The frontal muscle is a part of which structure?

1. Dermis

2. Epicranius

3. Forehead

4. Scalp

The correct answer is: Epicranius

The frontal muscle is part of the epicranius, which is a muscle that covers the upper part of the skull. The epicranius consists of two main parts: the frontalis muscle at the forehead and the occipitalis muscle at the back of the head. The frontalis muscle is responsible for raising the eyebrows and creating horizontal wrinkles on the forehead. Given this relationship, identifying the structure that includes the frontal muscle as part of the epicranius clarifies its anatomical placement and function as a component of the scalp's musculature. While options like the dermis or forehead may relate to the area where the frontal muscle functions, they do not represent the actual muscle structure itself. The scalp generally covers a broader area but does not specify the muscle component as accurately as the epicranius does.
