What is the epicranium?

The

Although these epicranium muscles are located on the opposite sides of the skull, they are able to share the function because the gale aponeurosis is connected to them. Also known as epicranial aponeurosis or galea aponeurotica, this layer of tissue, made of dense connective fibers such as collagen and elastin, comes from the ridge above the superior nuchal line called the highest nuchal line. The stretching over the upper part of the skull and extending towards the Temporalis muscle behind the ears on both sides of the head connects to the upper part of the frontalis muscle at the top of the forehead. When the epicranial muscles are withdrawing, shortening and attracting the skin above the eyebrows up and back towards aponeurosis.

under the aponeurosis of Galea in the epicranium is another thin layer of vascular connective tissue called areolar tissue and below it is pericranium, the membrane covering the cranial bone, which is partially producedo of fibrous tissue and partly from nourishing transmission cells. Above the aponeurosis is a layer of subcutaneous or stored oily tissues and directly above it is a place where the skin begins. The skin is thick with hair follicles as well as sebaceous or oil -producing glands.
