1. The superficial cervical fascia, but not the prevertebral or the pretracheal fascia, envelops the strap muscles.

false- the strap muscles are not "enveloped" by any fascia. they are deep to the superficial cervical fascia and superficial to the pretracheal fascia

2. The axillary artery, but not the subclavian vein passes through the interscalene triangle.

false- the subclavian artery passes deep to the anterior scalene muscle to then exit through the interscalene triangle, but the subclavian vein does not pass through the triangle

3. The posterior scalene muscle is the posterior boundary of the interscalene triangle.

false- the middle scalene is the posterior boundary od the interscalene triangle

4. The superficial cervical fascia has a superior attachment at the superior nuchal line.

true- its superficial borders are the scalp posterior (more specifically nucal line) and the mandible anteriorly.

5. Posterior to the buccopharyngeal fascia and anterior to the alar layer of prevertebral fascia is the "danger" space.

false- this space would be the retropharyngeal space

6. Immediately anterior to the alar layer of prevertebral fascia is the retropharyngeal space.

true

7. The carotid sheath receives contributes from each of the named deep cervical fasciae.

true

8. The vagus nerve, within the carotid sheath, lies anterior to the common carotid artery.

false- it lies posterior to the common carotid and the internal jugular vein

9. The internal jugular vein, within the carotid sheath, lies lateral to the common carotid artery.

true

10. The prevertebral fascia splits in either side of the manubrium and forms the suprasternal space.

false- this would be the superficial cervical fascia that splits and makes the suprasternal space

11. The superficial cervical fascia is deep cervical fascia.

true

12. The long thoracic nerve typically pierces the posterior scalene muscle inferior to the dorsal scapular nerve.

true-?

13. The most inferior attachment of the superficial cervical fascia at the vertebral spines is the to spine of the second thoracic vertebra.

false- it extends down to vertebrae prominens (c7)

14. The tracheoesphageal groove is within the pretracheal fascia.

true- ?

15. The spinal accessory nerve enters the posterior triangle superior to the supraclavicular nerves.

true

16. The phrenic nerve crosses the anterior scalene deep to pretracheal fascia.

true- danger in anesthesia

17. The inferior thyroid artery passes the posterior aspect of the carotid sheath.

true-?

18. The suprascapular and transverse cervical arteries cross the anterior scalene superficial to the prevertebral fascia.

true

19. The axillary sheath is a diverticulum of the prevertebral fascia.

true

20. The external jugular vein is formed by the confluence of the retromandibular vein and the facial vein.

false- the external jugular is formed by the retromandibular and the posterior auricle vein

21. The maxillary vein, by way of the pterygoid venous plexus, communicates with the cavernous sinus.

true

22. Veins of the orbit provide communication between the region of the face and the cavernous sinus.

true- can spread infection

23. The facial vein and its tributaries are considered to be valveless.

true- can spread infection

24. The interval between the heads of origin of the sternocleidomastoid muscle provides a surface landmark for accessing the subclavian artery.

false- for accessing the phrenic nerve

25. Infection within the pretracheal space may spread to the superior mediastinum.

true- the pretracheal spaces inferior border is the superior mediastinum

26. Infection within the retropharyngeal space may spread to the posterior mediastinum.

true- this is where the buccopharyngeal fascia and the alar layer meet

27. Infection within the "danger" space may spread throughout the abdominopelvic cavity.

true- the danger space runs all the way down the poterior thorax, abdomen and stops in the pelvic 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.

true- ouch!
