QuestionAnswer
Besides the thyroid and cricoid cartilages, name the other cartilages of the larynx. arytenoid, epiglottic, corniculate, cuneiform
Describe the motor innervation (include components innervated) to the larynx. intrinsic muscles except cricothyroid by recurrent laryngeal nerve of CN X; cricothyroid by external branch of the superior laryngeal nerve of CN X
Slit-like opening between the false vocal cords. Rima vestibuli
Fissure separating upper and middle lobes of the right lung. Oblique horizontal
A sharp mucosal covered ridge of the middle meatus. Uncinate process
Name given to parietal pleura over apex of lung. Cupula
Meatus into which the nasolacrimal duct drains. Inferior meatus
Hypertrophied lymphatic components on the roof of the nasopharynx. Adenoids
Internally correspond to alae of the nose; has sweat glands, sebaceous glands and hairs. Vestibule
Swelling in the middle meatus, marks the position of ethmoid air cells. Ethmoid bulla
Besides the aorta, list two structures which can pass through the aortic hiatus. Thoracic duct, azygos vein
What muscle of the larynx is an antagonist to the cricothyroid muscle? Thyroarytenoid
What muscle of the larynx extends from posterior surface of the cricoid lamina to the muscular process of the arytenoids cartilage? Posterior cricoarytenoid
Structure over which the mucosa of the larynx is reflected to form the vestibular fold. Quadrangular membrane
Slit-like opening between the true vocal cords. Rima glottidis
Define a bronchopulmonary segment. Portion of a lung supplied with air from a tertiary bronchus and its branches.
Left lung homologue of middle lobe of right lung. Lingula
Opening of ethmoidal infundibulum into the meatus. Semilunar hiatus
Specific structure responsible for forming the limen nasi. Lower edge of the lateral nasal cartilage
A structure which drains into the inferior meatus. Nasolacrimal duct
Give two landmarks present on the medial surface of the right lung, but not the left. Superior vena cava, azygos vein
The mucosal reflection over the upper edge of the quadrangular membrane of the larynx. Aryepiglottic fold
This structure passes upward from the arch of the cricoid cartilage; on its upper edge it is thickened to form the vocal ligaments. Conus elasticus
Define the root of the lung. The structures which pass through the hilus = bronchi, vessels, nerves, and lymphatics
Name given to the upper part of the dorsum nasi supported by nasal bones. Bridge
Name bony components forming the roof of the nasal cavity. Nasal bone, frontal bone, cribriform plate of ethmoid, body of sphenoid
Specific structure that supports the tracheal bifurcation. Carina
Give two components mentioned in lecture which form the lateral wall of the nasopharynx. Ostia of auditory tubes, pharyngeal muscles
Fissure separating upper and middle lobes of the right lung. Horizontal fissure
Name two structures related to the left side of the thoracic part of the trachea. left recurrent laryngeal n., arch of the aorta, left common carotid a., left subclavian a.
What muscle of the larynx lengthens and tightens the vocal cord, thus increasing pitch? Cricothyroid
What muscle of the larynx inserts on the muscular process of the arytenoid and rotates the cartilage medially, but does not pull the cartilage anteriorly? Lateral cricoarytenoid
Give the term for the space between the true and false vocal cords. Ventricle
Name given to mucosal reflection formed by the lower edge of the quadrangular membrane. Vocal ford
Structure which has a lateral and medial crus to hold open the nostrils. Greater alar cartilage
Into what meatus does the maxillary sinus drain? Middle meatus via infundibulum
Into what meatus does the frontal sinus drain? Middle meatus via frontonasal duct and ethmoidal infundibulum
A ridge within the nasal cavity separating stratified squamous from respiratory mucosa. Limen nasi
What muscle(s) of the larynx act(s) as a sphincter of the laryngeal inlet? Oblique arytenoid and aryepiglottic muscles
What muscle(s) of the larynx is/are not innervated by the recurrent laryngeal n.? Cricothyroid
