Large amounts of injectable medication, at least 2 ml or more, are given intramuscularly. Intramuscular (IM) injections are administered into the muscle tissue, which allows for a larger volume of medication to be absorbed more rapidly than subcutaneous or intradermal routes. Common sites for IM injections include the deltoid, gluteus, and vastus lateralis muscles.

The cerebellum is located at the back of the brain, beneath the occipital lobes and behind the brainstem. It plays a crucial role in motor control, particularly in the coordination, precision, and timing of movements. The cerebellum integrates input from the sensory systems, the spinal cord, and other parts of the brain to fine-tune motor activity. It helps maintain balance and posture by coordinating the muscles used for these functions. Damage to the cerebellum can result in loss of coordination (ataxia), tremors, and difficulty with balance and gait.
