Pharmacology Quiz: The Endocrine System!

This is a pharmacology quiz about the Endocrine System! The endocrine system is charged with making hormones that control moods, organs, and growth. The endocrine glands are divided into the thyroid gland and the adrenal glands. There are a lot of issues that can arise in the system and prevent it from functioning correctly. There are also different prescribed drugs, and this quiz will test how well you know them and their effect.

  • 15. 
    Sulfonylureas and meglitinides both work by inhibiting the outflux of potassium ions from the beta cells in the pancreas. This then causes depolarization of the cell, leading to the release of insulin. They differ from each other in the following way.
    • A.

    • C. 

      Meglitinides only cause partial depolarization of the cell, resulting in less insulin release
