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.

Top 10 unbelievable historical concurrencies. Transcriptional regulation is a term used to describe a number of biological processes by which transcription, the process through which the genetic data stored in DNA is transcribed to RNA, is controlled.egulation of gene expression can occur at every level of the central dogma of biology. Transcriptional regulation is a specific form of gene regulation that occurs during the transcription process by moderating the rate of transcription.
