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.
Motor neuron disease (MND) is a serious and incurable form of progressive neurodegeneration-over time the nerves in the spine and brain progressively lose function. In the case of motor neuron disease, motor neurons-types of nerve cells-are affected.The renowned English physicist, Stephen Hawking, and guitar virtuoso Jason Becker are living with motor neuron disease. In all three MND forms symptoms are very similar.However, they progress at different speeds.otor neurons are found in the brain and spine. When motor neurons relay signals from the brain to the muscles and bones, the muscles move. Motor neurons are also involved in many of our automatic movements, such as swallowing and breathing.
