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.

Current understanding of the mechanisms of bacterial adhesion and development. Biofilm growth is governed by a number of physical, chemical and biological processes. Attachment of a cell to a substrate is termed adhesion, and cell-to-cell attachment is termed cohesion.t is believed that the effect was due to a decrease in the bacterial surface polymer at lower temperatures as well as effects such as reduced surface area. However, Herald and Zottola [65] observed that the presence of bacterial surface appendages was dependent on temperature.
