rior triangle contains the occipital and supra-clavicular (omoclavicular or subclavian) trian-gles (Moore, p 1004).
109. (E) The posterior cervical triangle contains thesplenius capitis, levator scapulae, middle sca-
lene, and posterior scalene (Moore, p 1004).
110. (A) The suprahyoid muscles are the mylo-hyoid, geniohyoid, stylohyoid, and digastricmuscles (Moore, p 1016).
111. (A) The mylohyoid and anterior belly of thedigastric are innervated by the trigeminal nerve(Moore, p 1016).
112. (C) The anterior vertebral muscles are the lon-
gus colli, longus capitis, rectus capitis anterior,and rectus capitis lateralis (Moore, p 1026).
113. (A) The only lateral vertebral muscle that isinnervated by dorsal rami is the splenius capi-tis (Moore, p 1026).
114. (A) There is NOT a middle thyroid artery, butthere is a middle thyroid vein (Moore, pp 10301033).
115. (B) Arytenoids, corniculate, and cuneiformcartilages are paired, whereas the thyroid, cri-coid, and epiglottic are single (Moore, p 1038).
116. (C) All intrinsic laryngeal muscles are inner-vated by the recurrent laryngeal nerve exceptthe cricothyroid, which is innervated by theexternal laryngeal nerve (Moore, p 1045).
117. (A) The cricothyroid stretches and tenses thevocal fold (Moore, p 1045).
118. (E) The posterior cricoarytenoid abducts thevocal fold (Moore, p 1045).
119. (C) The internal laryngeal nerve is the sensorynerve of the larynx (Moore, p 1048).
120. (A) The pharyngeal tonsils are commonlyreferred to as the adenoids (Moore, p 1051).
121. (E) The salpingopharyngeus is innervated bythe glossopharyngeal nerve. The three con-
strictors, palatopharyngeus, and salpingopha-ryngeus are innervated by the cranial root ofthe accessory nerve (Moore, p 1056).
122. (A) The superior constrictor inserts on themedian raphe of the pharynx and the pharyn-
geal tubercle on the basilar part of the occipitalbone (Moore, p 1056).
123. (B) The ascending palatine artery, levator velipalatini, and pharyngotympanic tube passthrough the gap between the superior con-strictor and the skull (Moore, pp 1055, 1058).
124. (A) The glossopharyngeal nerve, stylopharyn-geus, and stylohyoid ligament pass throughthe gap between the superior and middle con-
strictors (Moore, p 1058).
125. (A) The superior laryngeal artery and vein andthe internal laryngeal nerve pass through thegap between the middle and inferior constric-tors (Moore, p 1058).
126. (D) The inferior laryngeal artery and recurrentlaryngeal nerve pass through the gap inferiorto the inferior constrictor (Moore, p 1058).
127. (A) A Le Fort I fracture is a horizontal fractureof the maxillae (Moore, p 836).
128. (B) The mastoid processes are absent at birth.Therefore, the facial nerves are close to the sur-face when they emerge from the stylomastoidforamina and may be injured during delivery(Moore, p 847).
129. (D) The site of anesthetic injection to block theinferior alveolar nerve is the mandibular fora-men (Moore, p 861).
130. (E) A lesion of the zygomatic branch of CN VIIwould cause paralysis of the orbicularis oculiand therefore a drooping of the lower eyelid.Subsequently, tears would fail to spread overthe cornea, resulting in a corneal scar and there-fore impaired vision (Moore, p 864).
131. (C) The facial veins make clinically importantconnections with the cavernous sinus through
