Definition
There exists some controversy about what structures are considered "fascia", and how fascia should be classified. The two most common systems are:
- the one specified in the 1983 edition of Nomina Anatomica (NA 1983)
- the one specified in the 1997 edition of Terminologia Anatomica (TA 1997)
| 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. | 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 |

Famous quotes containing the word definition:
“Was man made stupid to see his own stupidity?
Is God by definition indifferent, beyond us all?
Is the eternal truth man’s fighting soul
Wherein the Beast ravens in its own avidity?”
—Richard Eberhart (b. 1904)
“The physicians say, they are not materialists; but they are:MSpirit is matter reduced to an extreme thinness: O so thin!—But the definition of spiritual should be, that which is its own evidence. What notions do they attach to love! what to religion! One would not willingly pronounce these words in their hearing, and give them the occasion to profane them.”
—Ralph Waldo Emerson (1803–1882)
“One definition of man is “an intelligence served by organs.””
—Ralph Waldo Emerson (1803–1882)
