The Sensitive Nervous System Chapter V: Neurodynamics

This is a summary of Chapter V of “The Sensitive Nervous System” by David Butler. Intro Neurodynamics is the study and relationship of nervous system mechanics and physiology. The testing protocols for neurodynamics assess the nervous system’s ability to lengthen, glide, and change amongst interfacing structures. When discussing neurodynamics, it is important to think of the nervous system as a continuum. Mechanical, electrical, and chemical changes in one part of the nervous system affect other related parts. Gross Movements and Dynamics When having a nervous system, the following qualities, movements, and buffering capabilities are necessary: Slide, glide, strain. Elongate (think gymnasts) and return from elongated position. Compress (ulnar nerve during elbow flexion). Stength (kicking a field goal). Jolting (whiplash). Repetitive forces Bending Fluid/chemical selectivity. Neural Connective Tissue These include the meninges, nerve root complex, and peripheral nerve structures. Broken down as follows: Meninges Dura mater (outer, tougher) Arachnoid mater Pia mater (inner, thinner) Nerve root complex Root Sleeve Dorsal and ventral roots DRG Spinal nerve. Peripheral nerves Epineurium Perineurium Endoneurium Mesoneurium – Sheath that surrounds a nerve. Contracts like an accordion to glide along adjacent tissues. Can become fibrotic with injury. Important Attachments Meningovertebral ligaments – anchor down to spinal canal, which could become symptomatic. Rectus capitus posterior is connected to the dura mater between the occiput and atlas; helping the dura fold. Makes you wonder what you are truly doing when you release this structure. The sympathetic trunk’s proximity to the spinal column makes it susceptible to increased loads
