Galea aponeurotica
The galea aponeurotica (syn. Aponeurosis epicranialis ) is a tough tendon cover or plate on the roof of the skull . It extends between the frontal and occipital parts of the occipitofrontalis muscle . The frontal part, also called the frontalis muscle, is used to lift the eyebrows and the forehead. The skin muscles that attach to the galea aponeurotica are called the epicranium muscles .
The galea aponeurotica is firmly attached to the scalp . This is done by connective tissue fibers ( retinacula cutis ) that extend perpendicular to the dermis . As a result, the galea aponeurotica, skin and subcutaneous tissue form a unit known as the scalp . The special anatomy of the galea aponeurotica allows the scalp a certain degree of flexibility with regard to movements to the forehead (frontal), to the back of the head (occipital) and to the side (lateral, temporal, parietal), which is known medically as mobility.
