Fascial spaces of the head and neck Fascial spaces of the head and neck Fascial spaces (also termed fascial tissue spaces or tissue spaces) are potential spaces that exist between the fasciae and underlying organs and other tissues. In health, these spaces do not exist; they are only created by pathology, e.g. the spread of pus or cellulitis in an infection. The fascial spaces can also be opened during the dissection of a cadaver. The fascial spaces are different from the fasciae themselves, which are bands of connective tissue that surround structures, e.g. muscles. The opening of fascial spaces may be facilitated by pathogenic bacterial release of
Prolidase deficiency available for the cell to reuse – not least in the synthesis of new collagen. This recycling by prolidase, seen in the image above, is essential for maintaining proline-based systems in the cell, such as the collagen-rich extracellular matrix (ECM), which serves to physically support the structure of internal organs and connective tissues. Inadequate recycling due to a dysfunctional prolidase enzyme, caused by an appropriate mutation in the pertinent gene, leads to the deterioration of that support structure and therefore the connective tissue of the skin, capillaries, and the lymphatic tissue, as is the case in PD. In particular, it
