| spermatic cord torsion | Torsion of the spermatic cord caused usually by incomplete attachment of the epididymis to the testis or by inclusion of the cord within the tunica vaginalis. Faulty development of various anatomical components of the testes is also a cause. It occurs most frequently in childhood and adolescence. (12 Dec 1998) |

| spinal cord | <anatomy> Elongated, approximately cylindrical part of the central nervous system of vertebrates that lies in the vertebral canal and from which the spinal nerves emerge. (18 Nov 1997) |
| spinal cord compression | A condition in which pressure is exerted on the spinal cord, as by a tumour, spinal fracture, etc. Its manifestations, which vary with location and degree of pressure, may include pain, paresthesias, and sensory and motor disturbances. (12 Dec 1998) |
| spinal cord concussion | Injury to the spinal cord due to a blow to the vertebral column with transient or prolonged dysfunction below the level of the lesion. Synonym: spinal concussion. (05 Mar 2000) |
| spinal cord injuries | Injuries to the spinal cord, that is, the part of the central nervous system that is situated within the vertebral column. (12 Dec 1998) |
| spinal cord injury | Any injury to the spinal cord via blunt or penetrating trauma. Extreme flexion or extension (particularly in the neck) of the spine can result in traction on the spinal cord with subsequent injury and the development of neurologic symptoms. See: neurologic symptoms. (27 Sep 1997) |
| spinal cord neoplasms | Neoplasms located in the spinal cord. They include neoplasms in the inner core or the outer layer of the cord, but not those in the protective membranes, or meninges ( = meningeal neoplasms). (12 Dec 1998) |
| spinal cord tumour | A spinal cord tumour is a aggregate if cells that form a mass that can compress the spinal cord. Spinal cord tumours may arise from local structures (for example meninges) or from a cancer from a distant site (i.e. Metastasis). Regardless of the aetiology, all spinal cord tumours cause symptoms from compression on the spinal cord, surrounding nerve roots or blood vessels that supply the cord. Symptoms are variable with the extent and the level of the spinal cord tumour. Common symptoms include back pain that may radiate, numbness and tingling to the lower extremities, muscle weakness in the legs, difficulty walking and loss of bowel and bladder control (incontinence). (27 Sep 1997) |
| nephrogenic cord | A longitudinal dorsolateral tract of mesoderm derived from intermediate mesoderm; the primordium for both mesonephric and metanephric tubules. (05 Mar 2000) |
| subacute combined degeneration of the spinal cord | A subacute or chronic disorder of the spinal cord, such as that occurring in certain patients with vitamin B12 deficiency, characterised by a slight to moderate degree of gliosis in association with spongiform degeneration of the posterior and lateral columns. Synonym: combined sclerosis, combined system disease, funicular myelitis, Putnam-Dana syndrome, vitamin B12 neuropathy. (05 Mar 2000) |
| dental cord | <dentistry> An aggregation of epithelial cells forming the rudimentary enamel organ. (05 Mar 2000) |
| dentate ligament of spinal cord | Rarely used variation on the spelling of denticulate ligament. (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) |
| 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) |
