sensory root

root

[roōt] 1. the descending and subterranean part of a plant.2. that portion of an organ, such as a tooth, hair, or nail, that is buried in the tissues, or by which it arises from another structure, or the part of a nerve that is adjacent to the center to which it is connected.

Tooth anomalies with variations in root form. From Darby and Walsh, 1994.anterior root the anterior, or motor, division of each spinal nerve, attached centrally to the spinal cord and joining peripherally with the posterior root to form the nerve before it emerges from the intervertebral foramen; it conveys motor fibers to skeletal muscle and contains preganglionic autonomic fibers at the thoracolumbar and sacral levels. Called also ventral root.dorsal root posterior root.motor root anterior root.nerve r's the series of paired bundles of nerve fibers which emerge at each side of the spinal cord, termed dorsal (or posterior) or ventral (or anterior) according to their position. There are 31 pairs (8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal), each corresponding dorsal and ventral root joining to form a spinal nerve. Certain cranial nerves, e.g., the trigeminal, also have nerve roots.posterior root the posterior, or sensory, division of each spinal nerve, attached centrally to the spinal cord and joining peripherally with the anterior root to form the nerve before it emerges from the intervertebral foramen; each posterior root bears a spinal ganglion that conveys sensory fibers to the spinal cord. Called also dorsal root.sensory root posterior root.ventral root anterior root.

root

(root) 1. The underground part of a plant.2. A bundle of pia-covered axons that emerges from or enters into the brain or spinal cord inside the dura; the central-most end of a peripheral nerve, inside the dura.3. A portion of an organ implanted in tissues. Synonym: radix4. The part of the human tooth covered by cementum; designated by location (mesial, distal, buccal, lingual).5. In the coastal regions of the southeastern U.S., esp. among those of Caribbean or African descent, a hex or spell, esp. one that relies on herbal rituals to produce or heal disease.

anterior root

One of the two roots by which a spinal nerve is attached to the spinal cord; contains efferent nerve fibers.

posterior root

One of the two roots by which a spinal nerve is attached to the spinal cord; contains afferent nerve fibers.
