Dendritic cell From Wikipedia, the free encyclopedia. Dendritic cells (DCs) are antigen-presenting cells (also known as accessory cells) of the mammalian immune system. Their main function is to process antigen material and present it on the cell surface to the T cells of the immune system.

- At other times it is found in dendritic shapes, or arborescences, resulting from minute crystals implanted upon each other. A Dictionary of Arts, Manufactures and Mines Andrew Ure. The zoœcia are not distinct from one another, but in dendritic forms the zoarium is divided irregularly by chitinous partitions.

What is a dendrite? An axon? What is the difference between the two? There is a great diagram of a nerve cell. A dendrite is the branched part of a nerve cell that recieves impulses from other nerves and sends them via AXON to other nerves which carry the impulses to the brain. The axon is the part of a nerve cell that I always thought looked like a brick. A bunch of them form the long, skinny part of the nerve cell. Axons conduct the electrical impulse through the cell and to another cell.

Transplant rejection Dendritic cells (DCs), which are the primary antigen-presenting cells (APCs), of the donor tissue migrate to the recipient's peripheral lymphoid tissue (lymphoid follicles and lymph nodes), and present the donor's self peptides to the recipient's lymphocytes (immune cells residing in lymphoid tissues).

dendrites (4) The worship of trees, plants and animals is a particular phase of the wider series of nature-cults, only named here because of its frequency and its obvious survivals in some of the higher polytheisms, where, as in Egypt, the Apis bulls were worshipped; or where, as in Mesopotamia, the great gods are partly symbolized by animal forms; or where, as in Israel, Yahweh might be represented as a bull; or where, as in Greece, such epithets as Dendrites and Endendros preserved traces of the ...

What Do Dendrites Do? Dendrites receive nervous system signals through synapses, which form the connections between neurons where the axon terminal of one nerve cell ends near the dendrites of another nerve cell. Nerve cells do not physically touch each other.

dendrite a slender branching process that extends from the cell body of a neuron and that is capable of being stimulated by a neurotransmitter. Each neuron usually possesses several dendrites, which receive synapses where chemical transmission occurs from axons to dendrites (or an axon, in the case of unipolar neurons).The number of dendrites and thus the number of synapses varies with the functions of a neuron. Also called cytodendrite.

- Dendritic cell are immune system cells whose function is to identify cancer cells, and pathogens like viruses, bad bacteria and fungus, so the the immune system T cells can then kill them. If a cancer cell is not identified by a dendritic cell, the T cells won't know it needs to be killed.

Dendrites Regardless of whether they receive sensory or synaptic input, the dendrites are the antennae of the neurons. The dendritic branching pattern varies to a great extent with the neuronal type, and is an important determinant of the synaptic or sensory input received by a neuron (Stuart et al.

Dendritic Opal Please note that Dendritic Opal is sometimes referred to by the metaphysical name of Merlinite, a crystal which is very similar in chemical composition and appearance.endritic Opal supports one’s intent and helps one to organize one’s thoughts, feelings and actions, so that one becomes discerning and is able to be accepting of others. This in turn helps one become non judgmental, just acknowledging others for who they are, an important lesson for one’s growth.

Granite The term granitic means granite-like and is applied to granite and a group of intrusive igneous rocks with similar textures and slight variations on composition and origin.ranites can be predominantly white, pink, or gray in color, depending on their mineralogy. The word granite comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a holocrystalline rock.

Dendrodendritic synapse Dendrodendritic synapses are connections between the dendrites of two different neurons. This is in contrast to the more common axodendritic synapse where the axon sends signals and the dendrite receives them. Dendrodendritic synapses are activated in a similar fashion to axodendritic synapses in respects to using a chemical synapse. These chemical synapses receive a depolarizing signal from an incoming action potential which results in an influx of calcium ions that permit release of Neurotrans
