All of the neck muscles except the cricothyroid muscle.
No, the trachea does not have skeletal muscle. Instead, it is composed of smooth muscle, cartilage, and connective tissue. Smooth muscle allows for involuntary control of the trachea's diameter and airflow.
The trachea is mostly cartilage, surrounded by smooth muscle, which is an autonomic muscle type, meaning we can't consciously control it
It's a "flap" that covers either the trachea or esophagus. It prevents you from choking. When you eat, it covers the trachea so food will go down the esophagus and not the windpipe (trachea). If food gets down your trachea, you will choke.
The trachea itself is made of ligaments and cartilage, but there are muscles in the region around the trachea.

epiglottis
The epiglottis protects the trachea from food.
The epiglottis covers the opening to the trachea when swallowing - thereby preventing food/drink entering the trachea and lungs.
Several protective mechanisms prevent the aspiration of food into the trachea. These include the epiglottis, which covers the trachea during swallowing, the coordination of muscle contractions in the throat to direct food into the esophagus, and the cough reflex to expel any foreign material that might enter the trachea.

The thyroid gland is located anterior to the trachea. The parathyroid glands are located within the thyroid gland.
