ism to the middle, and to take otherwise toxic chemistry
from the middle to the edge where it can be dispersed.
The organs of the ventral cavity - the lungs, the heart,
the digestive system, and the kidneys - are designed to
provide this service for the inner cells of the body To
provide a comprehensive 'inner sea' complete with
nourishing and cleansing currents, the network of capil-
laries must penetrate into the immediate neighborhood
of most individual cells of whatever type to be able to
deliver the goods via diffusion from the capillary walls.
Cartilage and ligament injuries take longer to heal
because their cells are so far from the shores of this inner
sea that they must rely on seepage from farther away.
The fibrous net
It can be no surprise, given our subject, that the fascial
system is our third whole-body communicating network;
the only surprise is how little the importance of this
network has been recognized and studied as a whole
until recently (Fig. 1.23).
Fig. 1.22 Even the brain itself is full of blood vessels (and the
heart is full of nerves). Is it only the neurons of the brain that
'think'? (© Ralph T Hutchings. Reproduced from Abrahams et al
Fig. 1.23 (A) Vesalius shows the fibrous net in the familiar way - as a layer of muscles - but the overlying layers of fascial fabric have
been removed. (B) The second view shows a deeper layer of musculature; fascial septa would fill in all the gaps and lines among the
muscles. In (B), notice the black line extending from the bottom of the diaphragm to the inside arch of the foot, and compare it to the
Deep Front Line (see Ch. 9). (Reproduced with permission from Saunders JB, O'Malley C. Dover Publications; 1973.)
