Submandibular Region

1. 4- The submandibular ganglion contains preganglionic parasympathetic axons from which cranial nerve?

III (oculomotor)
V (trigeminal)
VII (facial)
IX (glossopharyngeal)
X (vagus

2. 2-A 46-year-old female patient comes to the emergency department complaining of pain in the area just below her mandible on the right side of her face. She says that the pain is particularly severe when she eats. The area of the submandibular gland is tender and swollen, as is the area in the floor of her mouth lateral to the tongue. You suspect a stone in the submandibular duct, and a plain film radiograph shows a density in that region consistent with a stone. In order to remove the stone, the duct must be incised in the floor of the mouth. What nerve, that loops around the duct, is in danger in such an incision?

Chorda Tympani
Glossopharyngeal
Hypoglossal
Internal branch of the superior laryngeal
Lingual

10. 8- The styloid process: a. gives attachment to the styloglossus muscle near its tip. b. gives attachment to a muscle supplied by the vagusl nerve. c. gives attachment to a muscle supplied by the facial nerve. d. gives attachment to a muscle supplied by the glossopharyngeal nerve.
