Final answer:
The adult larynx is located in the thoracic cavity, as it is part of the respiratory system, which is housed within the thoracic cavity of the anterior body cavities.
Step-by-step explanation:
The adult larynx is located in the thoracic cavity, making an option a) the correct answer to the question. The thoracic cavity is part of the anterior (ventral) cavity, which is further divided into the thoracic and abdominopelvic cavities. The thoracic cavity, which is superior to the abdominopelvic cavity, is encased by the rib cage and contains the lungs, heart, and the mediastinum where the larynx is situated.
The diaphragm separates the thoracic cavity from the abdominopelvic cavity, with the latter being divided into the abdominal and pelvic cavities. As for Review Question 9, the cranial cavity contains a component of the central nervous system, making option c) the correct choice.
