In humans, the epicranial aponeurosis originates from the external occipital protuberance and highest nuchal lines of the occipital bone. [1] It merges with the occipitofrontalis muscle . In front, it forms a short and narrow prolongation between its union with the frontalis muscle (the frontal part of the occipitofrontalis muscle).
It inserts into the epicranial aponeurosis. [2] the frontal belly, near the frontal bone. [1] It originates from an intermediate tendon that connects to the occipital belly. [2] It inserts in the fascia of the facial muscles and in the skin above the eyes and nose. [2] Some sources consider the occipital and frontal bellies to be two distinct ...
The epicranial aponeurosis is a tough layer of dense fibrous tissue that covers the upper part of the skull. The epicranial muscle (also called the epicranius) has two sections: the occipital belly, near the occipital bone, and the frontal belly, near the frontal bone.
Origin The bone or other structure the muscle is attached to that remains immobile during the action. The term "bone" is omitted from bone names. Insertion The attachment point of the muscle, on a bone or otherwise, that moves during the action. Artery The artery which supplies the muscle with blood.

An aponeurosis (/ ˌ æ p ə nj ʊəˈr oʊ s ɪ s /; pl.: aponeuroses) is a flattened tendon [1] by which muscle attaches to bone or fascia. [2] Aponeuroses exhibit an ordered arrangement of collagen fibres, thus attaining high tensile strength in a particular direction while being vulnerable to tensional or shear forces in other directions. [ 1 ]
The upper, often faintly marked, is named the highest nuchal line, and to it the epicranial aponeurosis is attached. The lower is termed the superior nuchal line . That area of the squamous part, which lies above the highest nuchal lines is named the occipital plane (planum occipitale) and is covered by the occipitalis muscle .
The superior auricular muscle originates from the epicranial aponeurosis. [1] Its fibres converge to be inserted by a thin, flattened tendon into the upper part of the medial surface of the auricle of the outer ear. [1] It is the largest of the three auriculares muscles. [1] It is thin and fan-shaped.
