Laryngeal Muscles Quiz

A swimmer develops cough during otoscopy. Explanation states the nerve supplying the external auditory meatus triggers this response. Which specific branch is implicated?

• Auriculotemporal nerve

• Great auricular nerve

• Auricular branch of vagus

• Chorda tympani

The right kidney lies slightly lower as it relates only to which rib?

• 10th rib

• 11th rib

• 12th rib

• No rib relationship

Which site best matches the anatomical location referred to as "Coffin's corner," known for difficulty of clinical detection due to anatomical obscurity?

• Posterosuperior to soft palate

• Behind lower 3rd molar and anterior to ascending ramus

• Infratemporal fossa near maxillary tuberosity

• Behind tonsillar fossa and below superior constrictor

Which action most strongly identifies the cricothyroid muscle?

• Relaxation and thickening of cords

• Lengthening and tension of cords for high pitch

• Abduction of vocal cords

• Closure of posterior glottis

Identify the nerve responsible for innervating the majority of laryngeal muscles

• External laryngeal nerve

• Recurrent laryngeal nerve

• Accessory nerve

• Lingual nerve

Maxillary artery explanation states third part branches supply palate. Which is best inferred?

• Greater and lesser palatine arteries arise from descending palatine artery

• Lesser palatine arteries arise from middle meningeal

• Infraorbital artery ends as posterior palatine

• Buccal artery supplies palatal vault

Origin of trigeminal nerve states origin . Which inference is correct?

• It originates between pons and medulla

• Origin is strictly from medulla

• Sensory root emerges at level of pons

• Motor root emerges at occipital condyle

Zenker’s diverticulum explanation identifies a weak zone between two muscular components. Which correctly reflects the boundaries?

• Cricothyroid above, thyrohyoid below

• Thyropharyngeus above, cricopharyngeus below

• Stylopharyngeus above, cricothyroid below

• Sternothyroid above, omohyoid below

A patient has difficulty swallowing due to pouching of pharyngeal mucosa. Based on explanations, what mechanism best explains it?

• Excess relaxation of cricopharyngeus

• Failure of cricopharyngeus relaxation producing high intraluminal pressure

• Hypercontractility of thyropharyngeus

• Weak stylopharyngeus attachment

Retropharyngeal space explanation mentions it lies between two fascial layers. Which accurately reflects its definition?

• Buccopharyngeal fascia and sternocleidomastoid sheath

• Prevertebral fascia and carotid sheath

• Alar fascia and true prevertebral fascia

• Visceral fascia and alar fascia
