Cell Fractionation
Cell fractionation is a combination of various methods used to isolate (fractionate) cell structures based on size and density. This technique takes cells apart and separates major organelles and other subcellular components from one another. There are two phases of cell fractionation: homogenization and centrifugation. Homogenization is the process of breaking open the cells, usually

Motor Neurons (UMN & LMN)
Upper motor neurons (UMN) are a type of first order neuron. They are unable to leave the central nervous system. The pyramidal tract is a very important upper motor neuron tract. The extrapyramidal tract also consists of upper motor neurons, and is multi synaptic. As upper motor neurons must remain inside the neuraxis, they synapse with

Diffusion vs Osmosis
Diffusion is the movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. A good example of diffusion is food colouring. If you place a drop of red food colouring in a beaker of water eventually the entire beaker of water will have
