Question

Anatomy Tutorial: Anatomy of the Trachea

Answer 1

note: for the purposes of this tutorial I will only be going over the locations of the components rather than their functions, for memorization purposes

Answer 2

first, divide the trachea into three main components: the hyoid bone (attachment site), the larynx (the voicebox), and the trachea (the windpipe)

Answer 3

the broad blue sections are tracheal cartilages and in between them are the annular ligaments

Answer 4

at the branching point of the primary bronchi, is the carina / internal ridge

Answer 5

the two circular labels are given to the roots of the right and left lung respectively

as usual, R and L designations are given from the perspective of the subject not the observer

Answer 6

now on the left lung the upper branch is the superior lobar bronchus, the lobar bronchus, and the inferior lobar bronchus

unfortunately the divisions on the right side are a bit more complicated than that due to the larger size of the lung

Answer 7

the inferior lobar bronchus is divided into the middle inferior and the inferior bronchus
