The Abdominus Transversalis is a deep muscle
located in the abdomen.
As an example, to test your knowledge look at the image opposite and
decide which muscle you think the abdominus transversalis
is, then click on the image
you were correct, and for the labels of all the other muscles illustrated.
For a detailed illustration of its location see the pages about Anterior
Muscles in the Revision for Therapists
Section of the IvyRose website.
Note that it should also be easy to work out the location of
the Abdominus Transversalis because in the context of anatomy, the term
"transverse" (and it's derivatives) refers to components situated at
right-angles (i.e. perpendicular) to the long axis of either the whole
body, or a specific organ. It is generally obvious from the context whether
the component is named relative to the whole body, ot to a specific organ.
For example, the Abdominus Transversalis muscle is so named due to it's
position relative to the whole body because it is approximately perpendicular
to the main (long) axis of the human body.
