Ventral Root of Spinal Nerve. The ventral root (motor root) of each spinal nerve consists of axons from motor neurons whose cell bodies are found within the gray matter of the spinal cord. A ventral root and a dorsal root unite to form a spinal nerve, which passes outward from the vertebral canal through an intravertebral foramen (bone opening). A posterior branch (posterior ramus) of each spinal nerve turns toward the posterior to innervate muscles and skin of the back.
Studies to date suggest that the planktonic-biofilm transition is a complex and highly regulated process. The results reviewed in this article indicate that the formation of biofilms serves as a new model system for the study of microbial development.tudies to date suggest that the planktonic-biofilm transition is a complex and highly regulated process.

If both regulations are applicable, the one with the stricter conditions in an area would prevail. For example, FDA regulations do not allow for a waiver of inform consent for the conditions described in 45 CFR 46.116. If the study involves an FDA-regulated product, it is potentially an FDA-regulated study. The fact that the study you describe is mining data about patient response to medication prescribed as the practice of medicine does not change the fact that the product itself is FDA-regulated.
