What is Meningeal Release?
The dura mater is firmly attached

Atlas, Axis and third cervical

the first coccygeal segment
What is Meningeal Release?
In coccyx imbalances, abnormal stress
can be applied to the dura mater
causing reflex muscle tension along the
Goodheart has described the coccyx as a
take up mechanism to keep constant
tension on the dura mater.
Tension on the dura appears to be
controlled by the coccyx
Increased muscle contraction along the
spine from the lumbars through the
Increased pterygoid pocket tenderness
Leg edema - tenderness
Dropped bladder - uterus

mm. (use rolling tape measure from
coccyx to occiput)

Coccygeus is often described as the
muscular belly of the sacrospinous ligament
with which it is fused to on its pelvic aspect.
The coccygeus is occasionally absent, in which
case the sacrospinous ligament is more

Its base is attached to the lateral aspect of the coccyx

Coccygeus Nerve Supply
A branch of the sacral plexus, derived from

The coccygeus muscle functions with the levator ani
forming the majority of the pelvic diaphragm, which
supports the pelvic viscera.
When the coccygeus and the levator ani contract with
the muscles of the abdominal wall, they help to raise
intra-abdominal pressure in such processes as
coughing, vomiting and forced expiration.
They can also become involved in inspiration during

posterior inferior iliac spines, the posterior surface of the
sacrum (where it blends with the posterior (dorsal) sacro-
iliac ligaments), the lateral aspect of the lower sacrum and
to the upper surface of the coccyx.
The fibers converge as they pass downwards and laterally.
They twist on themselves and then diverge to attach to the
medial margin of the ischial tuberosity and the lower
margin of the ischial ramus.
Distal fibers of gluteus maximus attach to the ligaments
