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
Biomedical tissue Biomedical tissue Biomedical tissue is biological tissue used for organ transplantation and medical research, particularly cancer research. When it is used for research it is a biological specimen. Such tissues and organs may be referred to as implant tissue, allograft, xenograft, skin graft tissue, human transplant tissue, or implant bone. Tissue is stored in tissue establishments or tissue banks under cryogenic conditions. Fluids such as blood, blood products and urine are stored in fluid banks under similar conditions. The collection, storage, analysis and transplantation of human tissue involves significant ethical and safety issues, and is heavily regulated. Each country sets
