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 neurons send impulses from the CNS to the muscle, organ or gland they command to take action. Motor neurons have short dendrites and long axons. Their dendrites and cell body are in the spinal cord and their axons are found in the muscle, organ or gland that they innervate. They can be over one metre long.3.. Sensory neurons send impulses from sensory receptors to inform the CNS of a stimulus. A sensory receptor is a structure that recognises a change in its environment. Sensory neurons have long dendrites and short axons.
