1.     I. The mastoid process, which is part of the occipital bone, serves as an
            attachment site for the sternocleidomastoid muscle.

         II. The clavicle bone serves as the inferior border of the occipital triangle.
 

2.     I. The clavicle is an attachment point for the omohyoid muscle.

         II. The splenius capitis muscle can be found superficial to the semispinalis
            capitis muscle.
 

3.     I. The levator scapulae is one of the muscles found in the floor of the
            posterior triangle behind the prevertebral fascia.

         II. The inferior oblique muscle attaches to the transverse process of C2.
 

4.     I. The prevertebral muscles, longus capitis and longus colli, are innervated
            by the dorsal primary rami.

         II. The cervical plexus is derived from the ventral rami of C1-C4.
 

5.     I. The levator scapulae receives innervation from both the cervical plexus
            and the dorsal scapular nerve.

         II. The transverse cutaneous nerve of the neck and the greater occipital nerve
            are cutaneous branches of the cervical plexus.
 

6.     I. Cutaneous nerves are typically deep to the deep fascia

         II. Fibers from the anterior loop of the ansa cervicalis innervates the
            geniohyoid muscle.
 

7.     I. The superior of the ansa cervicalis can be found medial to the common
            carotid artery.

         II. The stellate ganglion can be found at the level of the first rib, lying on the
            surface of the anterior scalene muscle and posterior to the common carotid artery.
 

8.     I. Both the middle cervical ganglion and stellate ganglion contribute fibers to
            the brachial plexus.

         II. The phrenic nerve lies posterior to the internal jugular vein.
 

9.     I. At C7 level, the common carotid artery is medial to the internal jugular vein.

         II. Pretracheal fascia can be found posterior to the esophagus.
 

10.     I. The laryngopharynx extends from the lower border of the cricoid cartilage to
            the upper border of the epiglottis.

         II. The stylopharyngeus muscle can be found posterior to the superior
            constrictor muscle.
 

11.     I.  All three constrictor muscles of the pharynx attach posteriorly to the
            pharyngeal raphe.

         II. The lateral pterygoid plate of the sphenoid bone serves as attachment site for
            the superior constrictor muscle.
 

12.     I. The torus tubarius is the prominent ridge of tissue by the opening of the
            pharyngotympanic tube into the laryngopharynx.

         II. The palatine tonsils are posterior to the palatopharyngeal arch.
 

13.     I. Part of the tensor veli palatini arises from the cartilagenous portion of the
            pharyngotympanic tube.

         II. Fibers from the tensor veli palatini loop around the pterygoid hamulus
            and insert into the soft palate.
 

14.     I. Part of the palatopharyngeus runs from the hard palate to the pharyngeal
            constrictors.

         II. The palatoglossus muscle elevates the rear of the tongue.
 

15.     I. The thyroid cartilage can be found at about the level of C4.

         II. The arytenoid cartilage is superior to the cricoid cartilage.
 

16.     I. The thyrohyoid membrane is the best place to do a tracheotomy on a human.

         II. Unlike the thyroid cartilage, the cricoid cartilage is a ring structure.
 

17.     I. Both the vestibular and vocal ligaments are attached to the arytenoid cartilage.

         II. The vestibular ligament is more lateral in the larynx than the vocal ligament.
 

18.     I. The space between the two vocal folds is called the glottis.

         II. The piriform recess is the space between the vestibular folds and the vocal folds.
 

19.     I. Contraction of the cricothyroid muscle will increase the tension on the
            vestibular folds.

         II. Contraction of the interarytenoid muscles will adduct the vocal folds.
 

20.     I. The posterior cricoarytenoid muscle is innervated by the external branch
            of the superior laryngeal nerve.

         II. The thyroarytenoid muscle can both adduct and decrease the tension
            of the vocal ligaments.
 

21.     I. The posterior cricoarytenoid muscle can abduct the vocal ligaments.

         II. The superior thyroid artery penetrates the thyrohyoid membrane.
 

22.     I. The recurrent laryngeal nerve innervates the thyroarytenoid muscles.

         II. The inferior laryngeal artery, which is a branch from the carotid artery,
            supplies the region of the larynx above the vocal folds.
 

23.     I. Cutting both left and right recurrent laryngeal nerves would result in total
            sensory loss of the larynx.

         II. The isthmus of the thyroid gland is usually inferior to the cricoid cartilage.
 

24.     I. Occlusion of the left subclavian artery may lead to ischemia in the majority
            of the left thyroid lobe.

         II. The superior and middle thyroid veins drain into the external jugular while
            the inferior thyroid vein drains into the brachiocephalic vein.
 

25.     I. A typical person will have 4 parathyroid glands located on the anterior
            side of the thyroid gland.

         II. The primary blood supply for the parathyroid glands are the inferior thyroid arteries.
