A—THE “BEGINNING.” B—THE “END.” C—THE “HEAD.” D—THE “TAIL.”
E—TRANSVERSE VEIN.

A vena cumulata has a “beginning,” an “end,” a “head,” and a
“tail,” just as a vena profunda. Moreover, a vena cumulata, and likewise
a vena dilatata, are often cut through by a transverse vena profunda.

Stringers (fibrae)6, which are little veins, are classified into fibrae trans
versae, fibrae obliquae which cut the vein obliquely, fibrae sociae,
fibrae dilatatae, and fibrae incumbentes. The fibra transversa crosses
the vein; the fibra obliqua crosses the vein obliquely; the fibra socia joins
with the vein itself; the fibra dilatata, like the vena dilatata, penetrates
through it; but the fibra dilatata, as well as the fibra profunda, is usually
found associated with a vein.
