Epicranial aponeurosis. Muscles of the head, face, and neck. (Epicranial aponeurosis visible at top labeled 1.) The epicranial aponeurosis (aponeurosis epicranialis, galea aponeurotica) is an aponeurosis (a tough layer of dense fibrous tissue). It covers the upper part of the skull in humans and many other animals.
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 ...
Aponeurosis. An aponeurosis (/ ˌæpənjʊəˈroʊsɪs /; 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 ...
The majority of neonatal cases (90%) result from applying a vacuum to the head at delivery (ventouse-assisted delivery).The vacuum assist ruptures the emissary veins (i.e., connections between dural sinus and scalp veins) leading to accumulation of blood under the aponeurosis of the scalp muscle and superficial to the periosteum.
Superficial muscular aponeurotic system. Superficial muscular aponeurotic system (or superficial musculoaponeurotic system[1]) (SMAS) is a thin yet tough [2]: 438 unitary tissue plane of the face [3] formed by facial fasciae, subcutis connective tissue, and facial muscles. [2]: 438 Its composition varies, containing muscle fibres in some areas ...
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 frontalis muscle is thin, of a quadrilateral form, and intimately adherent to the superficial fascia. It is broader than the occipitalis and its fibers are longer and paler in color. It is located on the front of the head. The muscle has no bony attachments. Its medial fibers are continuous with those of the procerus; its intermediate ...
46856. Anatomical terms of muscle. [edit on Wikidata] The anterior auricular muscle, the smallest of the three auricular muscles, is thin and fan-shaped, and its fibers are pale and indistinct. It arises from the lateral edge of the epicranial aponeurosis, and its fibers converge to be inserted into a projection on the front of the helix.
