MeSH Fascia

Fascia (făsh'ē-ə), pl. fas·ci·ae (făsh'ē-ē), adj. fascial (făsh'ē-əl) (from latin: a band) is a layer of fibrous tissue[1] that permeates the human body.

It interpenetrates and surrounds muscles, bones, organs, nerves, blood vessels and other structures. Fascia is an uninterrupted, three-dimensional web of tissue that extends from head to toe, from front to back, from interior to exterior.

Layers of the fascia

There exists some controversy about what structures are considered "fascia", and how fascia should be classified.[2] The two most common systems are:

NA 1983 TA 1997 Description Example
Superficial fascia (not considered fascia in this system) This is found in the subcutis in most regions of the body, blending with the reticular layer of the dermis. [3] Fascia of Scarpa
Deep fascia Fascia of muscles This is the dense fibrous connective tissue that interpenetrates and surrounds the muscles, bones, nerves and blood vessels of the body. Transversalis fascia
Visceral fascia Visceral fascia, parietal fascia This suspends the organs within their cavities and wraps them in layers of connective tissue membranes. Pericardium

From LoveToKnow 1911

FASCIA (Latin for a bandage or fillet), a term used for many objects which resemble a band in shape; thus in anatomy it is applied to the layers of fibrous connective tissue which sheathe the muscles or cover various parts or organs in the body, and in zoology, and particularly in ornithology, to bands or stripes of colour. In architecture the word is used of the bands into which the architrave of the Ionic and Corinthian orders is subdivided; their origin would seem to have been derived from the superimposing of two or more beams of timber to span the opening between columns and to support a superincumbent weight; the upper beam projected slightly in front of the lower, and similar projections were continued in the stone or marble beam though in one block. In the Roman Corinthian order the fasciae, still projecting one in front of the other, were subdivided by small mouldings sometimes carved. The several bands are known as the first or upper fascia, the second or middle fascia and the third or lower fascia. The term is sometimes applied to flat projecting bands in Renaissance architecture when employed as string courses. It is also used, though more commonly in the form "facia," of the band or plate over a shop-front, on which the name and occupation of the tradesman is written.
