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
Loose connective tissue skin and mucous membranes, it is more compact and sometimes difficult to distinguish from dense irregular connective tissue. Areolar connective tissues hold organs in place and attaches epithelial tissue to other underlying tissues. It also serves as a reservoir of water and salts for surrounding tissues. Almost all cells obtain their nutrients from and release their wastes into areolar connective tissue. Organs that are rich in loose connective tissue(such as the eyelids) are usually sites that undergo oedema indicating renal failure or nephrotic syndrome. Thus periorbital swelling is one characteristic finding in severe renal disease Loose connective tissue Loose connective
