|---|---|---|---|
| 설명 | 태아의 배꼽을 태반과 연결시키는 유일한 구조로 2개의 탯줄동맥과 1개의 탯줄정맥이 지나간다. 신생아때에는 길이가 약 50cm이다. 태생기 발생 약 5주경에 요막경(allantoic diverticulum, body stalk)으로부터 형성되며 배꼽창자관(vitello- intestinal duct) 및 요막(allantoic membrane)을 포함하고 있다. 약 1%에서 제대동맥이 하나뿐인 경우가 있는데 이때에는 선천성기형의 동반률이 증가한다. |

| cornua of spinal cord | The posterior or occipital division of the lateral ventricle of the brain, extending backward into the occipital lobe; the posterior gray column of the spinal cord as appearing in cross section. Synonym: cornu posterius ventriculi lateralis, cornu posterius, cornua of spinal cord, occipital horn. (05 Mar 2000) |
|---|---|
| sacral part of spinal cord | The part of the cord from which consists of the five sacral segments of the spinal cord (S1-S5) and from which five pairs of sacral nerves originate. Synonym: pars sacralis medullae spinalis, segmenta medullae spinalis sacralia. (05 Mar 2000) |
| segments of spinal cord | Portions of the spinal cord corresponding to the line of attachment of the roots of the individual spinal nerves. These are the cervical spinal cord segments [C1-C8]; the thoracic spinal cord segments [T1-T12]; the lumbar spinal cord segments Origin: L1-L5]; the sacral spinal cord segments [S1-S5]; and the coccygeal spinal cord segments [Co1-Co3]. Synonym: segmenta medullae spinalis. (05 Mar 2000) |
| 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) |
| 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) |
| 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) |
