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.
There are different forms of motor neuron disease. 1  ALS (amyotrophic lateral sclerosis) is the most common form and accounts for approximately 60% to 70% of all cases. 2  PBP (progressive bulbar palsy) accounts for about 20% of all cases.n 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.
