Which of the following structures is not found in the mediastinum?

A. Pain over the eyes is associated with sinusitis in the frontal sinuses (located above the eyes), not the maxillary sinuses.
B. The maxillary sinuses are located in the cheeks, so pain related to maxillary sinusitis is typically felt in this area.
C. Pain over the ears is not typically associated with sinusitis; it is more common with ear infections or other middle ear conditions.
D. Pain above the eyebrows is typically related to frontal sinusitis, not maxillary sinusitis.

A. Bronchodilators are medications specifically designed to relax the muscles around the airways, making it easier to breathe by increasing airflow. They are commonly used in conditions like asthma and chronic obstructive pulmonary disease (COPD).
B. Doxycycline is an antibiotic used to treat bacterial infections. It has no direct effect on airway muscles or airflow.
C. ACE inhibitors are used primarily to treat high blood pressure and heart failure. They do not act on the airways and are not used to improve airflow.
D. Anti-androgen therapy is used to reduce levels of male hormones, typically in the treatment of prostate cancer or hormone-sensitive conditions. It has no role in bronchodilation or respiratory therapy.
