Livestock Skillathon: Quality Assurance Practice Test

Injections into muscle tissue are called intramuscular injections. This term describes delivering medication directly into the muscle, where it is absorbed into the bloodstream through the muscle’s rich blood supply. The muscle provides a good site for absorption and can accommodate a moderate volume of medicine, which is why many vaccines and other medications are given this way. It’s different from intravenous injections, which go into a vein for very rapid systemic delivery; subcutaneous injections, which go into the fatty layer just under the skin; and intra-articular injections, which are placed directly into a joint. For livestock, intramuscular administration is common, but proper technique and site selection matter to minimize tissue damage and ensure safety and efficacy.
