Final answer:
The voice box or Adam's apple is the larynx, a cartilaginous structure located between the pharynx and the trachea, containing the vocal cords necessary for sound production.
Step-by-step explanation:
The voice box, or Adam's apple, is the larynx, a cartilaginous structure that connects the pharynx to the trachea and contains the vocal cords that are essential for producing vocal sounds. The larynx is composed of several pieces of cartilage, including the large thyroid cartilage which includes the laryngeal prominence known as the Adam's apple, the epiglottis, and the cricoid cartilage. The Adam's apple is typically more prominent in males and is a key component in the production of speech and regulation of airflow during breathing.
