Fig. 9.38 From the central tendon of the diaphragm, the fascial
continuity travels up the pericardium and parietal pleura of the
lungs, forming sheaths and supporting webbing around all the
nerves and tubes of the pulmonary and systemic circulation. (©

Arm Line, following the path of the neurovascular bundle.

supported by the median raphe which hangs from the clivus of the
Fig. 9.39 Seen from the front, the mediastinum between the heart
and lungs connects the diaphragm to the thoracic inlet.
The major part of this middle line, however, passes
up with the esophagus into the posterior side of the
pharynx, including the pharyngeal constrictors, which
can clearly be seen hanging from the median raphe of
connective tissue in Figure 9.41 . This line also joins the
occiput (and the temporal via the styloid muscles, see
below), slightly more anterior than the upper posterior
track, attaching to a small protuberance known as the
clivus of the occiput, or pharyngeal tubercle. The poste-
rior fascia of this middle branch of the DFL (the bucco-
pharyngeal or visceral fascia) is separated from the
pos-terior line (the anterior longitudinal ligament and
prevertebral layer of cervical fascia) at this point by a
sheet called the alar fascia (Fig. 9.42).
The upper anterior track
The third and most anterior track of the DFL in the
upper body follows the curve of the diaphragm all the
way over to its anterior attachment at the xiphoid
process at the bottom of the sternum (see Fig. 9.2, side
view, upper anterior track, and DVD ref: Deep Front Line,
Part 2: 32:29-38:37). This fascia connects to the fascia on
the deep side of the sternum, although it requires a
fairly sharp turn by Anatomy Trains standards from the
nearly horizontal anteromedial portion of the diaphragm
to the endothoracic fascia on the posterior aspect of the
