| 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) |
|---|---|
| lateral column of spinal cord | A slight protrusion of the gray matter of the spinal cord into the lateral funiculus of either side, especially marked in the thoracic region where it encloses preganglionic motor neurons of the sympathetic division of the autonomic nervous system; it corresponds to the lateral horn appearing in transverse sections of the spinal cord. See: gray columns. Synonym: columna lateralis, lateral column of spinal cord. (05 Mar 2000) |
| lateral funiculus of spinal cord | The lateral white column of the spinal cord between the lines of exit and entrance of the anterior and posterior nerve roots. Synonym: funiculus lateralis, anterolateral column of spinal cord, lateral funiculus of spinal cord. (05 Mar 2000) |
| lumbar enlargement of spinal cord | A spindle-shaped swelling of the spinal cord beginning at the level of the tenth thoracic vertebra and tapering into the medullary cone, with maximum thickness opposite the last thoracic vertebra, consequential to the innervation of the lower limb. Synonym: intumescentia lumbalis, lumbar enlargement of spinal cord. (05 Mar 2000) |
| lumbar segments of spinal cord | The five lumbar segments of the spinal cord which give rise to the five pairs of lumbar spinal nerves and constitute the lumbar part of the spinal cord. Synonym: segmenta medullae spinalis lumbaria. (05 Mar 2000) |
| spinal part of accessory nerve | <anatomy, nerve> Originates from the upper five or six cervical spinal segments, emerges from the lateral surface of the spinal cord and ascends through the foramen magnum to join the cranial root. Synonym: radices spinales nervi accessorii, ramus externus nervi accessorii, pars spinalis nervi accessorii, spinal part of accessory nerve. (05 Mar 2000) |
| spinal part of arachnoid | That portion of the arachnoid which lies within the vertebral canal and surrounds the spinal cord and the vertebral portion of the subarachnoid space. It extends from the foramen magnum above to the S-2 vertebral level. Since the spinal cord ends at the L-2 vertebral level, a wide separation occurs between the arachnoid and pia mater, the lumbar cistern, filled with cerebrospinal fluid in which the cauda equina is suspended. Synonym: arachnoidea mater spinalis, spinal part of arachnoid. (05 Mar 2000) |
| coccygeal | Relating to the coccyx. (05 Mar 2000) |
| coccygeal body | An arteriovenous (arteriolovenular) anastomosis supplied by the middle sacral artery and located on the pelvic surface of the coccyx. It was formerly called a gland (of Luschka) or a glomus and included with the paraganglia. Synonym: corpus coccygeum, arteriococcygeal gland, coccygeal gland, glomus coccygeum. (05 Mar 2000) |
| coccygeal bone | <anatomy> The last bone of the spinal column, sometimes referred to as man's vestigial tail. The last portion of the vertebral column just below the sacrum. (27 Sep 1997) |
| coccygeal cornua | Two processes that project upward from the dorsum of the base of the coccyx to articulate with the sacral cornua. Synonym: cornua coccygealia, coccygeal horn. (05 Mar 2000) |
| coccygeal dimple | A depression in the skin over the coccyx caused by the caudal retinaculum. Synonym: foveola coccygea, coccygeal dimple. (05 Mar 2000) |
| coccygeal fistula | A fistulous opening of a dermoid cyst in the coccygeal region. (05 Mar 2000) |
| coccygeal foveola | A depression in the skin over the coccyx caused by the caudal retinaculum. Synonym: foveola coccygea, coccygeal dimple. (05 Mar 2000) |
| coccygeal ganglion | The most inferior, unpaired ganglion of the sympathetic trunk; inconstant. Synonym: coccygeal ganglion, Walther's ganglion. (05 Mar 2000) |
