Explanation: The nasolacrimal duct descends from the lacrimal sac and opens beneath the inferior nasal concha in the inferior meatus.

• A. Superior meatus
• B. Middle meatus
• C. Inferior meathus
• D. Spheno- ethmoidal recess

Explanation: The frontal sinus drains through the frontonasal duct into the ethmoidal infundibulum and then the middle meatus.

• A. Pseudo stratified columnar
• B. stratified squamous
• C. Simple columnar
• D. Cuboidal epithelium

Explanation: The true vocal folds are lined by stratified squamous nonkeratinized epithelium because they undergo repeated friction and vibration.

• A. Sinus of morgangini
• B. Between thyropharyngeus and crico- pharyngeus
• C. Pyriforma fossa
• D. Pharyngeal recess

Explanation: The pharyngeal wall is weakest at Killian's dehiscence, a gap between the thyropharyngeus and cricopharyngeus parts of the inferior…

• A. Alveolar periosteum
• B. Periosteum
• C. Mucoperiosteum
• D. An aponeurosis

Explanation: Posteriorly, the hard palate continues into the soft palate, whose fibrous skeleton is the palatine aponeurosis.

• A. Pyriform recess
• B. Pharyngeal recess
• C. Pharyngeal tonsil
• D. Salpingopharyngeal fold

Explanation: The nasopharynx contains structures such as the pharyngeal recess, pharyngeal tonsil and salpingopharyngeal fold.

• A. Lateral pterygoid
• B. Buccinator
• C. Superior constrictor
• D. Medial pterygoid

Explanation: The pterygomandibular raphe gives attachment anteriorly to the buccinator and posteriorly to the superior constrictor.

• A. Lies on superior constrictor
• B. Lymph from it drains in the deep cervical lymph nodes
• C. Has sensory innervation from vagus
• D. Is a derivative of the second pharyngeal arch

Explanation: The middle constrictor is derived mainly from the fourth and sixth pharyngeal arches, not the second arch.

• A. Infundibulum
• B. Summit of infundibulum
• C. Bulla ethmoidalis
• D. Hiatus semilunaris

Explanation: The maxillary sinus drains into the middle meatus through the hiatus semilunaris, usually via the ethmoidal infundibulum.

• A. palatine tonsils
• B. Pharyngeal tonsils
• C. Tubal and lingual tonsils
• D. Post auricular nodes

Explanation: Waldeyer’s ring is a circle of lymphoid tissue formed by the pharyngeal, tubal, palatine and lingual tonsils.

• A. It opens into oropharynx
• B. Supplied by IX nerve
• C. Lined stratified squamous epithelium
• D. It is cartilaginous throughout its length

Explanation: The pharyngotympanic tube has sensory innervation through the tympanic branch of the glossopharyngeal nerve.

• A. Style pharyngeus
• B. Palatopharyngeus
• C. Superior constrictor
• D. Middle constrictor

Explanation: Stylopharyngeus is the only pharyngeal muscle supplied by the glossopharyngeal nerve, whereas the remaining pharyngeal muscles are…

• A. Jugulo omohyoid node
• B. Jugulo digastric node
• C. Submental node
• D. Upper cervical node

Explanation: Palatine tonsillar lymph chiefly drains to the jugulodigastric node, which is therefore called the tonsillar node.

• A. The opening of auditory tube is located in the lateral wall of naxopharynx
• B. The soft palate is at the level of separation of nasopharynx and the oropharynx
• C. The pharynx is continuous with the esophagus at the level of sixth cervical vertebrae
• D. The afferent limb of the gag reflex is 10th cranial nerve; the efferent limb is IX cranial nerve

Explanation: The gag reflex has an afferent limb through the glossopharyngeal nerve and an efferent limb through the vagus nerve.

• A. Posterior ethmoidal
• B. Posterior superior
• C. Sphenoidal
• D. Infratemporal

Explanation: The sphenoidal sinus receives sensory supply from the posterior ethmoidal nerve, a branch of the ophthalmic division of the trigeminal…

• A. Maxillary sinus
• B. Frontal sinus
• C. Sphenoidal sinus
• D. Ethmoidal sinus

Explanation: The maxillary sinus begins as an evagination of the nasal sac during fetal development, making it the earliest developing paranasal sinus.

• A. Palatoglossus and palatopharyngeus
• B. Uvula
• C. Mucous membrane and muscles
• D. All of the above

Explanation: The soft palate contains mucous membrane, a muscular layer including palatoglossus and palatopharyngeus, and the uvula as its midline…

• A. Cricohyoid
• B. Cricothyroid
• C. Arytenoid
• D. Aryepiglotticus

Explanation: The recurrent laryngeal nerve supplies all intrinsic laryngeal muscles except the cricothyroid.

• A. Posterior cricoarytendoids
• B. Transverse arytenoids
• C. Cricothyroid
• D. All of the above

Explanation: The posterior cricoarytenoid muscles rotate the arytenoid cartilages laterally and are the only muscles that abduct the vocal folds.
