Occipitofrontalis Muscle: What You Need to Know!

What is the occipitofrontalis muscle?

The occipitofrontalis muscle consists of two bellies, where are these two bellies located?

Answer:

The occipitofrontalis is a muscle that consists of two 'bellies': the frontalis located on the forehead, and the occipitalis on the back of the skull.

The occipitofrontalis muscle, also known as the epicranius muscle, is a unique muscle that covers a large portion of the human skull. It is composed of two bellies: the frontalis and the occipitalis.

The frontal belly of the occipitofrontalis muscle is located on the forehead, while the occipital belly is situated near the occipital bone at the back of the skull. These two sections are connected not by muscle tissue, but by a broad tendon called the epicranial aponeurosis.

The frontalis muscle helps in raising the eyebrows and creating wrinkles on the forehead, while the occipitalis muscle plays a role in moving the scalp backward.

Understanding the structure and function of the occipitofrontalis muscle is crucial in comprehending the movements and expressions of the face.
