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.

Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...
