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.

Regulated Systems. A regulated system is a system of streams, creeks and rivers that is controlled or âregulated' by water storages which allow the water to be released when it is required. Almost all of the Goulburn-Murray Water systems are regulated systems.urface Water. Goulburn-Murray Water is responsible for all Victorian water ways and bodies in its region north of the Great Divide covering approximately 68,000 square kilometres. The surface water managed includes an extensive network of streams, creeks, rivers, lakes, weirs and reservoirs, and also irrigation canals.
