Which muscle is located at the nape of the neck and draws the scalp back?

The muscle located at the nape of the neck that draws the scalp back is the occipitalis. This muscle plays a crucial role in the movement of the scalp and is part of the larger group of muscles known as the epicranius or occipitofrontalis.

The occipitalis is specifically responsible for pulling the scalp backward, which can contribute to facial expressions and the overall movement of the scalp. Its action can also influence the appearance of the forehead and can assist in the coordination of movements between the frontalis muscle (located at the forehead) and the occipitalis, allowing for a range of expressions and movements of the head and face.

In contrast, the other muscles listed serve different functions. The orbicularis oculi is primarily involved in closing the eyelids, the corrugator muscle assists with furrowing the brow, and the levator palpebrae superioris primarily elevates the upper eyelid. Understanding the specific roles of these muscles helps in recognizing how they contribute to various facial expressions and movements.
