Aponévrose

A aponévrose is a fibrous Membrane wrapping the Muscle S and constituting a separation between them. It is not an envelope but a bond between the structures on which it is dependant. It thus allows the constitution of a body.

The aponévroses are also used to delimit compartments (or cabins ) in the organization (one speaks then in general about Septum).

  • Aponévroses of intersection

Sometimes, several aponévroses can meet to give a thick membrane and much more solid called aponévrose of intersection .
Thus, the line of centers of the abdominal wall, which gathers the aponévroses musculus rectus abdominis muscles of the abdomen, is a aponévrose of intersection.
Another example: the aponévroses surface and average of the Cou (or blades surface and prétrachéale) meet in the medium to give the white line .

  • Aponévroses of insertion

the aponévroses of insertion are aponévroses which surround the muscles, thus enabling them to fit on the bones. The aponévroses recovering the muscles of the abdominal wall belong muscular to this variety of aponévroses.

Synonyms:

One speaks in general about fascia when several aponévroses rejoignent.
Exemple: the cervical fascia is the whole of the aponévroses cervical surface, average, prévertébrale and posterior.
  • Septum
One speaks about septum when the aponévrose or the fascia delimits loges.
Exemple: in the arm, the septa intermusculaires side and médial delimit the muscular cabins former and posterior.

Notez that the terms Aponévrose and Fascia are in general used indifferently one of the other, although there are certain preferences for certain structures.

The aponévrose, of coloring blanchâtre and resistant, consists of conjunctive Tissu. The conjunctive fabric is a fabric of relatively solid and fibrous support, whose role consists in protecting the bodies that it surrounds.

The aponévrose or the fascia can ignite, involving a Aponévrosite or Fasciite.

The compartments (cabins) delimited by the aponévrose and the bones can increase pressure and involve a compression of the venous and lymphatic return and a muscular Ischémie: it is the Syndrome of the cabins or Syndrome of Volkman.
