Kinetics of the Cervical, Thoracic, and Lumbar Spine

-By "posterior half of the body," I refer specifically to the posterior skin sensation and the muscles of the back (spine). -The plexuses that supply the upper and lower limbs arise exclusively from the ventral rami. -The brachial plexus, originating from the ventral rami of C4–T1, provides sensory and motor supply to the anterior and posterior aspects of the upper limb. Likewise, the lumbosacral plexuses, also originating from their ventral rami, provide sensory and motor supply to the anterior and posterior aspects of the lower limb. -The lesser occipital nerve arises from the cervical plexus (anterior rami of C2-3), while the greater occipital nerve arises directly from (the posterior rami of C2-3). The greater occipital nerve doesn't arise from the cervical plexus. Both the greater and lesser occipital nerves are sensory nerves. -In upper crossed syndrome, which commonly results from forward head posture, the levator scapulae becomes tight after being lengthened due to the downward rotation of the scapula. This altered position subsequently places the muscle in a shortened state. -Biomechanics: Kinetic Control of the Cervical, Thoracic, and Lumbar Spine -Upper Crossed Syndrome -Sofy-Tissue Whiplash Injury -Forward Head Posture -Torticollis -Difference between Curl up and Full sit up exercises -Lower Crossed Syndrome
