevertebral fascia splits in either side of the manubrium and forms the suprasternal space. : 11. The superficial cervical fascia is deep cervical fascia. : 12. The long thoracic nerve typically pierces the posterior scalene muscle inferior to the dorsal scapular nerve. : 13. The most inferior attachment of the superficial cervical fascia, at the vertebral spines, is the to spine of the second thoracic vertebra. : 14. The tracheoesphageal groove is within the pretracheal fascia. : 15. The spinal accessory nerve enters the posterior triangle superior to the supraclavicular nerves. : 16. The phrenic nerve crosses the anterior scalene deep to pretracheal fascia. : 17. The inferior thyroid artery passes the posterior aspect of the carotid sheath. : 18. The suprascapular and transverse cervical arteries cross the anterior scalene superficial to the prevertebral fascia. : 19. The axillary sheath is a diverticulum of the prevertebral fascia. : 20. The external jugular vein is formed by the confluence of the retromandibular vein and the facial vein. : 21. The maxillary vein, by way of the pterygoid venous plexus, communicates with the cavernous sinus. : 22. Veins of the orbit provide communication between the region of the face and the cavernous sinus. : 23. The facial vein and its tributaries are considered to be valveless. : 24. The interval between the heads of origin of the sternocleidomastoid muscle provides a surface landmark for accessing the subclavian artery. : 25. Infection within the pretracheal space may spread to the superior mediastinum. : 26. Infection within the retropharyngeal space may spread to the posterior mediastinum. : 27. Infection within the "danger" space may spread throughout the abdominopelvic cavity. : 28. An intraoral object (toothbrush or pencil) that penetrates the "throat" might sever the internal carotid artery, introduce infection into the retropharyngeal space, and introduce infection into the "danger" space.
