Follicular dendritic cells Follicular dendritic cells. Follicular dendritic cells (FDCs) are cells of the immune system found in primary and secondary lymph follicles of the B cell areas of the lymphoid tissue. These cells were first described in 1965 and, although they have a very dendritic morphology, are not dendritic cells (DCs).

What is a Debris Flow? A debris flow is a moving mass of loose mud, sand, soil, rock, water and air that travels down a slope under the influence of gravity. To be considered a debris flow the moving material must be loose and capable of flow, and, at least 50% of the material must be sand-size particles or larger. mud flow is composed of mud and water. Debris flows have larger particles-at least 50% of a debris flow is made-up of sand-size or larger particles. Debris flows can be triggered by many different situations.

Adaptive Immune Response Dendritic cells are immune cells that process antigen material; they are present in the skin (Langerhans cells) and the lining of the nose, lungs, stomach, and intestines. Sometimes a dendritic cell presents on the surface of other cells to induce an immune response, thus functioning as an antigen-presenting cell.

Dendrite Dendrites, also dendrons, are branched protoplasmic extensions of a nerve cell that propagate the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project. Electrical stimulation is transmitted onto dendrites by upstream neurons via synapses which are located at various points throughout the dendritic tree. Dendrites play a critical role in integrating these synaptic inputs and in determining the extent to which action potentials are produced by the neuron. Dendritic arborization, also known as dendritic branching, is a multi-step biological process by which neurons form new dendritic trees and branches to create new synapses. The morphology of dendrites such as branch density and grouping patterns are highly correlated to the function of the neuron.

debris Debris is trash scattered around after a disaster, like shattered glass on the road after a car accident. Debris comes from French for waste, rubbish. Although debris usually refers to the trash leftover after some kind of explosion or crash, it can also be what's on your floor after hosting a kid's make-your-own pizza party, or what you shouldn't leave at the park after a picnic.

- Dendritic cells are found, for example, in the lymph nodes and spleen. As an APC, a dendritic cell can retain antigen for long periods on its surface, present the antigen to a T or B cell and so influence their behavior. The word dendritic means branched like a tree.. It comes from the Greek dendron (tree).

- what is granular disintegration in dry climates a What is granular disintegration In dry climates a yet another mechanism operates much like frost action, in this process the ground water is drawn to the surface, which on evaporation leaves behind salts such as halite, calcite, and gypsum. This salt-crystal growth in pore spaces cracks the mineral particles apart. In igneous rocks, such as granite, water can enter into in the fractures between the grains and break up the igneous rock into its separate grains. This is called granular disintegration

Dendron and dendrite? Dendrons are nerve fibres that transmit nerve impulses towards the cell body. A motor neurone has many dendrons. The end branches of dendrons are called dendrites. The dendrites of a dendron recieve nerve impulses receive nerve impulses from other neurones.est Answer: A Dendrite is: A branched protoplasmic extension of a nerve cell that conducts impulses from adjacent cells inward toward the cell body. A single nerve may possess many dendrites. Also called dendron.

Dendritic cell 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.t certain development stages they grow branched projections, the dendrites that give the cell its name (δένδρον or dendron déndron Being greek for). Tree while similar in, appearance these are structures distinct from the dendrites of. neurons

The Immune System - in More Detail The dendritic cells are eater cells and devour intruders, like the granulocytes and the macrophages. And like the macrophages, the dendritic cells help with the activation of the rest of the immune system. They are also capable of filtering body fluids to clear them of foreign organisms and particles.

What is a Debris Flow? Addition of Moisture: A sudden flow of water from heavy rain, or rapid snowmelt can be channeled over a steep valley filled with debris that is loose enough to be mobilized. The water soaks down into the debris, lubricates the material, adds weight, and triggers a flow. mud flow is composed of mud and water. Debris flows have larger particles-at least 50% of a debris flow is made-up of sand-size or larger particles. Debris flows can be triggered by many different situations.

Transcript The most common items we find when we do shoreline cleanups are plastics. But we also find rubber, cloth, glass, metal, and paper litter. Sometimes, the debris is so tiny, like a plastic microbead from your face wash, that you can barely see it in the water. Marine debris is more than just trash in the ocean. Sometimes fishers lose their gear, like fishing traps, nets, or fishing line, and it continues to drift through the water, catching animals for a long time. We call that derelict fishing gear, and it's marine debris.

- By Dr Ananya Mandal, MD. Dendritic cells are a type of antigen-presenting cell (APC) that form an important role in the adaptive immune system. The main function of dendritic cells is to present antigens and the cells are therefore sometimes referred to as “professional” APCs.In addition, only the dendritic cells have the capacity to induce a primary immune response in the inactive or resting naive Naïve t. lymphocytesendritic cells are found in tissue that has contact with the outside environment such as the over the skin (present as Langerhans cells) and in the linings of the nose, lungs, stomach and intestines. Immature forms are also found in the blood.
