What is the Vastus Lateralis Muscle?

The vastus lateralis muscle is one of the four components of the quadriceps femoris group, located on the lateral side of the thigh. It plays a crucial role in extending the knee and is essential for activities such as walking, running, and standing up from a seated position. This muscle is particularly significant in nursing, especially when it comes to administering intramuscular injections.
