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).
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.

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.
A: Aponeurosis. The epicranial aponeurosis or galea aponeurotica is a tough layer of dense fibrous tissue which anchors the above layers in place. It runs from the frontalis muscle anteriorly to the occipitalis posteriorly. L: Loose areolar connective tissue. This layer has a gel-like consistency, and allows the more superficial layers of the ...

Safe treatment shows Alzheimer’s potential. One of the challenges of treating Alzheimer’s is finding therapeutics that can cross the blood-brain barrier and get into the brain. Xenon gas can ...
It arises from tendinous fibers from the lateral two-thirds of the superior nuchal line of the occipital bone and from the mastoid process of the temporal and ends in the epicranial aponeurosis. [1] The occipitalis muscle is innervated by the posterior auricular nerve (a branch of the facial nerve) and its function is to move the scalp back. [2]
