The epicranial aponeurosis (aponeurosis epicranialis, galea aponeurotica) is an aponeurosis (a tough layer of dense fibrous tissue) which covers the upper part of the cranium in humans and various other animals. This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional. On either side the epicranial aponeurosis gives origin to the anterior and the superior auricular muscles; in this situation it loses its aponeurotic character, and is continued over the temporal fascia to the zygomatic arch as a layer of laminated areolar tissue. In anatomy, the abdominal wall represents the boundaries of the abdominal cavity. The palmar aponeurosis invests the muscles of the palm, and consists of central, lateral, and medial portions. Scalp. The scalp is the anatomical area bordered by the human face at the front, and by the neck at the sides and back. The primary regions with thick aponeuroses are in the ventral abdominal region, the dorsal lumbar region, the ventriculus in birds, and the palmar (palms) and plantar (soles) regions. epicranial neurosis The arrows in the images are pointing to the Galea Aponeurotica, which is also known as the Epicranial Aponeurosis (the thin layer of Fascia that surrounds the skull). Orbicularis Oculi. The top of the forehead is marked by the hairline, the edge of the area where hair on the scalp grows. The parietal bones are two bones in the human skull which, when joined together at a fibrous joint, form the sides and roof of the cranium. Thank you for visit anatomynote.com. In humans, it is attached in the interval between its union with the occipitofrontalis muscle, to the external occipital protuberance and highest nuchal lines of the occipital bone; in front, it forms a short and narrow prolongation between its union with the frontalis muscle or frontal part of the occipitofrontalis muscle. The types of cells found in the hypodermis are fibroblasts, adipose cells, and macrophages. Please do not forget to share this page and follow our social media to help further develop our website. Not all authorities include blood or lymph as connective tissue because they lack the fiber component. The occipitofrontalis muscle is a muscle which covers parts of the skull.

Sometimes the easiest way of closing the wound may not be the ideal or best way. Some sources consider the frontalis muscle to be a distinct muscle. However, Terminologia Anatomica currently classifies it as part of the occipitofrontalis muscle along with the occipitalis muscle. They have a shiny, whitish-silvery color, are histologically similar to tendons, and are very sparingly supplied with blood vessels and nerves. In the central nervous system, the three outer membranes that envelop the brain and spinal cord are composed of connective tissue. It can help you understand our world more detailed and specific.
