Small bean-shaped structures scattered along the vessels of the lymphatic system. The lymph nodes produce white blood cells and filter bacteria and cancer cells that may travel through the system.

nodes of Ranvier
(ran-veer)
The small gaps in the myelin sheath between successive glial cells along the axon of a neuron; also, the site of high concentration of voltage-gated ion channels.

nodes. The leafbearing joints on plant stems.
nonpersistent virus. A virus that is carried on the mouthparts of its insect vector and is lost after the vector feeds once or a few times; styletborne virus.
internodes The stem regions between nodes in plants.
interphase The period between cell divisions when growth and replacement occur in preparation for the next division; consists of gap 1 (G1), synthesis (S), and gap 2 (G2). PICTURE ...
The nodes of this network are proteins, their corresponding mRNAs, and protein/protein complexes.
Lymph nodes, like any other tissue, receive a blood supply. When dendritic cells and lymphocytes find themselves in a venule draining the capillaries of a lymph node (called a postcapillary venule), ...
Lymph nodes are small irregularly shaped masses through which lymph vessels flow. Clusters of nodes occur in the armpits, groin, and neck.

IMPORTANT NODES
When you get older, you may get sick and your doctor will check for swollen lymph nodes. Those nodes are often found in your thighs, armpits, and neck and are essential parts of your immune system.
Hemolymph nodes or glands and hemal nodes which are so abundant in some mammals are probably not present in man.

node -- The region of a stem between two internodes, where there is branching of the vascular tissue into leaves or other appendages.
A neural network consists of layers of processing units called nodes joined by directional links: one input layer, one output layer, and zero or more hidden layers in between.
The term which Janssens (1909) introduced for the nodes (Gk. chiasma; cross) where the individual chromosomes making up each pair remain in contact during the diplotene and diakinetic stages of prophase 1 and during metaphase 1 of meiosis.
Genes can be viewed as nodes in a network, with input being proteins such as transcription factors, and outputs being the level of gene expression.
The immune system Cells in our bone marrow, thymus, and the lymphatic system of ducts and nodes, spleen, and blood that function to protect us. Antigen Anything causing an immune response, usually foreign material but may be our own tissues.
It could be a surface in the vagina, or the anal canal, or in lymph nodes if it's injected into the blood stream. The first line of defense-because you don't have time for specific responses-is the innate immune system.
(botany) the usually underground organ that lacks buds or leaves or nodes; absorbs water and mineral salts; usually it anchors the plant to the ground.The part of a tooth that is embedded in the jaw and serves as support.
A variety of white blood cells present in blood, lymph nodes, spleen, thymus gland, gut wall and bone marrow.
Another important role is to bring foreign cells, viruses and other material to the lymph nodes. Lymph nodes are scattered throughout the body. They contain large numbers of lymphocytes, produced in the bone marrow, which fight infections.
internode Region on a stem between nodes.
internuncial processes Cytoplasmic channels that connect one part of a cell to another, such as those linking the distal cytoplasm to the tegumental cytons in many flatworms.

- A type of leukocyte found in the blood, lymph nodes and certain organs. Lymphocytes are continuously made in the bone marrow (see also B lymphocytes and T lymphocytes).
The term proposed by von Winiwarter (1900), originally as an adjective, to describe the nuclei at a particular stage of prophase 1 of meiosis when the two chromosomes making up each homologous pair have separated from one another except at nodes ...
Cancer of the developing blood cells in the bone marrow. Leukemia leads to rampant overproduction of white blood cells (leukocytes); symptoms usually include anaemia, fever, enlarged liver, spleen, and/or lymph nodes. [Talking Glossary]
