The frontal sinuses are not present at birth. They begin to develop in the first few years of life, but they are not fully mature until after adolescence. The sphenoid, maxillary, and ethmoid sinuses are present at birth, though they are underdeveloped and similarly do not mature fully till late childhood or adolescence.

Which of the following maintains the lumen of the trachea?
Which of the following maintains the lumen of the trachea?

The lumen of the trachea is maintained by the tracheal cartilages, a set of approximately 20 separate c-shaped rings of hyaline cartilage. The non-continuous cartilage allows for greater flexibility during inspiration and expiration.
