The Galea Aponeurotica is a fibrous tissue structure located on the top of the skull. It acts as a connective layer between the skin of the scalp and the underlying muscles. This structure is part of the epicranial aponeurosis, which helps in the movement of the scalp and provides support to the overlying skin. The galea is important for the attachment of various muscles, including the frontalis and occipitalis, which are involved in facial expressions. It also plays a role in the distribution of blood vessels and nerves in the scalp, contributing to the overall health and function of the area.
