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.

Problems caused by biofilms. BÃ¸rge K. Mortensen. Bactoforce International A/S. Biofilms will form on critical locations in processing plants in the food and beverage. industries, where nutrients are available and where cleaning and disinfection are. inadequate. Formation of biofilms can lead to a number of problems such as product. spoilage, food safety problems, and loss of production efficiency. Countermeasures against biofilms are therefore in focus in good manufacturing practice. A general problem caused by biofilms is that some cellular by-products accelerate corrosion of stainless steel. Other problems are that biofilm formation in heat exchangers reduces the fluid flow and the heat transfer; and in membrane filtration units, biofilm will block membrane pores, which decreases the flux of permeate,
