Innervation of the human cervical and thoracic vertebrae at eight postovulatory weeks
Folia Morphol 2009;68(2):84-87.
Abstract
The nerves to the cervical and thoracic vertebrae were traced in 10 serially
sectioned human embryos. It was found that the vertebral bodies receive nerve
fibres from the trunks of the spinal nerves, anterior branches and meningeal
branches of the spinal nerves, and from the sympathetic trunks. Slender twigs
from the trunk of the spinal nerve arise close to the spinal ganglion and terminate
in the posterior and lateral surfaces of the vertebrae. Fibres from the anterior
branches of the spinal nerves terminate in the lateral and anterior surfaces
of the vertebrae. Thin rami from the sympathetic trunk reach the anterior surface
of the vertebrae.
