Pulsations of The Tracheal Wall

So called windpipe (the trachea) extends from the level of C6 vertebra to its point of bifurcations between T5-T7 vertebra. We divide it into cervical and mediastinal trachea. The total length is between 9 to 15 cm and there are 15-20 C-shaped tracheal rings. The aorta’s arch is initially anterior to the lower trachea and then immediately superior to the left main bronchus on its left side. There is a difference in a length of a right (about 2.5 cm) and the left (about 5.0 cm) bronchus. The right one is a commoner site for inhaled foreign body to be impacted because it is shorter, wider and more vertical. The left bronchus gives an impression as an indentation when seen during oesophagoscopy because is located anteriorly to the oesophagus. In this video we can see the pulsations of the tracheal wall due to its intimate closeness to the ascending and arch of aorta anteriorly.
