Tracheal Cross-section Using colored pens/pencils, draw the histology Image B from the “Tracheal Cross-section” chart in the space below. Using Image A as a reference, label your drawing with the esophagus, folded mucosa, posterior cartilage, trachealis muscle, trachea, mucosa, submocosa, and thyroid gland.
The trachea is a cartilaginous tubular structure connecting the larynx superiorly and the main bronchi inferiorly ( Figure 1) (2). The lower edge of the cricoid cartilage defines the beginning of...
