What are the five categories of structures innervated by the Recurrent Meningeal N. and posterior Rami of Spinal Nerves involved in back pain?
Fibroskeletal sturctures (Meningeal N. ) Meninges (Meningeal N.) Synovial Joints (Posterior rami) Intrinsic back muscles (posterior rami) Spinal nerves and roots (posterior rami)
What causes muscular back pain?
Spasm in msucular tissue producing ischemia
What causes joint back pain?
Osteoarthritis or disease arthritis
What causes fibroskeletal pain?
Fractures and dislocation of ligamentous structures
What are the three layers aka spinal meninges that cover the spinal cord?
Spinal dura matter= outermost tough covering
spinal arachnoid mater= thin membranous intermediate layer, lines the spinal dural sac, held firmly to the sac by pressure of the CSF which circulate in the subarachnoid space joining the arachnoid and pia matter
Pia mater= thinnest innermost covering of the spinal cord, follows entire surface of the Spinal Cord, lines the spinal roots
