These statements and questions are provided as a study aid to help you gauge your level of understanding of the region. A link to the Forum is provided if you are unsure of specific statements and questions and wish to discuss them.
1. The right sternocleidomastoid turns the face to the right.
2. Trunks and cords of the brachial plexus are in the posterior triangle of the neck.
3. The cutaneous branches of the cervical plexus emerge at the anterior border of the sternocleidomastoid.
4. The cervical plexus gives off only cutaneous branches.
5. The cervical plexus is formed by the ventral rami of C1-C4.
6. The sternocleidomastoid has a dual nerve supply.
7. Which cervical fasciae did you remove during your dissection?
8. The phrenic nerve and the subclavian vein pass between the anterior and middle scaleni muscles.
9. What is contained within the carotid sheath?
10. The only cranial nerves seen during dissection of the neck are IX, X, and branches of V.
11. The infrahyoid muscles are supplied by a branch of the hypoglossal nerve (superior root of the ansa cervicalis).
12. Which muscles can elevate the hyoid bone?
13. The submanibular ganglion is attached to the lingual nerve.
14. The superior thyroid arteries are the only blood supply of the thyroid gland.
15. The parathyroid glands are usually located on the lateral margins of the lobes of the thyroid gland.
16. Extrinsic and intrinsic muscles of the tongue are supplied by C.N. XII.
17. Common sensation to the entire tongue is supplied by IX; taste fibers to the anterior two third are from VII, and to the posterior one third from IX.
18. Submandibular and sublingual glands open into the oral cavity at the sublingual papilla on either side of the frenulum.
19. The thoracic duct normally enters into the left junction of internal jugular and subclavian veins.
20. The enveloping (superficial) cervical fascia encloses the sternocleidonastoid and trapezius muscles.
21. The submandibular gland is closely related to the lingual artery.
22. The superior laryngeal nerve supplies all intrinsic muscles of the larynx.
23. The buccinator, being a muscle of mastication, is supplied by V3.
24. Terminal branches of the three divisions of the trigeminal nerve pass through forminae on the anterior aspect of the skull.
25. The parotid duct courses transversely across the face and enters the vestibule of the oral cavity opposite the second upper molar.
26. The buccal fat pad is not present in the infant.
27. All openings in the face are surrounded by circular muscles.
28. The muscles of the mastication are derived from the first branchial arch, and are supplied by the mandibular nerve.
29. The medial pterygoid is the only muscle that can assist in the opening of the jaw.
30. Which gland is traversed by a cranial nerve and its branches.
31. The chorda tympani carries taste and preganglionic sympathetic fibers.
