WebJan 28, 2024 · Dendrites are parts of neurons that are found throughout the body, that is, both in the brain and spinal cord and in those that are in the ganglia, internal organs, muscles, etc. Specifically, dendrites are small branches that come out of the cell body (the part of the neuron where the cell nucleus is located). WebFor example, the dendrites of cat spinal motoneurons have a volume of 300,000 μm 3 and provide a surface area of 370,000 μm 2 for synaptic input (Ulfhake and Kellerth, 1981). To provide an equivalent surface area, a spherical cell body would have to have a diameter of 342 μm and a volume of more than 20,900,000 μm 3 , a factor of 70 greater ...

WebMar 11, 2024 · According to one idea, called the synaptotrophic hypothesis, synapses stabilize dendrites and make them more likely to grow further, while dendrites without synapses are more likely to recede.... WebMay 20, 2024 · The element analysis showed that the dendrites do not grow directly from the soldering pads. The surface finish therefore does not have a direct influence on dendrites, but rather on the chemical compound that is formed between the surface finish and the solder. These compounds are then prone to electrochemical migration.

WebMost proteins are synthesized in the cell body, but some are clearly synthesized in proximal parts of dendrites, where masses of rough ER are found, and are transported distally … For metals the process of forming dendrites is very similar to other crystals, but the kinetics of attachment play a much smaller role. This is because the interface is atomically rough; because of the small difference in structure between the liquid and the solid state, the transition from liquid to solid is somewhat gradual and one observes some interface thickness. Consequently…
