By injection refers to a method of introducing a substance into the body, usually through a needle or syringe, directly into a specific area or into a bloodstream. This method allows for rapid and precise delivery of the substance, ensuring its immediate availability for absorption or distribution throughout the body.
In medical contexts, "by injection" often refers to the administration of medications, vaccines, or other therapeutic agents. The substance to be injected can include liquids, solutions, suspensions, or powders that are dissolved or reconstituted prior to injection. The injection can be performed into various sites, depending on the desired target area, such as intramuscular, subcutaneous, intravenous, intradermal, or intra-articular injection.
By injection bypasses the digestive system, allowing the substance to avoid the processes of absorption and metabolism that may affect its effectiveness or bioavailability. This route of administration provides a more direct route to the bloodstream, allowing for immediate drug action and avoiding potential degradation in the gastrointestinal tract.
By injection can also refer to procedures, such as diagnostic or therapeutic injections, that involve the introduction of contrast agents, dyes, anesthetics, or other substances for specific purposes. These injections may be guided by imaging techniques such as ultrasound, X-ray, or computed tomography (CT) to ensure accurate placement.
Overall, the term "by injection" describes a method of delivering substances directly into the body, often used in medical settings to provide fast and effective results.
The phrase "by injection" does not have a distinct etymology of its own as it is a combination of two separate words: "by" and "injection". Here is the etymology of each word:
- "By": This word originated from Old English "bi" and can be traced back to the Proto-Germanic word "*bi" meaning "near" or "by the side of". It was also influenced by Old Norse "bi" and Old Frisian "by". Over time, the word developed various meanings including "through", "with the help of", or to indicate method or agency.
- "Injection": This word comes from Latin "injectio" derived from the verb "injicere", which is a combination of the prefix "in-" meaning "into" and the verb "jacere" meaning "to throw".
