It's not entirely hollow, but yes, it is a organ that sits atop the trachea
The larynx is located at the top of the trachea or windpipe. In the larynx, the vocal folds, commonly known as the vocal cords, close tightly when swallowing to prevent any food or drink from entering the trachea and lungs.
The thin flaps on top of your windpipe are called the vocal cords. These cords vibrate when air passes through them, producing sound. They are essential for speaking and singing.
The voice box, also known as the larynx, is located in the neck at the top of the windpipe (trachea). It houses the vocal cords, which vibrate to produce sound.
From the anatomy ... the portion of a hollow organ opposite or farthest from its opening.
The Cricoid cartilage. The larynx is the organ at the end of the upper respiratory tract (responsible for preventing food and drink going down the airway and contains the vocal chords) the trachea is the first organ in the lower respiratory tract (the windpipe). The thyroid cartilage is located around the mid to lower larynx and the cricoid cartilage links the bottom of the larynx to the top of the trachea. The epithelial cells (internal surface) change from mostly squamous cells (smooth lining) to columnar epithelial cells (many with microscopic hairlike protrusions called cilia).
The windpipe is in the chest,superior(laying on top) of the esophogus.The formal name for it is the trachea.
The glottis opens into the windpipe and is responsible for the production of sound. While the epiglottis is a cartilaginous flap on top of the glottis that prevents the food from entering the larynx. The main difference between glottis and epiglottis is their function and structure.
The human voice box is also known as the larynx. This organ can be found at the top of the neck and also houses the vocal chords, which are essential in speech.
The voicebox allows you to speak. It is a hollow, tubular organ situated at the top of your windpipe and its two main jobs are to stop food from entering the airways and allow you to speak. The voicebox or larynx works by manipulating the air that passes over it. As the air enters the voicebox, the vocal cords expand and contract, working together with the lips, tongue, teeth AND throat. The shorter your vocal cords, the higher the sound you produce. The mouth is also very important. When you whisper, you can make sounds with the help of the voicebox. The air blows through your mouth and creates various vibration patterns
