Respiration is centrally regulated by the:
Cerebellum
Diencephalon
Cerebral cortex
Brain Stem
The Correct Answer is D
A. The cerebellum is involved in coordinating movement and balance but is not primarily responsible for regulating respiration.
B. The diencephalon is involved in sensory processing and regulation of autonomic functions but does not directly control respiration.
C. The cerebral cortex is involved in voluntary control over breathing (such as when you hold your breath), but the central regulation of breathing is managed by the brainstem.
D. The brainstem (specifically the medulla oblongata and pons) is the primary control center for respiration. It regulates the rate and depth of breathing by responding to levels of oxygen and carbon dioxide in the blood.

Correct Answer is B
Explanation
A. Elevated WBC count and increased serum potassium are not common side effects of bronchodilators. These might be seen in other conditions or medications, but not typically with bronchodilators.
B. Nervousness, palpitations, and tremors are common side effects of bronchodilators, particularly beta-agonist bronchodilators like albuterol. These symptoms occur because bronchodilators stimulate beta receptors in the body, leading to increased heart rate and stimulation of the nervous system.
C. Urinary retention and gynecomastia are more commonly associated with other medications, such as anticholinergics or certain hormonal treatments, not bronchodilators.
D. Steven Johnson Syndrome is a rare and severe skin reaction that can occur with certain medications, but it is not a common side effect of bronchodilators.
