| differential spinal anaesthesia | A form of diagnostic spinal anaesthesia producing blockade of different types of nerves in the subarachnoid space, based upon their differences in sensitivity to local anaesthetics; also observed during surgical spinal anaesthesia. (05 Mar 2000) |
|---|---|
| dorsal column of spinal cord | The pronounced, dorsolaterally oriented ridge of gray matter in each lateral half of the spinal cord, corresponding to the posterior or dorsal horn appearing in transverse sections of the cord. Synonym: columna posterior, dorsal column of spinal cord, posterior column of spinal cord. (05 Mar 2000) |
| dorsal primary ramus of spinal nerve | <anatomy, nerve> The smaller, posteriorly-directed major terminal branch (with the ventral primary ramus) of all 31 pairs of mixed spinal nerves, formed at the intervertebral foramen and turning abruptly posteriorly to divide into lateral and medial branches, both of which will supply the deep (true) muscles of the back. The medial branch (rami medialis ) of the dorsal primary ramus also supplies articular branches to the zygopophyseal joints and the periosteum of the vertebral arch. In the neck and upper back, the medial branch continues through the deep and superficial back muscles to supply overlying skin; in the lower back, the lateral branch does this. Nomina Anatomica lists dorsal primary rami as "rami dorsales" for each group of spinal nerves: 1) cervical (nervorum cervicalium ), 2) thoracic (nervorum thoracicorum ), 3) lumbar (nervorum lumbalium ), 4) sacral (nervorum sacralium ), and 5) coccygeal (nervi coccygei ). Synonym: ramus dorsalis nervorum spinalium, ramus dorsalis, rami posteriores nervorum spinalium, dorsal branch, posterior primary division. (05 Mar 2000) |
| dura mater of spinal cord | Single-layered strong membrane, comparable to and continuous with (at foramen magnum) the meningeal layer of the intracranial dura mater of the brain. It does not (in contrast to the dura mater of brain) adhere to the enveloping bony structures (vertebrae) or their periosteum, being separated from the latter by a considerable space, the vertebral epidural space-a true space containing the internal vertebral venous plexus embedded in a matrix of epidural fat. Synonym: dura mater spinalis, endorrhachis, theca vertebralis. (05 Mar 2000) |
| intermediolateral cell column of spinal cord | The cell column that forms the lateral horn of the spinal cord's gray matter. Extending from the first thoracic through the second lumbar segment, the column contains the autonomic motor neurons that give rise to the preganglionic fibres of the sympathetic system. Synonym: intermediolateral cell column of spinal cord, nucleus intermediolateralis. (05 Mar 2000) |
| isobaric spinal anaesthesia | Spinal anaesthesia of same density as cerobrospinal fluid so that the level of anaesthesia is not influenced by a change in the position of the patient. (05 Mar 2000) |
| thoracic part of spinal cord | The part of the spinal cord which consists of the twelve thoracic segments of the spinal cord from which the twelve pairs of thoracic nerves originate. Synonym: pars thoracica medullae spinalis, segmenta medullae spinalis thoracica. (05 Mar 2000) |
| thoracic spinal nerves | Twelve nerves on each side, mixed motor and sensory, supplying the muscles and skin of the thoracic and abdominal walls. Synonym: nervi thoracici. (05 Mar 2000) |
| total spinal anaesthesia | Spinal anaesthesia extensive enough to produce loss of sensation in all extracranial sensory roots. (05 Mar 2000) |
| trigeminal nucleus, spinal | Nucleus of the spinal tract of the trigeminal nerve. It is divided cytoarchitectonically into three parts: oralis, caudalis (trigeminal caudal nucleus), and interpolaris. (12 Dec 1998) |
| equine spinal ataxia | A disease of young horses characterised by progressive weakness and incoordination, most evident in the hind legs; it is associated with lesions in the cervical region of the spinal cord and is the result of compression of the spinal cord by malformed cervical vertebrae. (05 Mar 2000) |
| Erb spinal paralysis | Chronic myelitis of syphilitic origin. (05 Mar 2000) |
| erector-spinal reflex | A contraction of part of the erector spinae muscle following scratching of the skin on its outer border. (05 Mar 2000) |
| tuberculosis, spinal | Osteitis or caries of the vertebrae, usually occurring as a complication of tuberculosis of the lungs. (12 Dec 1998) |
| filum of spinal dura mater | The thread-like termination of the spinal dura mater, surrounding and fused to the filum terminale of the cord, and attached to the deep dorsal sacrococcygeal ligament; extends from S2-3 to Co2 vertebral levels. Synonym: filum durae matris spinalis. (05 Mar 2000) |
