An injection into a fatty tissue lying immediately under the skin is called

• A. Intra-articular
• B. Intramuscular
• C. Subcutaneous
• D. Intrathecal

Answer: (C)

Subcutaneous injections target the fatty layer just beneath the skin, known as subcutaneous tissue or the hypodermis. This superficial layer is less vascular than muscle, so medications injected here are absorbed more slowly, making it ideal for drugs like insulin and some anticoagulants that benefit from steadier absorption. The term describes the exact location of the injection: the fatty tissue immediately under the skin, not the muscle, joint, or spinal canal. Intra-articular refers to a joint space, intramuscular to muscle tissue, and intrathecal to the spinal canal around the nerves. So the described injection is subcutaneous.
