A patient with chronic nasopharyngeal obstruction due to adenoid hypertrophy is at high risk of ear complications. Anatomically, this is because...
The nasopharynx communicates directly with the paranasal sinuses
The opening of the auditory (Eustachian) tube empties into the nasopharynx
The tensor veli palatini muscle that opens the tube originates from the nasopharynx
Sensory innervation of the ear and the nasopharynx is both from the trigeminal nerve
Lymphatic drainage of the ear drains to the pharyngeal tonsil
During swallowing (deglutition), the food bolus is propelled from the oropharynx to the esophagus by sequential contraction of the pharyngeal constrictor muscles. The correct sequence is...
Superior → middle → inferior
Inferior → middle → superior
Middle → superior → inferior
Superior and middle together, then inferior
Contraction occurs simultaneously in all three
A post-stroke patient reports dysphagia and frequent choking. The lesion most likely affects the motor innervation of the pharyngeal muscles, which primarily comes from...
Trigeminal nerve (CN V)
Facial nerve (CN VII)
Glossopharyngeal nerve (CN IX)
Pharyngeal branch of the vagus nerve (CN X)
Hypoglossal nerve (CN XII)
The palatine tonsil receives its principal arterial supply from the...
Ascending pharyngeal artery
Facial artery (tonsillar branch)
Lingual artery
Maxillary artery
Superior thyroid artery
In the pharyngeal phase of swallowing, closure of the nasopharynx to prevent nasal regurgitation occurs due to contraction of...
Superior pharyngeal constrictor
Palatopharyngeus muscle
Tensor and levator veli palatini
Muscles of the soft palate (especially levator veli palatini)
All of the above contribute
The laryngeal cartilage that forms a complete ring and serves as the landmark for emergency cricothyrotomy is the...
Thyroid cartilage
Cricoid cartilage
Arytenoid cartilage
Corniculate cartilage
Epiglottis
A patient has hoarseness and a weak voice after thyroid surgery. Laryngoscopy shows the left vocal cord in a paramedian position (partially closed). The most likely lesion is in the...
Left recurrent laryngeal nerve
Left superior laryngeal nerve
Left vagus nerve at the jugular foramen
Left glossopharyngeal nerve
Cervical sympathetic chain
The muscle that, when it contracts, tenses the vocal cords and thus increases pitch is the...
Thyroarytenoid muscle
Vocalis muscle
Cricothyroid muscle
Oblique arytenoid muscle
Posterior cricoarytenoid muscle
The laryngeal prominence (Adam’s apple) is formed by the...
Junction of the two laminae of the cricoid cartilage
Junction of the two laminae of the thyroid cartilage
Superior tip of the epiglottis
Prominent arytenoid cartilage
Thyrohyoid membrane
During normal quiet respiration, the position of the rima glottidis is...
Completely closed
Slightly open (abducted)
Moving to produce sound
Partially closed as in phonation
Dependent on the phase of inspiration/expiration
