organs are located within the thorax and consist of trachea, bronchial tree, and lungs

? Single laryngeal cartilages-the three largest cartilages: the thyroid cartilage, the epiglottis, and the cricoid cartilages ? The paired laryngeal cartilages-three pairs of smaller cartilages: arytenoid, corniculate, and cuneiform cartilages

Question 5: What are the two pairs of fold formed by the larynx?

Answer:

vestibular folds (false vocal cords); true vocal chords

Question 6: Where is the medial surface of the Lungs?

Answer:

facing the mediastinum

Question 7: What is the base of the Lungs?

Answer:

inferior surface of lung that rests on diaphragm

Question 8: What is the function of the thorax?

Answer:

to bring about inspiration and expiration

Question 9: What is the shape of the posterior surface?

Answer:

round

Question 10: What are the two main functions of the larynx?

Answer:

Larynx functions as part of the airway to the lungs and produces the voice

Question 11: What are anterior nares?

Answer:

external openings to the nasal cavities, open into the vestibule

Question 12: The oropharynx contains two pairs of organs, what are they?

Answer:

teh palatine tonsils (most commonly removed) and the lingual tonsils (rarely removed)

Question 13: What is the sequence of air through nose into pharynx?

Answer:

anterior nares to vestibule to all three meati simultaneously to posterior nares Question 14: Where are the Pharyngeal tonsils located and what are they called when they become enlarged?

Answer:

located in the nasopharynx, called adenoids when they become enlarged Question 15: The nose, which is the passageway for air to travel to and from the lungs, has three special functions. What are they?

Answer:

filters the air, aids speech, and makes possible the sense of smell

Answer:

lies against ribs

Question 19: What is the internal nose?

Answer:

the nasal cavity that lies over the roof of the mouth, separated by palatine bones

Question 20: What is the cleft palate?

Answer:

palatine bones fail to unite completely and only partially separate the nose and the mouth, producing difficulty in swallowing

Question 21: What distribute air to lung's interior?

Answer:

Bronchi and bronchioles

Question 22: What is the septum?

Answer:

separates nasal cavity into a right and a left cavity; consists of four structures: the perpendicular plate of the ethmoid bone, the vomer bone, the vomeronasal cartilages, and the septal nasal cartilage

Question 23: How does the trachea divide to become the bronchi and alveoli?

Answer:

Lower end of trachea divides into two primary bronchi, one on right and one on left, which enter lung and divide into secondary bronchi that branch into bronchioles, which eventually divide into the alveolar ducts

Question 24: What are dust cells?

Answer:

are phagocytic cells (macrophages) found in the alveolar space

Answer:

Located between root of tongue and upper end of trachea

Question 26: What are alveoli?

Answer:

the primary gas exchange structures

Question 27: What are the muscles of the larynx?

Answer:

Intrinsic- both insert and originate w/in the larynx; Extrinsic- insert in larynx but originate on some other structure
