Visionary Craniosacral Work® 2 – Advanced Content Class
Visionary Craniosacral Work® with the Second Cervical Vertebra
In this one-day, eight-hour class students will focus on the anatomy, physiology and manual therapy techniques as applied to C2, the axis. This study will encompass bone and soft-tissue landmarks, building outwards from the axis, to include the upper cervical spinal domain, the mediastinum, the cranial base bone structures, and the Myodural Bridge. Students will learn the basic formations involved in the embryology of the vertebral column, noting the differentiation of ectoderm, mesoderm and endoderm in the emergence of the primitive streak. Building on the understanding of embryological development and ossification chronology, we will study the relationship of the axis to the spinal dura and the brainstem. There are six ways in which C2 is important in craniosacral work and in the human body:
1 – It is the anchor vertebra that acts as the osseous fulcrum of the ‘Myodural Bridge’ that includes the suboccipital musculature, the connective tissue attachments from ligamentum nuchae to the spinal dura mater, and the spinal dura connection to the axis. The attachments between ligamentum nuchae and the rectus capitus posterior major and the spinal dura occur between vertebrae C1 – C2, and between the occiput and the atlas, C1. The bony interrelationships include the connection of the axis to the mediastinum, and the insertion of the mediastinum into the temporal, occipital and sphenoid bones.
2 – Rectus capitus posterior major, inferior oblique and the ligamentum nuchae all attach to the axis and play a crucial role in tension type, migraine and cluster headache, in addition playing a lesser role in vertigo, whiplash injury and generalized neck pain.
3 — Longus capitus, longus collis and all three (sometimes four) scalene muscles have origins at C2. Students will deepen their understanding of how the anterior and lateral cervical musculature, including longus capitus, longus collis and the scalene group help stabilize cervical spine function, particularly after whiplash injury. Facilitating the return of optimum muscular balance at C2 helps these muscles find balance, which can be beneficial in shoulder-arm-hand syndrome, rotator cuff injury, frozen shoulder, and asthma.
4 – The dens part of the axis represents the center of dynamic contractile power for 136 muscles of mastication and head-neck-back mobility of Guzay’s Theorum, itself central to temporomandibular joint dysfunction (TMD).
5 – The spinal cord level of the axis is also the level where the sensory branch of CN V, the trigeminus, begins. For this reason, changes in the muscoloskeletal balance at the level of the axis can play a role in CN V dysfunction, including temporomandibular joint dysfunction (TMD). The proximity of the motor nucleaus of trigeminus and to the Reticular Activating System and its sensitivity to caffeine stimulation is a frequent exacerbating factor in headache and in TMD.
6 – It is close to the acupuncture point Small Intestine 17, ‘Heavenly Appearance,’ with its therapeutic relationship to tinnitus, deafness, and a lack of groundedness in the world.
Students will be shown manual therapy and Visionary Craniosacral Work® approaches to working with the axis. In the final segment of the class students will give and receive a 90-minute craniosacral protocol using manual therapy contacts to facilitate optimum function at the level of C2, the Axis.
