The foundation of craniosacral therapy consists of rhythmic cranial impulses. Those impulses (=The Primary Respiration) are generated by the cerebrospinal fluid (CSF) and include the central nervous system (CNS), the reciprocal tension membrane system, the cranial bones, the sacrum and part of the hip.

The cerebrospinal fluid (CSF):

  • Is produced in the brain through a ventricular system

  • Protects the brain

  • Is an important store / carrier of potency (=energy and information)

  • Provides essential nourishment to the central nervous system (CNS)

  • Increases the distribution and action potential of the central nervous system

  • Inherent fluctuation of CSF= Pressure builds up and releases

The central nervous system (CNS) exists of:

  • Brain is situated in the skull

  • Spinal cord is housed inside the vertebral column and the sacrum.

  • Cranial / Spinal / Peripheral nerves

  • Sensory (receptor) neurons and motor (action) neurons

  • Relay neurons allow neurons to communicate

  • The CNS transmits information

  • Inherent motility of CNS = the motion of brain and spinal cord

The central nervous system (CNS) is contained within a system of connective tissues called reciprocal tension (=dural) membranes (RTM):

  • Main RTM are: the falx cerebri, the tentorium cerebelli and the dura mater.

  • The RTM gives protection to the central nervous system.

  • The mobility of RTM = the natural motion of different parts of RTM

The cranial sutures are present to express small degrees of motion of the cranial bones.

  • The motion of the RTM creates the movement of the cranial bones.

The involuntary motion of the sacrum and the iliac bones (= part of the hip).

  • The motion of the spinal cord creates the movement of the sacrum and the iliac bones.
