The trachea runs from the throat (in the the head) down the neck to the lungs (chest). It is the firm tube you can feel in the midline of your neck.
The trachea itself is made of ligaments and cartilage, but there are muscles in the region around the trachea.

The trachea is derived from the endoderm germ layer. Specifically, it develops from the foregut region of the endoderm during embryonic development. The surrounding mesoderm contributes to the cartilage and connective tissue structures of the trachea.
The paratracheal region is located next to the trachea in the neck. It is a common location for lymph nodes and can be important for the staging of certain cancers or infections.
The subcarinal region is located in the lower part of the trachea where it divides into the left and right main bronchi. The aortopulmonary (AP) window region is the space between the ascending aorta and pulmonary trunk.
There's the mouth, the pharynx, the larynx (voice box), the trachea, and the esophagus (for food).
The singular for trachea is "trachea". The plural is "tracheae".
The lungs, trachea, and heart do not reside within the mediastinum. They lie outside this region.
