Nasal Cavity & Paranasal Sinuses
This is the largest of all the paranasal sinuses.
What is the maxillary sinus?
This portion of the pharynx contains the adenoids.
What is the nasopharynx?
This is the largest cartilage of the larynx.
What is the thyroid cartilage?
This cranial nerve innervates the sternocleidomastoid muscle.
What is CN XI (Accessory nerve)?
This is the largest part of the brain and consists of two hemispheres.
What is the cerebrum?
Most paranasal sinuses drain directly into this nasal passage.
What is the middle meatus?
This tube connects the middle ear to the nasopharynx.
What is the auditory (Eustachian/pharyngotympanic) tube?
This muscle is the only intrinsic laryngeal muscle supplied by the superior laryngeal nerve.
What is the cricothyroid muscle?
This nerve arises from C3–C5 and supplies the diaphragm.
What is the phrenic nerve?
These grooves separate the gyri of the cerebrum.
What are sulci?
The nasolacrimal duct empties into this part of the nasal cavity.
What is the inferior meatus?
The palatine tonsils lie between these two arches.
What are the palatoglossal and palatopharyngeal arches?
This space lies between the true vocal folds.
What is the rima glottidis?
This artery is the first branch of the external carotid artery.
What is the superior thyroid artery?
This structure connects the right and left cerebral circulations at the base of the brain
What is the Circle of Willis?
These four bones form the roof of the nasal cavity from anterior to posterior.
What are the nasal, frontal, ethmoid, and sphenoid bones?
This structure forms the opening between the oral cavity and oropharynx.
What is the oropharyngeal isthmus?
The cavity of the larynx is divided into three portions by these structures.
What are two horizontal folds?
These three structures are enclosed within the carotid sheath.
What are the common/internal carotid artery, internal jugular vein, and vagus nerve?
These are the three layers of meninges surrounding the brain.
What are the dura mater, arachnoid mater, and pia mater?
This opening receives drainage from the sphenoid sinus.
What is the sphenoethmoidal recess?
This recess of the laryngopharynx guides food around the laryngeal opening during swallowing.
What is the piriform recess?
This laryngeal muscle is the primary abductor of the vocal folds.
What is the posterior cricoarytenoid muscle?
This artery gives off eight branches in the neck.
What is the external carotid artery?
This sinus drains posteriorly into the confluence of sinuses.
What is the superior sagittal sinus?
