The occipitalis muscle is a small muscle located at the back of the head. It is one of the muscles that make up the scalp. The occipitalis muscle is responsible for moving the scalp and for raising the eyebrows. It is innervated by the occipital artery and the greater occipital nerve.
The occipitalis muscle is thin and flat, and it is attached to the bone at the back of the head called the occipital bone. It is divided into two parts: the front part and the rear part. The front part is responsible for raising the eyebrows, while the rear part is responsible for moving the scalp.
The occipitalis muscle is used in a number of different facial expressions, including surprise, worry, and anger. It is also used when shampooing the hair or scratching the scalp.
In some cases, the occipitalis muscle can become strained or overworked, leading to pain and discomfort. This can be caused by excessive use of the muscle, such as when raising the eyebrows frequently or vigorously scratching the scalp. Treatment may involve resting the muscle, applying heat or cold to the area, or using over-the-counter pain medications.
