| 설명 | 각 림프 모세관을 통해 모아진 림프액은 들림프관(afferent lymphatic vessels)을 따라 여러 림프절로 모이게 된다. 림프절에서는 림프액이 이른바 림프구로 가득찬 1차종자결절(primary germinal nodule)과 큰포식세포로 가득 찬 동굴그물을 거치게 되어서, 나쁜 병균이나 기타 이물이 면역작용을 받게되어 인체에 무해하도록 정화되어진다. 이렇게 정화된 림프액은 다시 날림프관(efferent lymphatic vessel)을 통해 다른 림프절이나 림프관으로 이동되어 결국은 가슴관(thoracic ducts)을 통해 정맥과 만나 심장으로 보내어지게 된다. 따라서 림프의 주행을 보면 다음과 같다. 간질액→림프모세관(lymphatic capillary)→들림프관→림프절→날림프관→이중 일부(주로 우측팔에 있는 림프액)는 우측 림프관으로 나머지 대부분은 가슴관(thoracic duct)으로 모여져 심장으로 감. 이러한 림프절은 인체 내에 아주 많이 존재하며, 그중 큰 것은 각기 그 위치에 따라 이름이 붙여져 있다. 악성종양이 발생시 그 전이의 형태는 혈액을 통한 혈관계 전이와 림프를 통한 림프관계전이를 통해 이루어진다. 따라서 어떤 알 수 없는 종양에서 주위 림프절의 크기가 커져 있으면, 그 종양은 악성을 의미한다고 할 수 있다. 하지만, 림프절은 단지 알 수 없는 불특정 감염에서도 면역작용에 의해 그 크기가 커지게 되므로, 림프절의 크기증가가 꼭 악성을 의미하는 것은 아니다.   |

| ranvier's nodes | Regularly spaced gaps in the myelin sheaths of peripheral axons. Ranvier's nodes allow saltatory conduction, that is, jumping of impulses from node to node, which is faster and more energetically favourable than continuous conduction. (12 Dec 1998) |

| Ranvier, Louise Antoine | <person> Was a Physician and Histologist. Professor in the College of France, Paris. Ranvier's Nodes - short specialised interruptions in the myelin sheath occurring along myelinated nerve fibres. Responsible for saltatory conduction. Lived: 1835-1922. B. Lyons, 1835, d. 1922. (05 Dec 1998) |
| Ranvier's crosses | Black or brown figures in the shape of a cross, marking Ranvier's nodes in the longitudinal section of a nerve stained with silver nitrate. (05 Mar 2000) |
| Ranvier's disks | Tactile nerve endings, of cupped disklike form, in the skin. (05 Mar 2000) |
| Ranvier's node | A short interval in the myelin sheath of a nerve fibre, occurring between each two successive segments of the myelin sheath; at the node, the axon is invested only by short, finger-like cytoplasmic processes of the two neighboring Schwann cells or, in the central nervous system, oligodendroglia cells. See: myelin sheath. (05 Mar 2000) |
| Ranvier's plexus | A subbasal stroma plexus of the cornea. See: stroma plexus. (05 Mar 2000) |
| Ranvier's segment | The portion of a myelinated nerve fibre between two successive nodes. Synonym: interannular segment, internode, Ranvier's segment, segmentum internodale. (05 Mar 2000) |
| node of Ranvier | <anatomy, physiology> A region of exposed neuronal plasma membrane in a myelinated axon. Nodes contain very high concentrations of voltage gated ion channels and are the site of propagation of action potentials by saltatory conduction. (18 Nov 1997) |
| accessory nerve lymph nodes | The nodes of the lateral deep cervical group that are located along the accessory nerve; their efferent vessels pass to the supraclavicular lymph nodes. Synonym: companion lymph nodes of accessory nerve, nodi lymphatici comitantes nervi accessorii. (05 Mar 2000) |
| anorectal lymph nodes | Nodes located on either side of the rectum; they send efferents to the middle rectal and superior rectal nodes. Synonym: nodi lymphatici pararectales, nodi lymphatici anorectales, anorectal lymph nodes. (05 Mar 2000) |
| anterior cervical lymph nodes | The group of lymph nodes located in the anterior region of the neck, divided into superficial and deep groups. Synonym: nodi lymphatici cervicales anteriores. (05 Mar 2000) |
| anterior deep cervical lymph nodes | The lymph nodes near the larynx, trachea, and thyroid gland. Synonym: nodi lymphatici cervicales anteriores profundi. (05 Mar 2000) |
| anterior group of axillary lymph nodes | Lymph nodes located along the lateral thoracic vein; they receive the drainage of the pectoral region, including most of the drainage of the breast. Synonym: nodi lymphatici axillaris pectorales, anterior group of axillary lymph nodes. (05 Mar 2000) |
| anterior jugular lymph nodes | Nodes of the lateral deep cervical group located anterior to the internal jugular vein; two nodes are specifically named: the jugulodigastric lymph node and the jugulo-omohyoid lymph node. Synonym: nodi lymphatici jugulares anteriores. (05 Mar 2000) |
| anterior mediastinal lymph nodes | Located in the superior mediastinum in relation to the great vessels, these nodes receive lymph from the thymus, pericardium and right side of the heart; their efferent vessels join those of the tracheal nodes to form the bronchomediastinal trunks. Synonym: nodi lymphatici mediastinales anteriores. (05 Mar 2000) |
