Question

question 12 1 pts
the structures that deflect air as it passes through the nose are called:
choanae.
paranasal sinuses.
conchae.
vibrissae.
question 13 1 pts
the lower border of the cavity of the larynx is formed by the:
epiglottis.
cricoid cartilage.
glottis.
thyroid cartilage.
question 14 1 pts
which of the following lists the correct sequence of air as it passes through the nose into the pharynx?
vestibule anterior nares inferior, middle, and superior meatus posterior nares
inferior, middle, and superior meatus nostrils vestibule posterior nares
anterior nares vestibule inferior, middle, and superior meatus posterior nares
anterior nares posterior nares vestibule inferior, middle, and superior meatus

Explanation:

• Question 12: Conchae (also known as turbinates) are the structures in the nose that deflect air. Choanae are the posterior openings of the nasal cavity. Paranasal sinuses are air - filled spaces around the nasal cavity. Vibrissae are the stiff hairs in the nasal vestibule.
• Question 13: The cricoid cartilage forms the lower border of the laryngeal cavity. The epiglottis is a flap that covers the larynx during swallowing. The glottis is the opening between the vocal folds. The thyroid cartilage is the largest cartilage of the larynx but does not form the lower border.
• Question 14: Air enters through the anterior nares (nostrils), then goes to the vestibule, then passes through the inferior, middle, and superior meatus (passages), and finally exits through the posterior nares into the pharynx.

Answer:

• Question 12: conchae
• Question 13: cricoid cartilage
• Question 14: Anterior nares - vestibule - inferior, middle, and superior meatus - posterior nares
