What does "sc" signify in medical terms?

In medical terminology, "sc" signifies "subcutaneous." This term refers to the layer of tissue beneath the skin and is often used to describe the method of administering medications, particularly injections. Subcutaneous injections are delivered into the fatty tissue just under the skin, allowing for the medication to be absorbed slowly into the bloodstream. This route is commonly used for medications such as insulin or certain vaccines, as it provides a gradual absorption rate and can be less invasive than other forms of injection.

Understanding the term "subcutaneous" is essential for pharmacy technicians, as it directly relates to medication administration techniques, patient care, and ensuring the proper routes of delivery for treatments. The other terms, while they may relate to different aspects of medical procedures or anatomy, do not align with the abbreviation "sc" in this context.
