The authors trace the etymology and historical significance of galea or epicranial aponeurosis. In ancient Greece, galea referred to a helmet worn by soldiers, typically made of animal hide or leather.
Is the galea aponeurotica a tendon?
Over the dome of the skull the epicranium is formed by a sheet of tendon that’s known as the galea, or galea aponeurotica. Two muscles are attached to the galea, in front, the frontalis, and behind, the occipitalis. The occipitalis muscle arises from here on the occipital bone, above the superior nuchal line.
What is the galea capitis?
part of the head, the so-called head cap, galea capitis. It is a very thin, closely-fitting membrane, completely covering the acrosome. Its rear. edge forms a transversal ridge around the head, just behind the equator.
What is the purpose of epicranial aponeurosis?
The epicranial aponeurosis provides the insertion point for the occipitofrontalis muscle, a thin, broad muscle that covers the top of your skull. This muscle controls many of your facial expressions. Every time you raise your eyebrows, you can thank your occipitofrontalis muscle and your epicranial aponeurosis!
What type of tissue is the galea?
The galea aponeurotica (also called the galeal or epicranial aponeurosis or the aponeurosis epicranialis) is a tough fibrous sheet of connective tissue that extends over the cranium, forming the middle (third) layer of the scalp.
Is there galea on the forehead?
The scalp is traditionally considered in 5 layers: skin, subcutaneous tissue, galea aponeurotica, loose areolar tissue, and periosteum. These layers continue into the forehead, where, in the region of the eyebrow, galea gives way to the muscles of facial expression.

What is galea aponeurotica in skeletal muscle?
Epicranial Aponeurosis also referred to as the Galea Aponeurotica or the aponeurosis epicranialis is a broad tendon and is the intermediate section of the occipitofrontalis muscle. It is in between the frontalis muscle that lies on the frontal bone and the occipitalis muscle that lies on the occipital bone.
What does the aponeurosis do?
1. A: aponeuroses are extensions of external tendons on the surface of pennate muscles that function as insertion sites for muscle fascicles and may play a role in modulating fascicle rotation and dynamic gearing during muscle contractions.
How do you suture galea?
Only the galea is sutured. By tacking a sufficient width of the galea on both sides with an absorbable suture material, the sutured wound forms a ridge. The outer layer is then closed with skin staples to keep the blood circulation undisturbed.
What two muscles attach into the galea aponeurotica What is the name of this collective structure?
Galea Aponeurotica It originates on the occipital bone and inserts into both the occipitalis and frontalis muscles.
