Anatomy

The frontalis muscle is a paired muscle, which means that there is one on each side of the forehead. The two muscles are joined together through a fibrous band called the epicranial aponeurosis.

It is also attached to the occipital bone at the back of the head by the occipitalis muscle. It is primarily composed of skeletal muscle fibers.

Location

The frontalis muscle is located on the forehead, just above the eyes. It extends from the hairline down to the eyebrows.

Functions

1- Facial Expression: The most common function of this muscle is raising the eyebrows. When you’re surprised, intrigued, or trying to express curiosity, the Frontalis muscle goes to work, lifting your brows and creating a distinctive look.

2- Forehead Movement: It also enables the skin of the forehead to move, allowing for wrinkling and smoothing. This function is crucial for conveying emotions like concern, confusion, or concentration.

Nerve Supply

This muscle is innervated by the facial nerve. The facial nerve is one of the twelve cranial nerves, and it controls all of the muscles in the face.

Blood Supply

The frontalis muscle is supplied blood by the supraorbital artery and the supratrochlear artery. These arteries are branches of the external carotid artery.

Common Frontalis Muscle Issues:

1- Frontalis Muscle Tension: Excessive tension in the Frontalis muscle can lead to discomfort and headaches. Common causes include stress, prolonged periods of frowning, or facial muscle strain.

Symptoms: Headaches, facial pain, tension lines on the forehead.

Treatment: Stress management, facial relaxation techniques, massage, and stretching exercises.

2- Frontalis Muscle Weakness: Weakness in this muscle can result from disuse or muscle atrophy. It can affect your ability to raise your eyebrows and convey emotions effectively.

Symptoms: Difficulty in raising eyebrows and diminished facial expressiveness.

Treatment: Facial exercises, physical therapy, and targeted muscle strengthening.
