The muscle that forms the lateral aspect of the thigh is the tensor fasciae latae (TFL). It is a small, strap-like muscle located on the outer side of the thigh and plays a crucial role in stabilizing the hip and knee during movement. The TFL works in conjunction with the iliotibial band (IT band), which runs down the lateral side of the thigh.
The Sartorius muscle - the longest muscle in the human body - is a long thin muscle that runs down the length of the thigh. Its upper portion forms the lateral border of the femoral triangle.

The iliotibial (IT) band is the dense fascial band that runs from the ilium (pelvis) to the tibia on the lateral aspect of the thigh. It plays a role in stabilizing the knee during functional movements like walking and running.
Usually they are administered in the upper outer thigh.
The two anterior aspects of the upper thigh are the quadriceps femoris muscle group and the sartorius muscle. The quadriceps femoris group is a large muscle that covers the front of the thigh and is responsible for extending the knee joint. The sartorius muscle is the longest muscle in the body and helps with flexing the hip and knee joints and rotating the thigh.
Gluteus Maximus
The name 'rectus' means straight while femoris refers to the thigh. So, it refers to the straight muscle of the thigh, which is a member of the quadriceps femoris.
The Epi Pen can also go into your deltoid muscle (the largest muscle part of your arm) because an Epi Pen is an IM (Intra-muscular) injection. On the lateral portion of your thigh, you have a large muscle that can be easily accessed and can absorb the medication appropriately and quickly.
Your thigh muscle is called your Quadricep.
The anatomical term for the outer side of the left thigh is the lateral side of the left thigh.
The left hip and upper leg region would be in the lateral aspect of the lower back region and posterior aspect of the left thigh region.
