The spinal cord is the major conduction pathway connecting thebrainThe part of central nervous system that is contained within the skull (cranium). Arising from the neural tube, the embryonic brain is comprised of three major parts including prosencephalon (the forebrain); mesencephalon (the midbrai...

The classic view of the vertebrate dorsal root ganglion is that it arises from trunk neural crest cells that migrate to positions lateral to the spinal cord, sending axons dorsally into the spinal cord and dendrites ventrally to meet with motor axons in the ventral root to form spinal nerves....

The majority of, if not all, dopaminergic innervation of the spinal cord arises from the multipolar neurons in the A11 cell group of Dahlström and Fuxe (Dahlström and Fuxe, 1964; Commissiong et al., 1978; Commissiong and Neff, 1979; Swanson and Kuypers, 1980; Skagerberg et al....
Eachspinal nervearises from the spinal cord by two roots. Theventral rootcontains motor efferent fibers from alpha motor neurons in the ventral horn of the spinal cord. Thedorsal rootcarries primary sensory afferent fibers from cells in thedorsal root ganglion. The dorsal and ventralspinal rootscom...
The pontine reticulospinal tract, however, arises from the pontine nuclei of the reticular formation, found in the ventral pons. After passing through the medulla, the pontine reticulospinal tract descends uncrossed within the anterior white column of the spinal cord. Its fibers terminate by ...

The spinal cord is part of the central nervous system and coordinates motor, sensory, and reflex signals. Anatomically, the spinal cord is located within the spinal canal and extends from the botto...
The medial vestibulospinal tract arises from the medial vestibular nucleus. It descends on the ipsilateral side of the spinal cord. It terminates by synapsing with the motor neurons in the cervical segments of the spinal cord. The major function performed by the medial vestibulospinal tract is to...
