Fig. 2.6 If we just look at adductor longus and the short head of
the biceps femoris (as on left), they appear to fulfill the
requirements for a myofascial continuity. But when we see that the
plane of adductor magnus intercedes between the two (as on
right) to attach to the linea aspera, we realize that such a
connection breaks the rules.

connection through the hip bone.
tibialis anterior muscle (see Ch. 6 for both of these exam-
ples). The rectus abdominis and the rectus femoris,
however, have scant direct fascial connection without
turning sharp corners, but have an indirect mechanical
connection through the pelvic bone in sagittal (flexion-
extension) motions, such as anterior and posterior tilt of
the pelvis (Fig. 2.5 and see Ch. 4).
D. Intervening planes
Resist all temptation to carry an Anatomy Train through
an intervening plane of fascia that goes in another direc-
tion, for how could the tensile pull be communicated
through such a wall? As an example, the adductor
longus comes down to the linea aspera of the femur, and
the short head of the biceps goes on from the linea
aspera in the same direction. Surely that constitutes a
myofascial continuity? In fact it does not, for there is the
intervening plane of the adductor magnus, which would
cut off any direct tensile communication between longus
and biceps (Fig. 2.6). Again, there may be some mechani-
cal connection between these two, as in the example
given in C above, but a direct fascial communication is
negated by the fascial wall between.
Fig. 2.7 In this photo of a recent dissection, a series of muscles
were detached from their attachments to show the continuity of
fascial fabric from muscle to muscle independent of the skeleton.

double-bag theory), a station is where the outer myofas-
cial bag attaches itself onto the inner 'osteoarticular'
The more superficial fibers of the myofascial unit,
however, can demonstrably be seen to run on, and thus
communicate, to the next piece of the myofascial track.
For instance, in Figure 2.1 B we can see that some of the
fibers at the end of the myofascia on the right are clearly
tied to the ribs, while some fibers continue on into the
next 'track' of myofascia. In Figure 2.7, we can clearly
see that when the rhomboids, serratus anterior and the

bony stations' or attachments
In the Anatomy Trains concept, muscle attachments
('stations') are seen as places where some underlying
fibers of the muscle's epimy sium or tendon are enmeshed
or continuous with the periosteum of the accompanying
bone, or, less often, with the collagen matrix of the bone
itself. In the terms we set out in Chapter 1 (section on
