Nanoparticles are particles between 1 and 100 nanometers in size. In nanotechnology, a particle is defined as a small object that behaves as a whole unit with respect to its transport and properties. Particles are further classified according to diameter. Ultrafine particles are the same as nanoparticles and between 1 and 100 nanometers in size, fine particles are sized between 100 and 2,500 nanometers, and coarse particles cover a range between 2,500 and 10,000 nanometers.
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.
Their dendrites, which receive stimuli from the environment, and their axons, which transmit information about the stimuli, are on the same fiber. The cell body sits off to the side. Multipolar neurons have several branches of dendrites and one axon. Motor neurons, which transmit instructions to muscles, and interneurons, which act as intermediaries between other types of neurons, are both multipolar neurons. Bipolar neurons, such as those in the retina, have dendrites coming out one side and an axon out the other. The connections between cells in nervous tissue are known as synapses. These are actually small gaps between the axon of one neuron and the dendrites of another, across which electrochemical signals are sent.
