What hormonal function is associated with having a "calci-tone it down" mnemonic?

• A. Increase blood glucose
• B. Decrease blood calcium levels
• C. Enhance metabolism
• D. Inhibit inflammation

Answer: (B)

The mnemonic "calci-tone it down" refers to the function of the hormone calcitonin, which is secreted by the parafollicular cells (or C cells) of the thyroid gland. This hormone plays a crucial role in regulating calcium levels in the blood. Specifically, calcitonin's primary function is to decrease blood calcium levels. It does this by inhibiting osteoclast activity in the bones, which reduces the release of calcium from bone into the bloodstream. Additionally, calcitonin promotes the excretion of calcium by the kidneys, further contributing to lower serum calcium levels. This mnemonic effectively captures the essence of calcitonin's action, allowing students to remember that it is associated with reducing rather than increasing calcium levels in the body. Understanding this function is essential in the context of calcium homeostasis and the interactions of various hormones involved in maintaining mineral balance.
