The muscle that covers the scalp is the epicranius, which is also known as the occipitofrontalis muscle. This muscle is significant because it is involved in facial expressions and plays a key role in raising the eyebrows and creating forehead movements. The epicranius consists of two parts: the frontalis, which is located at the front of the head, and the occipitalis, located at the back of the head. Together, these parts function as a single muscle that allows for various movements of the scalp.

The other options refer to different muscles with distinct functions in the facial area. The procerus is involved in frowning and is located between the eyebrows. The zygomaticus muscle helps with smiling and is situated in the cheek area, while the buccinator is involved in actions like chewing and blowing, located in the cheek region. Each of these muscles serves a unique purpose, but they do not cover the scalp as the epicranius does.
