Advanced Sublingual Gland Quiz

Q1. Why can a sublingual gland mucus leak produce a ranula?

• Extravasated mucus can collect in the floor-of-mouth tissues
• The gland drains into the middle ear
• The gland secretes cerebrospinal fluid
• The gland normally contains an epithelial cyst

Q2. What anatomical relationship explains the typical location of a simple ranula?

• The gland lies deep to the pharyngeal constrictors
• The gland lies inside the parotid fascia
• The gland lies above mylohyoid directly beneath the oral mucosa
• The gland lies within the carotid sheath

Q3. How can a plunging ranula extend into the submandibular region?

• It can pass around or through mylohyoid into the submandibular space
• It enters the neck through the mental foramen
• It travels through the carotid canal
• It descends through the esophageal lumen

Q4. Why is the lingual nerve important during surgery involving the sublingual gland and floor of the mouth?

• It is enclosed within the sublingual ducts
• It supplies motor fibers to all tongue muscles
• It provides the gland's arterial supply
• It lies nearby and carries general sensory plus chorda tympani fibers

Q5. Why can injury to chorda tympani before its parasympathetic fibers synapse reduce sublingual secretion?

• It is the gland's only sensory nerve
• It carries preganglionic facial parasympathetic fibers to the submandibular ganglion
• It is the sympathetic supply from the cervical trunk
• It carries postganglionic glossopharyngeal fibers from the otic ganglion

Q6. Why may a lesion of the submandibular ganglion affect both submandibular and sublingual secretion?

• The ganglion is located inside the parotid gland
• Both glands share the submandibular ganglion as a parasympathetic relay
• Both glands receive secretion fibers only from the vagus
• Both glands are supplied by the otic ganglion

Q7. Why can a large sublingual swelling elevate the tongue?

• The gland lies inside the intrinsic tongue muscles
• The swelling pulls the hyoid directly upward
• Expansion in the sublingual space can displace the tongue upward
• The gland is attached to the tongue apex by a tendon

Q8. Why must the submandibular duct be considered during procedures on the sublingual gland?

• The duct crosses the external acoustic meatus
• The duct lies inside the mandibular canal
• The submandibular duct runs closely along the medial aspect of the gland
• The duct passes through the center of the parotid gland

Q9. Why can defects in mylohyoid alter the spread of sublingual pathology?

• Mylohyoid defects connect the mouth directly to the cranial cavity
• They reroute the parotid duct into the neck
• Mylohyoid defects can connect the sublingual and submandibular spaces
• They open the sublingual gland into the larynx

Q10. Which statement best integrates the anatomy of the sublingual gland?

• It lies in the tonsillar fossa and drains directly into the oropharynx
• It lies above mylohyoid, drains mainly through multiple ducts, and receives facial parasympathetic fibers through the submandibular ganglion
• It lies below mylohyoid, has no ducts, and receives vagal secretomotor fibers
• It lies in the parotid bed, drains through Stensen duct, and receives glossopharyngeal fibers through the otic ganglion
