Ventral Root of Spinal Nerves

A ventral root as well as a dorsal root combines to create a spinal nerve, which travels outside from the vertebral canal via an intravertebral foramen (bone opening). The ventral root (motor root) of every single spinal nerve includes axons from motor neurons whose cell bodies are

Dorsal Rami

31 pairs of spinal nerves are found in the human body. All spinal nerves originate from a ventral root as well as a dorsal root. The combination of many dorsal as well as ventral root filaments or rootlets forms each root. All spinal nerve almost directly split
